PROBLEM TO BE SOLVED: To provide an input/output signal display system being a supporting tool for investigating an operation timing to be simulated by a simulator from the input/output signal of a digital circuit. SOLUTION: This input/output signal display system displays the effect of the change of a plurality of input signals on an output signal as an output signal waveform through the state of a digital circuit. In this case, it is possible to set conditions that should be satisfied for making the change of the input signal affect the output state, conditions that should be satisfied for making the circuit state affect the output signal and the conditions of the affecting timing. The circuit state is automatically changed according to the input signal, and the output signal is automatically changed and displayed according to the changed circuit state.
