PROBLEM TO BE SOLVED: To complete wiring design satisfying wiring restrictions in a short period of time by presenting a rough wiring from the floor plan stage concerning a wiring board requiring a wide variety of wiring restrictions while evaluating the degree of wiring congestion or the like, in a wiring design support system. SOLUTION: After inputting logical wire connection information for wiring components and signal group information for handling as a signal group collecting up wiring, the signal group is handled as a wiring unit for pathway search, the signal groups are divided sequentially, and an optimal route is searched out by disposing each divided signal group as close as possible with each other. In addition, the route search is performed by evaluating the layout of components and the degree of wiring congestion when dividing the signal groups. COPYRIGHT: (C)2005,JPO&NCIPI
