PROBLEM TO BE SOLVED: To generate a circuit model that enables circuit analysis considering variation in power supply voltage with higher accuracy in a shorter time.SOLUTION: A circuit model generation device comprises: generation means that generates delay variation information indicating a ratio of delay variation of an output signal to a variation amount of power supply voltage given to a pre-buffer unit in an input/output circuit; and storage processing means that stores the delay variation information in IBIS data as a circuit model concerning the input/output circuit. |
