Abstract-A fast and accurate statistical method that estimates at gate level the leakage power consumption of CMOS digital circuits is demonstrated. Means, variances and correlations of logic gate leakages are extracted at library characterization step, and used for subsequent circuit statistical computation. In this paper, the methodology is applied to an eleven thousand cells ST test IP. The circuit leakage analysis computation time is 400 times faster than a single fast-Spice corner analysis, while providing coherent results.
