(Embodiment)
Hereinafter, a development environment creation system according to an embodiment will be described with reference to the drawings.

FIG. 1 is a configuration diagram showing an example of a cloud environment 100 and a local environment 200 including a development environment construction system (construction processing server 10) according to an embodiment. For example, the cloud environment 100 and the local environment 200 are connected to each other so as to be able to communicate with each other via the Internet or the like.

The construction processing server 10 is an example of a development environment construction system that constructs a development environment for software that controls a target device constructed by hardware. The development environment constructed by the construction processing server 10 includes a virtual device that is virtually constructed. In FIG. 1, a real device A300 is shown as the target device. The real device A300 is a device (physical device) constructed by hardware, and is, for example, a device mounted on a vehicle. Examples of devices mounted on a vehicle include an ECU (Electronic Control Unit) controlled by an in-vehicle device via a CAN (Controller Area Network) or Ethernet (registered trademark), or a touch screen display for an IVI (In Vehicle Infotainment).

For example, real device A300 is placed in a local environment 200 where a user 400 verifies real device A300 and the like. For example, clients 210 and 220 are provided in the local environment 200. Clients 210 and 220 are computers such as PCs (Personal Computers) installed in the local environment 200.

For example, assume that a development environment for multiple virtual devices that are virtually configured by emulating multiple physical devices, including real device A300, in the cloud environment 100 has already been created. However, there is a demand for a development environment in which a specific device out of the multiple virtual devices is used as a physical device. The construction processing server 10 is intended to meet such demands, and can create a development environment in which physical devices and virtual devices coexist.

For example, the construction processing server 10 is provided in the cloud environment 100. However, the construction processing server 10 does not have to be provided in the cloud environment 100, and may be provided in an environment capable of communicating with the cloud environment 100 and the local environment 200.

The construction processing server 10 includes an acquisition unit 11, a determination unit 12, a construction unit 13, a trial unit 14, and a presentation unit 15. The construction processing server 10 is a computer including a processor and a memory. The memory is a ROM (Read Only Memory) and a RAM (Random Access Memory), and can store a program executed by the processor. The acquisition unit 11, the determination unit 12, the construction unit 13, the trial unit 14, and the presentation unit 15 are realized by a processor that executes a program stored in the memory. The acquisition unit 11, the determination unit 12, the construction unit 13, the trial unit 14, and the presentation unit 15 may be arranged in one server (one housing), or may be distributed across multiple servers (multiple housings).

The acquisition unit 11 acquires development environment specification information, virtual device information, and construction capability information. The operation of the acquisition unit 11 and each piece of information will be described in detail later.

The determination unit 12 determines where the development environment will be built. The operation of the determination unit 12 will be described in detail later.

The construction unit 13 constructs a development environment in the determined construction destination. The operation of the construction unit 13 will be described in detail later.

The trial unit 14 attempts to determine whether software that controls the target device can be developed in the constructed development environment. The operation of the trial unit 14 will be described in detail later.

The presentation unit 15 presents the results of the trial performed by the trial unit 14. Details of the operation of the presentation unit 15 will be described later.

In the cloud environment 100, multiple pieces of virtual device information related to multiple virtual devices included in the development environment built in the cloud environment 100 are stored. The virtual device information includes parameters that are required when using the virtual device, and the parameters are managed in a table or the like. As an example of multiple pieces of virtual device information, virtual device A information 30a related to virtual device A configured virtually by emulating real device A300 as software, and virtual device B information 30b related to virtual device B configured virtually by emulating real device B (not shown) as software are shown here.

Virtual device A information 30a includes device control software specification information 31, virtual IF setting information 32, virtual device software specification information 33, response performance requirement information 34, and virtual device setting information 35 for virtual device A. Here, the description focuses on virtual device A for real device A300, but this information exists for each real device. In other words, in addition to this, virtual device information corresponding to various real devices may be stored in the cloud environment 100.

The device control software specification information 31 is information that indicates the content or acquisition source of the software (device control software) that controls the virtual device A included in the development environment built in the cloud environment 100. For example, the device control software specification information 31 includes access information for a git repository or information that indicates which code state in the repository. By using the device control software specification information 31, it is possible to use the software that controls the virtual device A.

