Abstract
In a gate-level logic simulation, a change in electric current is calculated from event information 5 output from a logic simulator 4 through use of a current waveform calculation section 7. The thus-calculated change in current is subjected to FFT processing through use of an FFT processing section 9, thereby determining a frequency characteristic of EMI and enabling EMI analysis.
