Performance directed synthesis for table look up programmable gate arrays

Abstract

The authors address the problem of delay optimization for programmable gate arrays. The main considerations are the number of levels in the circuit and the wiring delay. The authors propose a two-phase approach: the first phase involves delay optimizations during logic synthesis before placement, while the second uses logic resynthesis in the case of a timing-driven placement technique. Results and comparisons on benchmarks are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