The virtual IF setting information 32 is setting information related to the setting of the virtual interface, which is an input/output interface for virtual device A when controlling virtual device A from the above software (device control software). For example, the virtual IF setting information 32 includes access destination information for virtual device A. Note that by changing the virtual IF setting information 32, the access destination can be changed to real device A300, and real device A300 can be controlled from the device control software.

The virtual device software specification information 33 is information indicating the contents or acquisition source of the software indicating the virtual device A. For example, the virtual device software specification information 33 includes access information for a git repository or information indicating which code state in the repository. By using the virtual device software specification information 33, the virtual device A can be used.

The response performance requirement information 34 is information that indicates the responsiveness required when controlling virtual device A. For example, the response performance requirement information 34 includes the response time required when controlling virtual device A.

Virtual device setting information 35 includes resource information indicating the computational resources required to control virtual device A. For example, when virtual device A is realized by an HV or the like, the resource information includes computational resources such as the number of CPU cores and memory amount required.

Virtual device B information 30b also includes information about virtual device B similar to that of virtual device A information 30a. For example, by replacing virtual device A with virtual device B in the above explanation, the explanation of virtual device B information 30b is obtained. The same applies to the other virtual device information.

For example, the user 400 inputs development environment specification information 20 indicating the specifications of a development environment in which physical devices and virtual devices are mixed into, for example, a device (such as a PC or a mobile terminal) communicatively connected to the cloud environment 100 or the local environment 200. Alternatively, the development environment specification information 20 may be stored in a device in the cloud environment 100 or the local environment 200. For example, the development environment specification information 20 includes information indicating which physical device is to be specified (here, information indicating that real device A is to be specified) and information indicating the location of real device A300. The information indicating the location of real device A300 includes, for example, the location where real device A300 exists (here, the local environment 200) and the connected device (here, the client 210).

In addition, devices that are candidates for building a development environment store construction capability information indicating the construction capability of the development environment. For example, client 210 stores construction capability information 40a, client 220 stores construction capability information 40b, and cloud environment 100 stores construction capability information 40c.

For example, the construction capability information 40a includes information indicating whether a development environment can be constructed in the client 210, or information indicating the storage capacity of the storage owned by the client 210. The information indicating whether a development environment can be constructed may be information indicating whether the client 210 includes an HV, and if the client 210 does not include an HV, construction of a development environment may be impossible in the client 210. Furthermore, the information indicating whether a development environment can be constructed may be information indicating whether the client 210 is permitted to construct a development environment, and if the client 210 is not permitted to construct a development environment, construction of a development environment may be impossible in the client 210. The information indicating the storage capacity may be information indicating the remaining storage capacity of the storage owned by the client 210.

For example, the construction capability information 40b includes information indicating whether a development environment can be constructed in the client 220, or information indicating the storage capacity of the storage owned by the client 220. The information indicating whether a development environment can be constructed may be information indicating whether the client 220 includes an HV, and if the client 220 does not include an HV, construction of a development environment in the client 220 may be impossible. The information indicating whether a development environment can be constructed may be information indicating whether the client 220 is permitted to construct a development environment, and if the client 220 is not permitted to construct a development environment, construction of a development environment in the client 220 may be impossible. The information indicating the storage capacity may be information indicating the remaining storage capacity of the storage owned by the client 220.

For example, the construction capability information 40c includes information indicating whether a development environment can be constructed in the cloud environment 100, or information indicating the storage capacity of the storage that the cloud environment 100 has. The information indicating whether a development environment can be constructed may be information indicating whether the cloud environment 100 is permitted to construct a development environment, and if the cloud environment 100 is not permitted to construct a development environment, it may be impossible to construct a development environment in the cloud environment 100. The information indicating the storage capacity may be information indicating the remaining storage capacity of the storage that the cloud environment 100 has.

Next, the details of the operation of the construction processing server 10 will be explained using Figure 2.

Figure 2 is a flowchart showing an example of the operation of a development environment construction system (construction processing server 10) according to an embodiment.

First, the acquisition unit 11 acquires development environment specification information 20 indicating the specifications of the development environment, virtual device information regarding virtual devices (e.g., virtual device A information 30a and virtual device B information 30b, etc.), and construction capability information indicating the construction capability of the development environment in the candidate construction destination of the development environment (e.g., construction capability information 40a to 40c, etc.) (step S11). The acquisition unit 11 acquires this information from the cloud environment 100 or the local environment 200, but the source from which this information is acquired is not limited to the cloud environment 100 or the local environment 200. For example, this information does not have to be stored in the cloud environment 100 or the local environment 200, and the acquisition unit 11 may acquire this information from an environment other than the cloud environment 100 or the local environment 200.

