Several new concepts to bridge the "Logic Effort" research and SoC timing closure practice

Abstract

"Logic Effort" is academic research in the field of circuit optimization. The aim of this research is to achieve the fastest circuit implementation of a logic function by using the least amount of silicon resource. The fruit of this "Logic Effort" research has been utilized by Magma in real world timing closure practice and has resulted in significant success. However, the "gain" concept used by Magma in its practice is not user-friendly and has caused lot of confusions. This paper introduces several new concepts which can function as a bridge between the "Logic Effort" circuit optimization technique and real world timing closure practice.
