Patent ID: 8234608

Claim:
A circuit specification description visualizing device, comprising: a circuit specification description analyzing section configured to analyze a syntax of a circuit specification description to create structure data about a partial expression included in the circuit specification description; a pass pattern creating section configured to create data about a plurality of pass patterns for which the circuit specification description passes from the structure data created by the circuit specification description analyzing section; a waveform data creating section configured to create waveform data about a waveform of at least one signal in a circuit defined by the circuit specification description based on data about each of the plurality of pass patterns created by the pass pattern creating section; a correlation data creating section configured to create correlation data that indicates a correlation between the waveform of the at least one signal and the partial expression included in the circuit specification description based on the data about each of the plurality of pass patterns; and a display data outputting section configured to output display data so as to show the correlation between the partial expression included in the circuit specification description and the waveform of the at least one signal for each of the plurality of pass patterns based on the structure data, the waveform data and the correlation data, the display data being outputted for displaying a waveform display section including a waveform diagram showing the waveform of the at least one signal, a structure display section showing the partial expression, an a correlation display section showing the correlation between each part of the waveform displayed in the waveform diagram and the partial expression displayed in the structure display section based on the correlation data, on a display device having a display screen.