Next, the determination unit 12 determines the construction destination of the development environment based on the development environment specification information 20, the virtual device information, and the construction capability information (step S12). For example, the determination unit 12 may determine either the cloud environment 100 or the local environment 200 as the construction destination of the development environment, and may further determine a specific device provided in the local environment 200 as the construction destination of the development environment.

For example, the determination unit 12 may determine the construction destination based on conditions related to the development environment specification information 20, the virtual device information, and the construction capability information. For example, the determination unit 12 may determine the construction destination based on conditions related to the development environment specification information 20, such as the location of the target device, the responsiveness and computational resource conditions required when controlling each virtual device (virtual device A, B, ...), the conditions for whether or not the development environment can be constructed in the candidate construction destination for the development environment, and the storage capacity conditions in the candidate construction destination for the development environment.

Specifically, for the condition of the location of the target device, the equipment to which the target device is connected, or the equipment in the LAN (Local Area Network) to which the equipment is connected, is likely to be selected as the construction destination. For the condition of responsiveness required when controlling each virtual device (virtual device A, B, ...), the equipment having the performance to realize the responsiveness is likely to be selected as the construction destination. For the condition of the computational resources required when controlling each virtual device, the equipment having the performance (number of CPU cores, remaining storage capacity, etc.) to satisfy the computational resources is likely to be selected as the construction destination. For the condition of whether the development environment can be constructed in the candidate construction destination of the development environment, the equipment capable of constructing the development environment is likely to be selected as the construction destination. For the condition of the storage capacity in the candidate construction destination of the development environment, the equipment having the required storage capacity is likely to be selected as the construction destination.

The user 400 may specify the destination where the development environment is to be built, and the determination unit 12 may determine that the development environment is to be built at the destination specified by the user 400.

The construction processing server 10 may also be provided with an output unit (not shown) that outputs information indicating the determined construction destination. This allows the user 400 to confirm the determined construction destination.

Next, the construction unit 13 constructs a development environment in the determined construction destination by changing the virtual IF setting information 32 (step S13). For example, the virtual IF setting information 32 is changed from a virtual interface setting for a virtual device (e.g., virtual device A) to a virtual interface setting for a target device (e.g., real device A300). This makes it possible to control the target device by software that controls the virtual device. By changing the virtual IF setting information 32, when a development environment is constructed in the determined construction destination, the target device is in a controllable state, so that a development environment can be automatically constructed in the determined construction destination. In other words, when a development environment is constructed in the determined construction destination, manual change of the virtual IF setting information 32 is not required.

Then, the trial unit 14 tries whether or not software that controls the target device can be developed in the constructed development environment (step S14), and the presentation unit 15 presents the result of the trial (step S15). For example, the presentation unit 15 presents, as the result of the trial, whether or not development is possible, in other words, whether or not the construction of the development environment was successful, and may also present the construction destination if successful. For example, if unsuccessful, the processes from step S12 to step S15 may be repeated until success is achieved.

Note that, if multiple construction destinations are determined in step S12, the user 400 may select which construction destination the development environment will be built in.

In addition, a priority order may be assigned to the candidate construction destinations for the development environment, and in steps S12 to S15, the construction destinations may be determined in order of priority, and the development environment may be constructed, attempted, and the results of the trials may be presented. For example, if construction of the development environment at a construction destination with a high priority fails, the construction destination with the next highest priority may be determined, and the development environment may be constructed, attempted, and the results of the trials may be presented.

Here, we will explain examples of information contained in the development environment specification information 20, virtual device information, and construction capability information, as well as examples of the operation of the construction processing server 10, when a client 210 is presented as the destination for constructing the development environment and when a cloud environment 100 is presented.

First, we will explain the case where client 210 is presented as the destination for building the development environment.

For example, the development environment specification information 20 includes the global IP address of the local environment 200 as information on the location where the actual device A300 exists, and the local IP address of the client 210 and the local IP address of the client 220 as information on the client linked to the local environment 200. Note that the development environment specification information 20 also includes information similar to that of the local environment 200 for local environments not shown.

