EFFICIENT CELL SWAPPING SYSTEM FOR LEAKAGE POWER REDUCTION IN A MULTI-THRESHOLD VOLTAGE PROCESS

摘要

A method for designing an integrated circuit, comprising the steps of (A) calculating an efficiency value for each of a plurality of equivalent cells in the design; and (B) selecting a number of the plurality of equivalent cells based on the efficiency values. The equivalent cells (i) decrease an overall delay of a path to meet a timing specification, and (ii) minimize an increase in overall leakage current.
