PROBLEM TO BE SOLVED: To reduce the man-hour for signal selection by selecting an arbitrary signal and displaying a waveform by extracting information related to that signal from signal information making the connection condition and signal change condition of each signal correspondent to the related signal. SOLUTION: In a logic simulation, a signal connection information extraction processing part 130 extracts the signal connection information from a logic description file 100 storing the signal connection information of an electronic circuit. A signal change information extraction processing part 140 extracts the signal change information in the logic simulation. A waveform processing part 170 generates signal information making the connection condition and signal change condition of each signal correspondent to the related signal based on the signal connection information and the signal change information extracted by the signal connection information extraction processing part 130 and the signal change information extraction processing part 140. Based on an extracted signal connection information file 160, an arbitrary signal is selected, information concerning that signal is extracted from signal information, and the waveform is displayed on a waveform display input/output device 190. |
