Abstract
An information processing device includes a memory; and one or more processors which are coupled to the memory and configured to performs a process including verifying a quality of a signal waveform that is propagated through focused wiring on a substrate, and storing information which is used for the verification of the quality of the signal waveform, and wherein the verifying includes generating analysis models of a plurality of respective combinations of variations in a plurality of kinds of elements which have an influence on the quality of the signal waveform; calculating impulse-response-waveforms of the plurality of respective combinations using the generated analysis models; calculating the noise amount of the plurality of respective combinations based on the calculated impulse-response-waveforms; selecting a combination, in which the calculated noise amount is the largest, as a worst case in the plurality of combinations; and performing signal waveform-transition-analysis on the selected worst case.
