摘要
An approach for performing multiple voltage threshold timing analysis for a digital integrated circuit is described. In one embodiment, there is a multiple voltage threshold timing analysis tool for performing a multiple voltage threshold timing analysis of a digital integrated circuit having at least one logic gate loaded by an interconnect circuit. In this embodiment, a characterization data retrieving component is configured to obtain characterization data describing driving behavior of the at least one logic gate. An interconnect circuit model retrieving component is configured to obtain a model of the interconnect circuit. A multiple voltage threshold timing analysis component is configured to derive a sequence of crossing times for the driving point voltage waveform to advance between successive voltage thresholds. The multiple voltage threshold timing analysis component also generates a voltage waveform from the derived sequence of crossing times.
