M32: a constructive multilevel logic synthesis system
V.N. Kravets, K.A. Sakallah · 2002
We describe a new constructive multilevel logic synthesis system that integrates the traditionally separate technology-independent and technology-dependent stages of modern synthesis tools. Dubbed M32, this system is capable of generating circuits incrementally based on both functional as well as structural considerations. This is achieved by maintaining a dynamic structural representation of the evolving implementation and by refining it through progressive introduction of gates from a target technology library. Circuit construction proceeds from the primary inputs towards the primary outputs preliminary experimental results show that circuits generated using this approach are generally superior to those produced by multi-stage synthesis.
