Improvements to Delay-driven LUT Mapping
DescriptionAshenhurst-Curtis decomposition (ACD) is a known decomposition technique used, in particular, to map combinational logic into LUT structures when synthesizing hardware designs. However, available implementations of ACD suffer from excessive complexity and slow run time, which limits their applicability and scalability. This paper presents several simplifications leading to a fast and versatile technique of ACD suitable for delay optimization. We utilize this new formulation to enhance delay-driven LUT mapping by performing ACD on the fly. Compared to state-of-the-art technology mapping, experiments demonstrate an average delay improvement of 17.94%, with affordable run time. Additionally, our method improves heavily optimized LUT networks.
