Abstract

This paper details a novel power estimation algorithmbased on Rate of Bit Propagation (RBP).Considering thereduction of RBP an advanced Scan Array architecture isproposed in which a wrapper and two dimensions scanchain is adopted.Estimated results based on RBP andexperiment results of industrial circuits both show thattesting power was reduced to the level of the functionalpower.Furthermore Pseudo-BIST is integrated with thewrapper to reduce the test time.
