The node data supplied to the node data storage means 1 is stored in the node data storage means 1 (step S1).

On the other hand, the pin assignment connection data as shown in FIG. 4 is created in advance and stored in the connection information storage means 2 (step S2).

Next, in steps S1 and S2, a process is performed to compare the pin assignment of the node data stored in the node data storage means 1 with the pin assignment of the pin assignment connection data stored in the connection information storage means 2. It is supplied to the means 3 (step S3).

The processing means 3 compares the pin assignment of the node data stored in the node data storage means 1 with the pin assignment of the pin assignment connection data stored in the connection information storage means 2 as described above. Are matched (for example, the pin assignment “E
33 and “E3” corresponding to the signal name “DATA1” in FIG.
