A Sequential Procedure for Average Power Analysis of Sequential Circuits

A new statistical technique for average power estima-tion in sequential circuits is presented. Due to the feed-back mechanism, conventional statistical procedures cannot be applied to infer the average power of sequential circuits. As a remedy, we propose a sequential procedure to deter-mine an independence interval which is used to generate an independent and identically distributed (iid) power sam-ple. A distribution-independent stopping criterion is applied to choose an appropriate convergent sample size. The pro-posed technique is applied to a set of sequential benchmark circuits and demonstrates high accuracy and efficiency. I
