A method and system of converting an ASCII timing report to a timing waveform to evaluate the behavior of an electrical signal in an ASIC is described. In the method, a timing report is read into memory, and selected timing points are extracted therefrom. A timing waveform is generated from the extracted timing points for display and review by a designer to evaluate whether a given external port or internal pin of the ASIC meets required timing specifications. To create a combined timing waveform, max and min timing waveforms are generated from selected timing points extracted from max and min timing reports. The x-y coordinates of the min timing waveform are shifted by an adjustment factor so as to align with x-y coordinates the max timing waveform, then a combined timing waveform is generated from the x-y coordinates of both the max and min timing waveforms. |
