Abstract
A method for characterizing cell interconnect delay is disclosed that may be included in a library for use with logic design tools. A method of characterizing cell interconnect delay includes the steps of (a) receiving as inputs a plurality of input ramptimes and a plurality of interconnect lengths for a selected cell, and (b) calculating an output ramptime and a total cell delay including a cell delay and an interconnect delay for each of the plurality of input ramptimes for each of the plurality of interconnect lengths for the selected cell from the inputs.
