Simulation method of electromagnetic field and circuit analysis on first and second targets coupled together by a circuit element simulation apparatus, and computer-readable medium storing simulation program for performing the method

摘要

A simulation apparatus according to an embodiment performs an electromagnetic field circuit coupling analysis on a first substrate and a second substrate electrically coupled via a circuit element having a finite delay time. A first coupling analysis unit carries out a time domain electromagnetic field analysis and also a circuit analysis on a circuit element at a first analytical domain including the first substrate. The second coupling analysis unit carries out a time domain electromagnetic field analysis and also a circuit analysis on a circuit element at a second analytical domain including the second substrate. A cable internal state analysis unit carries out a circuit analysis on a circuit element, employing an electromagnetic field value obtained at the first coupling analysis unit at one terminal of the circuit element connecting the first substrate and the circuit element, and an electromagnetic field value obtained at the second coupling analysis unit at another terminal of the circuit element connecting the second substrate and the circuit element.
