PROBLEM TO BE SOLVED: To improve the accuracy in analyzing the voltage drop of a semicon ductor integrated circuit. SOLUTION: The consumed current of one megacell 60 is divided into plural constant-current sources 64, and these plural constant-current sources 64 are equally allocated to a power source wiring 62 in the megacell to modelize the megacell 60. The modelized megacell 60 is applied as the megacell in the semiconductor integrated circuit, and then the voltage drop of the semiconductor integrated circuit is analyzed.