In addition, for example, the development environment specification information 20 includes, as information about a physical device (actual device), a combination of information indicating the type of actual device A300 (e.g., storage) and information indicating the connected client (e.g., client 210).

For example, virtual device A information 30a includes a combination of information indicating the type of device (e.g., storage), virtual device setting information 35 (e.g., required storage capacity is 10 GB or more), and response performance requirement information 34 (e.g., within 100 ms).

For example, the construction capability information 40a includes information indicating that the client 210 can construct a development environment (information indicating that there is an HV) and information indicating that the remaining storage capacity is 100 GB. For example, the construction capability information 40b includes information indicating that the client 220 cannot construct a development environment (information indicating that there is no HV) and information indicating that the remaining storage capacity is 100 GB. For example, the construction capability information 40c includes information indicating that the client environment 100 can construct a development environment (information indicating that there is an HV) and information indicating that the remaining storage capacity is 1 TB.

When the development environment specification information 20, virtual device information, and construction capability information contain the above information, the construction processing server 10 operates as follows.

The determination unit 12 checks the virtual device A information 30a corresponding to the real device A300 based on information indicating the type of the real device A300 specified in the information on the physical device (real device), and confirms that the required storage capacity is 10 GB or more and the required responsiveness is within 100 ms. The determination unit 12 determines that the client 220 is inappropriate as a construction destination based on the construction capability information 40b. The determination unit 12 determines that both the client 210 and the cloud environment 100 have sufficient remaining storage capacity based on the construction capability information 40a and 40c.

The construction unit 13 constructs a development environment in the client 210 and the cloud environment 100 based on information on the locations where the client 210 and the cloud environment 100 are located. For example, the construction unit 13 may access an IP address and issue a construction instruction, or software that communicates with the cloud to obtain data may be provided for each location where the client 210 and the cloud environment 100 are located.

The trial unit 14 tries whether or not software can be developed in the development environments constructed in each of the client 210 and the cloud environment 100. Specifically, the trial unit 14 runs the development environments in each of the client 210 and the cloud environment 100, and checks whether the requirements indicated by the virtual device setting information 35 and the response performance requirement information 34 are satisfied. For example, assume that the response of the cloud environment 100 exceeds 100 ms. As a result, the cloud environment 100 is determined to be inappropriate as a location for constructing a development environment, and the presentation unit 15 presents the client 210 as a result of the trial.

Next, we will explain the case where the cloud environment 100 is presented as the destination for building the development environment.

For example, the development environment specification information 20 includes the global IP address of the local environment 200 as information on the location where the actual device A300 exists, and the local IP address of the client 210 and the local IP address of the client 220 as information on the client linked to the local environment 200. Note that the development environment specification information 20 also includes information similar to that of the local environment 200 for local environments not shown.

For example, the development environment specification information 20 includes, as information about a physical device (actual device), a combination of information indicating the type of actual device A300 (e.g., a display) and information indicating the connected client (e.g., client 210).

For example, virtual device A information 30a includes a combination of information indicating the type of device (e.g., a display), virtual device setting information 35 (e.g., the number of allocated CPU cores is 4 or more), and response performance requirement information 34 (e.g., within 1 second).

For example, the construction capability information 40a includes information indicating that the client 210 can construct a development environment (information indicating that there is an HV) and information indicating that the remaining storage capacity is 100 GB. For example, the construction capability information 40b includes information indicating that the client 220 cannot construct a development environment (information indicating that there is no HV) and information indicating that the remaining storage capacity is 100 GB. For example, the construction capability information 40c includes information indicating that the client environment 100 can construct a development environment (information indicating that there is an HV) and information indicating that the remaining storage capacity is 1 TB.

When the development environment specification information 20, virtual device information, and construction capability information contain the above information, the construction processing server 10 operates as follows.

The determination unit 12 checks the virtual device A information 30a corresponding to the real device A300 based on the information indicating the type of the real device A300 specified in the information on the physical device (real device), and confirms that the number of assigned CPU cores is 4 or more and that the required responsiveness is within 1 second. Based on the construction capability information 40b, the determination unit 12 determines that the client 220 is inappropriate as a construction destination.

