Abstract:
1. A wiring design assisting apparatus that assists in wiring design of wiring patterns formed in a printed circuit board having plural layers, the wiring design assisting apparatus comprising: a first database that stores attribute information and position information that indicate attributes and positions of the wiring patterns in a manner in which the attribute information and the position information are associated with the wiring patterns; a second database that stores position information and size information that indicate positions and sizes of pattern removed areas that exist in solid patterns provided in the printed circuit board; a third database that stores degradation degree information that indicates degradation degrees in signal characteristics in the wiring patterns with respect to positional relationships between the wiring patterns and the pattern removed areas, and sizes of the pattern removed areas; an input part that has the attribute information of the wiring pattern input thereto; a degradation degree process part that obtains the degradation degree in the signal characteristics in the wiring pattern corresponding to the attribute information that is input to the input part, based on the position information of the wiring pattern corresponding to the attribute information input to the input part, the position information and the size information of the pattern removed area, and the degradation degree information; and an extracting process part that extracts, for re-wiring, the wiring pattern that has the degradation degree equal to or more than a predetermined degree, from the wiring patterns for which degradation degrees have been obtained by the degradation degree process part.
