Abstract :
It is observed that in some circuits, highly active output-patterns fall into a small set. Based on this observation, we propose an output directed decomposition architecture and an algorithm to synthesize the decomposed logic. The results on several MCNC benchmark circuits shows that the proposed method can achieve 34.1% reduction is power as compared to circuits without decomposition.