The construction unit 13 constructs a development environment in the client 210 and the cloud environment 100 based on information on the locations where the client 210 and the cloud environment 100 are located. For example, the construction unit 13 may access an IP address and issue a construction instruction, or software that communicates with the cloud to obtain data may be provided for each location where the client 210 and the cloud environment 100 are located.

The trial unit 14 tries whether or not software can be developed in the development environments constructed in each of the client 210 and the cloud environment 100. Specifically, the trial unit 14 runs the development environments in each of the client 210 and the cloud environment 100, and checks whether the requirements indicated by the virtual device setting information 35 and the response performance requirement information 34 are satisfied. For example, assume that the client 210 is only able to be assigned two CPU cores. As a result, the client 210 is determined to be inappropriate as a location for constructing a development environment, and the presentation unit 15 presents the cloud environment 100 as a result of the trial.

Next, the case where the development environment is built in the local environment 200 will be explained using FIG. 3, and the case where the development environment is built in the cloud environment 100 will be explained using FIG. 4.

Figure 3 is a configuration diagram showing an example of a development environment 500 built in the local environment 200. For example, assume that the development environment 500 is built in the client 210 in the local environment 200. Figure 3 shows a development environment 510 for device A and a development environment 520 for device B.

The development environment 510 includes device A control software 511, virtual IF setting information for actual device A 512, virtual device A 513, and virtual device setting information 515.

The device A control software 511 is software indicated by the device control software specification information 31 included in the virtual device A information 30a shown in FIG. 1, and is software for controlling the real device A300. However, since the device A control software 511 is software developed for the virtual device A513, for example, the user 400 uses the development environment 500 to improve the device A control software 511 in accordance with the real device A300.

The virtual IF setting information 512 for real device A is the virtual IF setting information 32 included in the virtual device A information 30a shown in FIG. 1, which has been changed to the setting of a virtual interface for real device A300. Since the virtual IF setting information 512 for real device A is the setting of a virtual interface for real device A300, it is possible to control real device A300 by device A control software 511.

Virtual device A513 is a virtual device indicated by virtual device software specification information 33 included in virtual device A information 30a shown in FIG. 1. Because development environment 510 is a development environment for software that controls real device A300, virtual device A513 does not need to be used. Alternatively, virtual device A513 may also be used in development environment 510 depending on the situation.

The virtual device setting information 515 is the virtual device setting information 35 included in the virtual device A information 30a shown in FIG. 1.

The development environment 520 includes device B control software 521, virtual IF setting information for virtual device B 522, virtual device B 523, and virtual device setting information 525.

The device B control software 521 is software indicated by the device control software specification information 31 included in the virtual device B information 30b shown in FIG. 1, and is software for controlling the virtual device B 523.

The virtual IF setting information 522 for virtual device B is the virtual IF setting information 32 included in the virtual device B information 30b shown in FIG. 1, which is the setting of the virtual interface for virtual device B 523. Since the virtual IF setting information 522 for virtual device B is the setting of the virtual interface for virtual device B 523, the virtual device B 523 can be controlled by the device B control software 521.

Virtual device B523 is a virtual device indicated by virtual device software specification information 33 included in virtual device B information 30b shown in FIG. 1. Since development environment 520 is a development environment for software that controls virtual device B523, virtual device B523 is used. In this way, development environment 500 includes a mixture of development environment 510 related to real device A300 and development environment 520 related to virtual device B523.

The virtual device setting information 525 is the virtual device setting information 35 included in the virtual device B information 30b shown in FIG. 1. For example, the client 210 includes an HV, which determines the number of CPU cores allocated to the development environment 520 according to the virtual device setting information 525. However, it may be found after the development environment 500 is constructed that the CPU performance is low with this number of CPU cores allocated. In such a case, the virtual device setting information 525 may be changed so that the CPU performance is sufficient, that is, the number of CPU cores allocated in the virtual device setting information 525 may be increased. For example, when the next development environment is constructed (for example, when the development environment for the real device A is constructed, or when the development environment for another real device is constructed), the changes in the virtual device setting information 525 (virtual device setting information 35) may be presented to the user 400 and applied.

Figure 4 is a configuration diagram showing an example of a development environment 600 built in the cloud environment 100. Figure 4 shows a development environment 610 for device A and a development environment 620 for device B.

The development environment 610 includes device A control software 611, virtual IF setting information for actual device A 612, virtual device A 613, and virtual device setting information 615.

