PURPOSE:To facilitate the mounting design of a high density printed circuit board having high wiring accommodation capable of determining an optimum wiring path in three dimensions while combinedly using various kinds of drilling systems by obtaining a position where a hole can be drilled without violating inhibit area information. CONSTITUTION:A drilling inhibit information preparation part 107 for each drilling system reads in information from a wiring pattern information file 104, pattern dimension for each drilling system/drilling range information of a wiring object section management table 112 and minimum conductor interval information, and prepares the drilling inhibit information for each drilling system of a wiring grid information table 113. A wiring inhibit information preparation part 108 reads in the information from the wiring pattern information file 104, the line information of the wiring object section management table 112 and the minimum conductor interval information, and prepares the wiring inhibit information of the wiring grid information table 113. A wiring path search processing part 110 executes the wiring path search while referencing to and updating a seach base point information table 115. |
