Abstract
An apparatus for effecting a logic circuit simulation based on logic circuit information concerning the logic circuit and input signal information concerning each of circuit elements constituting the logic circuit according to simulation control information and producing output signal information, and a method for producing a semiconductor device using the simulation approach. By determining an input side signal delay value and an output side signal delay value with respect to a circuit element which is a simulation object, comparing the determined delay values and, based on a result of the comparing, determining an output signal value of the simulation object circuit element, it is possible to effect a perfect simulation on a transistor level subordinate to a gate level in practical processing time without using a special computer.