The device A control software 611 is software indicated by the device control software specification information 31 included in the virtual device A information 30a shown in FIG. 1, and is software for controlling the actual device A300. However, since the device A control software 611 is software developed for the virtual device A613, for example, the user 400 uses the development environment 600 to improve the device A control software 611 in accordance with the actual device A300.

The virtual IF setting information 612 for real device A is the virtual IF setting information 32 included in the virtual device A information 30a shown in FIG. 1, which has been changed to the setting of the virtual interface for the real device A300. Since the virtual IF setting information 612 for real device A is the setting of the virtual interface for the real device A300, the real device A300 can be controlled by the device A control software 611. For example, the virtual IF setting information 612 for real device A includes access information to the real device A300 provided in the local environment 200 (for example, access information to the real device A300 connected to the client 210 provided in the local environment 200 connected to the cloud environment 100 via the Internet, etc.).

Virtual device A613 is a virtual device indicated by virtual device software specification information 33 included in virtual device A information 30a shown in FIG. 1. Since development environment 610 is a development environment for software that controls real device A300, virtual device A613 does not need to be used. Alternatively, virtual device A613 may also be used in development environment 610 depending on the situation.

The virtual device setting information 615 is the virtual device setting information 35 included in the virtual device A information 30a shown in FIG. 1.

The development environment 620 includes device B control software 621, virtual IF setting information for virtual device B 622, virtual device B 623, and virtual device setting information 625.

The device B control software 621 is software indicated by the device control software specification information 31 included in the virtual device B information 30b shown in FIG. 1, and is software for controlling the virtual device B 623.

The virtual IF setting information 622 for virtual device B is the virtual IF setting information 32 included in the virtual device B information 30b shown in FIG. 1, which is the setting of the virtual interface for virtual device B 623. Since the virtual IF setting information 622 for virtual device B is the setting of the virtual interface for virtual device B 623, the virtual device B 623 can be controlled by the device B control software 621.

Virtual device B623 is a virtual device indicated by virtual device software specification information 33 included in virtual device B information 30b shown in FIG. 1. Since development environment 620 is a development environment for software that controls virtual device B623, virtual device B623 is used. In this way, development environment 600 includes a mixture of development environment 610 related to real device A300 and development environment 620 related to virtual device B623.

The virtual device setting information 625 is the virtual device setting information 35 included in the virtual device B information 30b shown in FIG. 1. For example, the cloud environment 100 includes an HV, which determines the number of CPU cores allocated to the development environment 620 according to the virtual device setting information 625. However, it may be found after the development environment 600 is constructed that the CPU performance is low with this number of CPU cores allocated. In such a case, the virtual device setting information 625 may be changed so that the CPU performance is sufficient, that is, the number of CPU cores allocated in the virtual device setting information 625 may be increased. For example, when the next development environment is constructed (for example, when the development environment for the real device A is constructed, or when the development environment for another real device is constructed), the changes in the virtual device setting information 625 (virtual device setting information 35) may be presented to the user 400 and applied.

(summary)
The construction processing server 10 is a development environment construction system that constructs a development environment for software that controls a target device (actual device A300) configured in hardware, and the development environment includes a virtually constructed virtual device. The construction processing server 10 includes an acquisition unit 11 that acquires development environment specification information 20 indicating the specifications of the development environment, virtual device information related to the virtual device, and construction capability information indicating the construction capability of the development environment in a candidate destination for the construction of the development environment, and a determination unit 12 that determines the destination for the development environment based on the development environment specification information 20, the virtual device information, and the construction capability information.

This makes it possible to determine the optimal construction destination based on the specifications of the development environment in which the target device (physical device) and virtual devices coexist, information about the virtual devices included in the development environment, and the construction capabilities of the development environment candidate construction destinations for the development environment. Therefore, a development environment in which physical devices and virtual devices coexist can be constructed in the determined construction destination, improving development efficiency. For example, while construction of a development environment takes time, the present disclosure automates the determination of the construction destination, improving development efficiency.

For example, the determination unit 12 may determine the construction destination based on conditions related to the development environment specification information 20, virtual device information, and construction capability information.

For example, the development environment specification information 20 may include information indicating the location of the target device.

This makes it possible to determine the optimal location to build the device based on information such as the location of the target device and the connected equipment.

