Patent ID: 7941773

Claim:
A simulation system for performing simulation of an operation of a circuit, the simulation system comprising: a particular signal substituting section for making, in the simulation, an output signal of a first flipflop or an input signal of a second flipflop be a particular signal indicating neither high level nor low level during a period which is 1 cycle shorter than a specified clock cycle number of a multicycle path which has been specified in advance; and an output section for outputting information corresponding to whether or not a signal at an output terminal of the second flipflop or at part of the circuit located in a subsequent stage of the output terminal of the second flipflop, which has been specified in advance, is made to be the particular signal, wherein said simulation is based on circuit information indicating a circuit configuration of the circuit including the first flipflop and the second flipflop to which the output signal of the first flipflop is input without passing any other flipflop therebetween.
