Abstract
There are contained the step of forming voltage waveform information by calculating a voltage waveform of each instance of a semiconductor integrated circuit at a power-supply terminal based on circuit information and analyzing the voltage waveform of each instance, the step of forming voltage abstraction information by abstracting the voltage waveform information, and the step of calculating a delay value of the instance based on the voltage abstraction information.
