Automatic Waveform Generation Technique for Special Sequential Circuit in Logic Parameter Extraction

An automatic waveform generation technique has beenproposed，which is used for the SPICE simulation when extracting the logic parameters for a special sequential logic circuit.It is also used to generate SPICE stimulus waveforms for these special sequential logic circuits quickly according to user’s logic parameter specifications, as can speed up the logic parameter extraction process and guarantee a proper SPICE simulation waveform for the logic extraction. With it the extraction of logic parameters becomes completely automatic and the time to establish the logic parameter library is greatly reduced.
