METHOD, PROGRAM AND APPARATUS FOR AIDING WIRING DESIGN

PROBLEM TO BE SOLVED: To improve design accuracy of wiring routes of buses.SOLUTION: A computer executes: a wiring plan generation procedure for generating a wiring plan so that routes of a plurality of buses respectively represented by graphics may not cross with each other in a wiring area including one or more wiring layers; a validity determination procedure for verifying, in each bus, whether a wire of each belonging net of the bus can be drawn out from the inside of a component to which the bus is connected; and a wiring plan decision procedure for recording graphics indicating the belonging nets of buses confirmed that all the belonging nets can be drawn out by the validity determiner, in the wiring area: and, in respect to the buses confirmed by the validity determination procedure that at least part of the belonging nets can not be drawn out, reexecutes the wiring plan generation procedure.
