Abstract
A simulator for simulating operations of a logical circuit has as its object the provision of a simulator capable of detailed timing error checking without impairing the simulation executing speed. A timing check primitive adding circuit, based on circuit information indicating electronic devices and loop circuits selected for timing error checking, outputs circuit information with simulation control data for controlling the simulation of only the selected devices or selected loop circuits. A timing error detection circuit and a timing error cause analyzing circuit grasp changes in test pattern input and output signals of a selected device and perform detailed timing error checking.
