PROGRAM FOR DESIGNING ELECTRONIC CIRCUIT, METHOD FOR DESIGNING ELECTRONIC CIRCUIT AND DEVICE FOR DESIGNING ELECTRONIC CIRCUIT

摘要

A noise value concerning a part of all electronic circuits (cells) being designed is calculated, and, when the noise value exceeds a limit value, parameters of the electronic circuit (length of a parallel section, adjacent distance of the parallel section, and the like) are altered by a specified method such that the noise value becomes smaller than the limit value (convenient noise check). Timing of signal transmission is then analyzed for all electronic circuits, the noise value concerning all electronic circuits subjected to timing analysis is calculated, and the convenient noise check is performed when the noise value exceeds the limit value.
