*** Explanation of operation ***

In the following, processing after the verification conditions shown in FIG. 4 are set will be described.
Note that the processing procedure illustrated in FIG. 6 corresponds to an example of an information processing method and an information processing program.

  First, the first circuit comparison part extraction unit 1021 of the comparison target extraction unit 102 extracts a net connected to the first starting pin of the first starting part defined in the verification condition from the first net list. (Step S601).

Next, the first circuit comparison part extraction unit 1021 acquires component attribute information of the component (first connected component) connected to the net extracted in step S601 from the component database (hereinafter also referred to as component DB). (Step S602).
FIG. 5 shows an example of component attribute information.
The component attribute information includes a component ID and an attribute of the component.
The attributes shown in the component attribute information are, for example, a characteristic value such as a resistance value for a resistor and a capacitance value for a capacitor, a component model number, a package type, and the like.
By the processing in step S602, the component attribute information of the first connection component connected to the comparison target net of the first circuit is extracted.

  Next, the second circuit comparison part extraction unit 1022 of the comparison target extraction unit 102 extracts, from the second netlist, the net to which the second starting pin of the second starting part defined in the verification condition is connected. (Step S603).

Next, the second circuit comparison part extraction unit 1022 acquires component attribute information of the component (second connected component) connected to the net extracted in step S603 from the component database (step S604).
By the processing in step S604, the component attribute information of the second connection component connected to the comparison target net of the second circuit is extracted.

Next, the difference extraction unit 103 determines whether or not the first connection component and the second connection component are the same (S605).
More specifically, the connection component comparison unit 1031 compares the component attribute information extracted in step S602 with the component attribute information extracted in step S604, and the connection destination component pin comparison unit 1032 The list and the second netlist are collated, and the first connection component is connected to the net extracted in step S601 and the second connection component is connected to the net extracted in step S603. Compare with the connecting pin.
The difference extraction unit 103 determines whether or not the first connection component and the second connection component are the same from the matching status of the component attribute information and the matching status of the connection pins.
For example, the difference extraction unit 103 determines that the first connection component and the second connection component are the same if part of the item attribute information of the first connection component matches the component attribute information of the second connection component. It may be determined that the first connection component and the second connection component are the same only when a plurality of designated items or all items match.
Further, in order to determine that the first connection component and the second connection component are the same circuit, it is also necessary that the connection pins of the first connection component and the connection pins of the second connection component match. is there.
However, it is possible to verify that components having no polarity such as resistors and some capacitors are regarded as the same even if the connection pins are different by registering the components in the “component list without polarity”.
The difference extraction unit 103 determines that the comparison target portion is the same if the first connection component and the second connection component of the comparison target portion are all the same.
For example, when there are ten first connection parts, the part attribute information and connection pin names of the ten first connection parts are the same as the part attribute information and connection pin names of the ten second connection parts. If so, the comparison target portions of the first circuit and the second circuit are the same.

If the verification condition includes a pair of the first starting pin and the second starting pin that has not been verified yet (YES in S606), the processing from S601 is repeated.
If verification has already been completed for all starting pin pairs (NO in S606), the process ends.

  Next, the processing flow of FIG. 6 will be described using the examples of FIGS.

In the verification condition setting No: 1 in FIG. 4A, since the first starting pin is a pin called PINF of the component: IC10, the first circuit comparison part extracting unit 1021 is connected to the net to which this pin is connected. Is extracted from the first netlist (step S601).
Next, the first circuit comparison portion extraction unit 1021 acquires component attribute information of R10, which is a component connected to the net NETA, from the component DB (step S602).
Next, in the verification condition setting No. 1 of FIG. 4A, since the second starting pin is a pin called PINB of the component: IC50, the second circuit comparison part extracting unit 1022 determines that this pin is NETB, which is a net to be connected, is extracted from the second net list (step S603).
Next, the second circuit comparison part extraction unit 1022 acquires the component attribute information of R20, which is a component connected to the net NETB, from the component DB (step S604).
Next, the connected component comparison unit 1031 compares the component attribute information of R10 with the component attribute information of R20.
In the case of FIG. 5, the connection component comparison unit 1031 confirms that the component ID, the characteristic value 1, the characteristic value 2, and the model number are different, although the package and the manufacturer are the same.
In addition, the connection component comparison unit 1031 confirms that the connection pin that connects R10 to NETA is PINA, and the connection pin that connects R20 to NETB is also PINA.
As a result, the difference extraction unit 103 determines that R10 and R30 are not the same, for example.

When the verification by the difference extraction unit 103 is completed, the verification result display unit 104 displays the verification result.
For example, the verification result display unit 104 displays the first circuit and the comparison target portion of the first circuit on the display device 300 at the same time, thereby enabling visual recognition of the entire first circuit and the detected difference. To do.
In addition, there is a method of highlighting and highlighting a difference portion to make it clearer.
In the highlight display of the difference portion, when the same type of components are connected in the first circuit and the second circuit, but part of the component attribute information such as the characteristic value is different, the first circuit and the second circuit Highlight the part in both drawings.
For a component that exists in the first circuit but does not exist in the second circuit, the verification result display unit 104 highlights the component in the drawing of the first circuit.
A component that is not present in the first circuit but present in the second circuit highlights that component in the drawing of the second circuit.
FIG. 9 shows a screen display image by the verification result display unit 104.

