Abstract
An equivalent input characterization waveform (EICW) is determined for a channel-connected block (CCB) located on a boundary of a cell, for a specific waveform of interest. The EICW and the specific waveform of interest produce a same timing characteristic of the CCB, but the EICW belongs to a set of waveforms on which a behavioral timing model for the multi-stage cell is based whereas the specific waveform of interest is not so limited. A timing response of the multi-stage cell is then estimated based on applying the EICW.
