Xtmap: generate-and-test mapper for table-lookup gate arrays

Introduces Xtmap, a technology mapper for f-input table-lookup cells based on a generate-and-test paradigm. Xtmap can optimize for area and delay simultaneously and produces smaller circuits than previous mappers that considered delay, while matching their delay values. Tables of benchmark results are used to compare Xtmap with Xmap, Dagmap, FlowMap, chortle-d, and mis-pga covering algorithms.<>
