摘要：
A device for simulating circuits is provided with an identifying system and a verifying system. The identifying system identifies a pair of wires in which two signals operate simultaneously within an appointed period and a pair of wires in which two signals do not operate almost simultaneously within the appointed period. The verifying system verifies actions of a circuit to be analyzed, under an assumption that the coupling capacitor between the pair of wires in which it is judged by the identifying system that two signals do not simultaneously operate within the appointed period is a ground capacitor.
