Abstract
Noise related to a part of electronic circuits that are to be designed is computed. If the computed noise exceeds a limiting value, parameters of the electronic circuits are modified by using a predetermined method (simple noise check) so that the noise is less than or equal to the limiting value. Signal transmission timing is analyzed for all the electronic circuits, and noise related to all the electronic circuits whose signal transmission timing is analyzed is computed. If the noise exceeds the limiting value, the simple noise check is executed.