The functional configuration of the information processing apparatus 100 is the same as that shown in FIG. 2, but in the present embodiment, the comparison target extraction unit 102 functions as a component extraction unit and also as a connection line extraction unit.
In the present embodiment, the comparison target extraction unit 102 is a component extraction unit, which is a first netlist (first net list) indicating connection relationships between a plurality of components included in the first circuit and a plurality of nets (connection lines). 1), for each net included in the first circuit, a component connected to the net is extracted as a first connection component.
In addition, the comparison target extraction unit 102 refers to a second net list (second connection relation information) indicating a connection relation between a plurality of components included in the second circuit and a plurality of nets (connection lines). Thus, for each net included in the second circuit, a component connected to the net is extracted as a second connection component.
Further, the comparison target extraction unit 102 extracts, as a connection line extraction unit, the first connection component that is the same as the second connection component extracted for the net for each net included in the second circuit. A net included in the first circuit whose ratio is greater than or equal to the threshold is extracted.
In addition, when extracting the net of the first circuit, the comparison target extraction unit 102 selects the first attribute from a plurality of component attribute information indicating attributes of a plurality of components included in the first circuit and the second circuit. The component attribute information of the first connection component and the component attribute information of the second connection component are acquired.
Then, the comparison target extraction unit 102 refers to the acquired component attribute information, and for each net included in the second circuit, the same first connection component as the second connection component extracted for the net A net included in the first circuit in which the ratio of the extracted is equal to or greater than the threshold is extracted.
In the present embodiment, the processing performed by the comparison target extraction unit 102 corresponds to an example of a component extraction step and a connection line extraction step.

*** Explanation of operation ***
Next, an operation example of the information processing apparatus 100 according to the present embodiment will be described with reference to FIG.
Note that the processing procedure illustrated in FIG. 8 corresponds to an example of an information processing method and an information processing program.

  First, the second circuit comparison part extraction unit 1022 acquires all nets as circuit parts to be compared from the second net list that is the net list of the second circuit (step S801).

  Next, the second circuit comparison part extraction unit 1022 extracts the second connection component connected to the net acquired in step S801 from the second net list, and also acquires component attribute information of the second connection component. Obtained from the component DB (step S802).

  Next, the first circuit comparison portion extraction unit 1021 acquires all nets from the first net list that is the net list of the first circuit (step S803).

  Next, the first circuit comparison part extraction unit 1021 extracts the first connection component connected to the net acquired in step S803 from the first net list, and also acquires component attribute information of the first connection component. Obtained from the component DB (step S804).

  Next, the comparison target extraction unit 102 selects one net among the nets of the second circuit extracted in step S801 (step S805).

  Next, the comparison target extraction unit 102 determines that the first connection component that is the same as the second connection component extracted in step S802 is extracted from the net selected in step S805 on the first threshold. If there is a circuit net, the net of the first circuit is extracted (step S806).

Next, the comparison target extraction unit 102 determines whether or not an unselected net exists in the second circuit (step S807). If there is an unselected net, the processing from step S805 is repeated.
If all nets have been selected, the verification described in the first embodiment is performed on the pair of the first circuit net extracted in step S806 and the second circuit net selected in step S805. (Step S808).
Specifically, the processing in step S605 in FIG. 6 is performed on the pair of the first circuit net and the second circuit net.

Next, a description of step S806 will be supplemented.
When a certain part in the second circuit is diverted from the first circuit, the circuit configuration is completely the same in the diverted part in the second circuit and the first circuit.
However, there is a possibility that a circuit configuration in which a part of the circuit configuration of the first circuit is changed due to a misuse in the definition of the second circuit is defined in the second circuit.
In the present embodiment, a second circuit including a circuit configuration in which a part of the circuit configuration of the first circuit is changed due to such misuse in the definition of the second circuit is detected.
For this reason, the comparison target extraction unit 102 according to the present embodiment also needs to specify a portion of a second circuit that is substantially the same as the first circuit but is partially different.
More specifically, the comparison target extraction unit 102 extracts the combination of the second connection components extracted for the net of the second circuit selected in step S805 and the net of the first circuit. When the ratio (matching rate) at which the combinations of the first connection parts match is equal to or greater than the threshold value, it is determined that the net of the second circuit is a diversion location from the net of the first circuit. In step S806, the net of the first circuit is extracted.
For example, when there are ten second connection parts of the net of the second circuit, nine of the second connection parts coincide with the first connection parts of the net of the first circuit. If it is, the coincidence rate is 90%.
In this case, if the threshold is 80%, this net of the first circuit is extracted.
However, when the coincidence rate is obtained by the above method, for example, many nets connecting resistors and resistors appear in the circuit, and thus there are cases where many matching candidates appear and cannot be accurately determined.
In such a case, try matching only for nets with a certain number of connected parts or more, that is, avoid verification for nets less than that, thereby narrowing down the target circuit and improving matching accuracy. Realize.
In addition, in order to respond to the case where a large number of parts are connected, such as a net such as a power supply or ground, but it is desired to exclude them from the target of difference verification, the net name specified by the user is subject to verification regardless of the above criteria. It may be outside.
Also, if the connected parts are not the same, but are similar, for example, a part where resistance parts having different resistance values are connected is counted as a matching part for 0.5 and reflected in the matching rate. Also good.
