Abstract
A Field Programmable Gate Array (FPGA) core cell with one or more Look-Up Tables (LUTs) and a selectable logic gate is presented as a space-efficient alternative to the conventional LUT-based FPGA core cell. An algorithm based upon the familiar FlowMap algorithm for LUT-based FPGA core cells implements the mapping of a Boolean logic network into the disclosed FPGA core cell.
