DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a circuit wiring connection device characterized in that a certain circuit block and another circuit block are arbitrarily combined and connected.

Conventionally, in connection of elements of electronic components, wiring connections of printed circuit boards, etc., the arrangement and wiring are generally done according to the wiring diagram determined by the specifications, and the arrangement and wiring are fixed in one way. It becomes something.

FIG. 1 shows an example of wiring between terminals of one circuit block and another circuit block. In the same figure,
Reference numeral 1 denotes a first circuit block, which is an integrated circuit, other electronic component elements, a printed circuit board, or the like. 2 is a terminal of this first circuit block 1.

Reference numeral 5 denotes a second circuit block, which is similar to the first circuit block 1.

4 is a terminal of the second circuit block 5.

Reference numeral 3 denotes an inter-block wiring connecting the terminal 2 of the first circuit block 1 and the terminal 4 of the second circuit block 5, which is a wiring of a printed circuit board, a lead wire cable, or the like.

As for the wiring connection method of the circuit, there is also a case where wiring is connected from one circuit block to several circuit blocks, but this will be explained below based on the configuration example in the case of FIG. 1.

Sending necessary electrical signals from the first circuit block 1,
Alternatively, when transmitting or receiving an electric signal from the second circuit block 5, the terminal 2 of the first circuit block 1 and the terminal 4 of the second circuit block 5 are connected by the inter-block wiring 3. .

For example, the first terminal 2-1 of the terminals 2 of the first circuit block 1 is connected to the first terminal 4-1 of the terminals 4 of the second circuit block 5, and the second terminal 2-2 is connected to the terminal 4 of the terminals 4 of the second circuit block 5. th terminal 4
-5, and so on. When connecting each terminal in this way, a wiring pattern is created on the board using printed wiring and the ends of each pattern are soldered, or they are soldered directly using lead wires. In the conventional wiring connection method as described above, once one wiring pattern is determined,
Printed wiring boards and the like with predetermined wiring patterns are suitable for mass production, but when it is desired to change the wiring, it is necessary to recreate the board with a wiring pattern that meets the specifications.

At this time, the board before the change may become unusable, resulting in a total loss, and in the case of soldering, etc., wiring must be performed once again. Also, if you want to change the pin number of the socket, etc., you will need to rewire it each time to match the pin number of the electronic component. The present invention has been made in order to eliminate the drawbacks of the conventional devices as described above, and includes a wiring control circuit having a gate array section and a gate control section between the circuit blocks for transmitting and receiving, and the wiring control circuit having a gate array section and a gate control section. A wiring connection device for a circuit that allows wiring to be arbitrarily connected between each terminal by arbitrarily controlling the opening/closing state of the gate of the circuit, or a wiring connection device for a circuit that is designed to enable wiring within a certain specification range. By providing a wiring control circuit such as the one shown in FIG. It is an object of the present invention to provide a circuit wiring connection device that can be easily connected.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 shows a circuit wiring connection device according to an embodiment of the present invention, in which numerals 1, 2, 4, and 5 are the same circuit blocks and connection terminals as in FIG. 1. 10 is a wiring control circuit, 11 is one terminal of the wiring control circuit 10, and 12 is a wiring control circuit 10.
The wiring control circuit 10 has a gate array section (not shown) consisting of a plurality of gates which are provided between the terminals 11 and 12 and whose opening/closing states can be arbitrarily set.

Further, 13 is a first wiring between the first circuit block 1 and the wiring control circuit 10, 14 is a second wiring between the wiring control circuit 10 and the second circuit block 5, and 15 is a wiring control circuit when wiring is to be performed. This is an input terminal for a wiring control signal to send the wiring pattern information necessary for 10 to the gate array section, and this constitutes a part of the gate control section that controls the opening/closing state of each gate in the gate array section according to external input. It is something to do.
Further, FIG. 3 shows an example of a processing device for processing information on a wiring pattern in the wiring control circuit 10 of FIG. 2. In FIG.

In the figure, the same symbols as in FIG. 2 indicate the same parts, 21 is an input device for inputting commands, 22 is an input interface, 23 is a central processing unit, and 24 is a ROM
adOnlyMemOry), 25 is RAM (Rand
OmAccessMemOry), 26 is a wiring control circuit interface section. Next, the operation shown in FIG. 2 will be explained. As shown in Fig. 2, two circuit block 1,
5, the wiring control circuit 10 is inserted between these circuit blocks to connect each terminal. In the wiring control circuit 10, connect one terminal to CX
l, CX2, CX3,..., the other terminal Cy,, Cy
2, Cy3,... For example, the terminals 2-1, 2-2, 2-3, . . . of the first circuit block 1 are the terminals CXl, CX2, CX3, .
・Assume that it is wired to . Similarly, each of the other terminals Cyl, Cy2, Cy3, . . . of the wiring control circuit 10 is also wired to each terminal 4-1, 4-2, 4-3, . . . of the second circuit block 5. . Information corresponding to the wiring pattern is sent between each terminal 11 and 12 of the wiring control circuit 10 from the wiring control signal input terminal 15 to control the gate connection. For example, through the input terminal 15, the terminals CXl and Cyl
, CX2 and Cy2, . . . , terminals 2-1 and 4-1, and terminals 2-2 and 4-2 are connected. When changing these connections, the gate connections can be changed by supplying connection pattern information to be changed from the wiring control signal input terminal 15.

