A new enhanced constructive decomposition and mapping algorithm

Abstract

Structuring and mapping of a Boolean function is an important problem in the design of complex integrated circuits. Library-aware constructive decomposition offers a solution to this problem. This paper proposes novel techniques to improve the quality and runtime of constructive decomposition. The improvements are effective both in the stand-alone mapping procedure and in the context of re-synthesis applied to a mapped multi-level network. Experiments with public and proprietary benchmarks show promising results.