For example, the virtual device information may include response performance requirement information 34 indicating the responsiveness required when controlling the virtual device, or resource information indicating the computing resources required when controlling the virtual device.

This makes it possible to determine the optimal construction location that satisfies the conditions, depending on the responsiveness required when controlling the virtual device or the computing resources required when controlling the virtual device.

For example, the construction capability information may include information indicating whether a development environment can be constructed or information indicating storage capacity.

This makes it possible to determine a construction destination where the development environment (e.g., a virtual device included in the development environment) can function properly, depending on whether the development environment can be constructed at the candidate construction destinations or on the storage capacity.

For example, the virtual device information may include virtual IF setting information 32 regarding the settings of a virtual interface, which is an input/output interface for the virtual device, and the construction processing server 10 may further include a construction unit 13 that constructs a development environment at the determined construction destination by changing the virtual IF setting information 32.

This allows the development environment to be automatically built in the determined build destination by changing the input/output interface settings for the virtual device to the input/output interface for the target device.

For example, the construction processing server 10 may further include a trial unit 14 that attempts to determine whether software that controls the target device can be developed in the constructed development environment, and a presentation unit 15 that presents the results of the trial.

This allows you to check whether the development environment built at the selected location is functioning correctly.

For example, candidates for building a development environment may include HV.

This means that HV makes it easier to build and replicate development environments.

(Other embodiments)
As described above, the embodiment has been described as an example of the technology according to the present disclosure. However, the technology according to the present disclosure is not limited to this, and can be applied to an embodiment in which appropriate changes, substitutions, additions, omissions, etc. are made. For example, the following modified examples are also included in one embodiment of the present disclosure.

For example, in the early stages of development of the target device, all functions of the target device may not be complete, so the presentation unit 15 may present the differences between the functions supported by the target device and the functions supported by the virtual device.

For example, if it is not possible to create a development environment that includes a mixture of target devices and virtual devices, a development environment that includes a virtual device that corresponds to the target device may be created with the consent of user 400.

For example, before a development environment is built in the determined build destination, the user 400 may be asked whether it is OK to build a development environment in the determined build destination.

The present disclosure can be realized not only as a development environment construction system, but also as a development environment construction method including steps (processing) performed by each component that constitutes the development environment construction system.

The development environment construction method is executed by a development environment construction system that constructs a development environment for software that controls a target device configured with hardware, and the development environment includes a virtually configured virtual device. As shown in FIG. 2, the development environment construction method includes an acquisition step (step S11) of acquiring development environment specification information indicating the specifications of the development environment, virtual device information regarding the virtual device, and construction capability information indicating the construction capability of the development environment in a candidate destination for the development environment, and a determination step (step S12) of determining the destination for the development environment based on the development environment specification information, virtual device information, and construction capability information.

For example, the steps in the development environment construction method may be executed by a computer (computer system). The present disclosure can be realized as a program for causing a computer to execute the steps included in the development environment construction method.

Furthermore, the present disclosure can be realized as a non-transitory computer-readable recording medium, such as a CD-ROM on which the program is recorded.

For example, when the present disclosure is realized as a program (software), each step is performed by executing the program using hardware resources such as a computer's CPU, memory, and input/output circuits. In other words, each step is performed by the CPU acquiring data from memory or input/output circuits, etc., performing calculations, and outputting the results of the calculations to memory or input/output circuits, etc.

Furthermore, each component included in the development environment construction system of the above embodiment may be realized as a dedicated or general-purpose circuit.

In addition, each component included in the development environment construction system of the above embodiment may be realized as an LSI (Large Scale Integration), which is an integrated circuit (IC).

In addition, the integrated circuit is not limited to an LSI, and may be realized by a dedicated circuit or a general-purpose processor. A programmable FPGA (Field Programmable Gate Array) or a reconfigurable processor in which the connections and settings of circuit cells inside the LSI can be reconfigured may be used.

Furthermore, if an integrated circuit technology that can replace LSIs emerges due to advances in semiconductor technology or other derived technologies, that technology may of course be used to integrate the various components included in the development environment construction system.

In addition, this disclosure also includes forms obtained by applying various modifications to the embodiments that would come to mind by a person skilled in the art, and forms realized by arbitrarily combining the components and functions of each embodiment within the scope of the spirit of this disclosure.

This disclosure can be applied, for example, to a system for building a development environment for software that controls devices installed in a vehicle.