For example, if the above wiring pattern is connected to terminals CXl and Cy2,C
If you change X2 and Cyl, terminals 2-1 and 4-2
, 2-2 and 4-1. Even if the connection terminal is changed, the connection can be changed in the same way. If such wiring connections are frequently required, the connections can be quickly changed by using a computer device as shown in FIG.

Moreover, without using such a computer device, the circuit block 1,
When only the wiring control circuit 10 is used for the wiring connection between the wirings 5 and 5, a programmable ROM in which the gate opening/closing pattern of the gate array section is written in a non-volatile manner can be used as the wiring control circuit 10. In this case, in order to change the connection as described above, it is necessary to
It suffices to use an electrically rewritable element such as ``ableReadOnlyMe-MOry''.
All the contents of M may be erased by ultraviolet rays, and then writing may be performed again via the wiring control signal input terminal 15 so that the opening/closing states of the gates in the gate arrangement section become a desired pattern. Next, a description will be given of the operation shown in FIG. 3 in which a computer device is used to create or change a wiring pattern.

When commands and data necessary for a wiring pattern are inputted from the input device 21, the commands are analyzed and data processed by the CPU 23, RAM 25, etc. according to the processing procedure of the program stored in the ROM 24 via the input interface 22. The data is sent to the wiring control circuit 10 via the gate control interface section 26 as wiring pattern information data. Therefore, the connection between the first circuit block 1 and the second circuit block 5 can be arbitrarily specified using this connection pattern information. in this case,
If the gate pattern information of the wiring control circuit 10 is stored using a temporary storage memory method, wiring connections can be changed immediately. Next, a specific example of connection by the gate arrangement section will be shown based on FIGS. 4 and 5.

FIG. 4 shows an example in which each terminal group of the wiring control circuit has three terminals, where one terminal is CX1, CX2, and CX3, and the other terminal is Cyl, Cy2, and Cy3.

Further, the gate numbers of the gate array at this time are assumed to be G1 to Q. FIG. 5 is an example of a connection code table, showing the state of each gate and the state of connection between terminals. In the figure, when each gate state is 611, the connection between the terminals is in a conductive state, and
Related paths are combined. Also, when each gate is ``0'', the connection between the terminals is non-conductive, and the related paths are not coupled.For example, if gates G3, G5, and G7 are 1'' and the other gates are 0'', as shown in Figure 4. , the terminals CXl and Cy
Each terminal is connected like 1, CX2 and Cy2, and CX3 and Cy3. In FIG. 3, gate state codes and terminal connection combination codes relating to connections between terminals are created and stored in the RAM 25 in order from memory addresses as a connection code table as shown in FIG. When necessary connection data is designated from the input device 21 in FIG. 3, the connection data is processed by the CPU 23 according to the program in the ROM 24 and replaced as one combination code. The code is searched in the memory code table previously stored in the RAM 25 as described above, and if a matching code is found, the gate state code corresponding to that code is accessed from the RAM 25, and those data are used for wiring control. By sending the signal to the wiring control circuit 10 via the interface section 26, a necessary combination of connections can be provided. As is clear from the above description, in such a circuit wiring connection device, wiring connections can be changed programmably using a wiring control circuit.

Further, wiring connections can be changed by specifying wiring data without requiring replacement of soldering as in the conventional case. In the above embodiment, an example was explained in which two circuit blocks are connected using one wiring control circuit, but it is also possible to connect a plurality of circuit blocks using two or more wiring control circuits. It is.

It is also possible to connect several circuit blocks with one wiring control circuit. Furthermore, the present invention can be used not only to change the connections between circuit block elements and printed wiring, but also to automatically change the wiring of switchboxes, and to change the connections of test equipment.

As described above, according to the present invention, by using a wiring control circuit, it is possible to arbitrarily change the wiring between the terminals of a plurality of circuit blocks, and once a program that satisfies the change specifications is created, it is possible to change the wiring in a short time. Wiring changes can be made to Furthermore, it is also possible to implement a series of circuit devices with different specifications on one board.
