Technology mapping is an important step in the FPGA CAD flow in which a network of simple gates is converted into a network of logic blocks. This article considers enhancements to a traditional LUT-based mapping algorithm for an FPGA comprised of logic blocks which implement only a subset of functions of up to k variables; specifically, the logic block is a partial LUT, but it possesses more inputs than a typical LUT. An analysis of the logic block is presented, and techniques for postmapping area recovery and timing-driven buffer insertion are also described. Numerical results are put forth which substantiate the efficacy of the proposed methods using real circuits mapped to a commercial FPGA architecture.
