Integrated circuit simulator and integrated circuit simulation method

摘要

A simulator speedily simulates an integrated circuit. The simulator has a digital simulator for simulating a digital part of the integrated circuit in each of sections divided from a total simulation time, an analog simulator for simulating an analog part of the integrated circuit in each of the sections, and a controller for controlling the digital and analog simulators. The controller determines for each of the sections whether or not the analog part must be simulated in the section and omits the simulation of the analog part in the section if it is determined not to simulate the analog part in the section.
