In this article, we propose a generic design methodology to achieve area-efficient reconfigurable logic circuits by using exact synthesis based on Boolean satisfiability (SAT) solver. The proposed methodology better leverages the high representation ability of emerging reconfigurable logic gates (RLGs) to achieve reconfigurable circuits with fewer gates. In addition, we propose a fence-based acceleration method to provide >10× speed up for the synthesis without an observable loss of optimality. Furthermore, four sets of RLGs are developed based on a recently proposed valley-spin device as a case study to demonstrate the advantage of the proposed circuit. Simulations have been performed to analyze the impact of the fence searching algorithm and combination of operators. Based on disjoint-support decomposable (DSD) benchmarks, up to 38% and 73% reductions are observed in the area and energy-delay-area product (EDAP), respectively, compared to CMOS counterparts. Compared to the two existing synthesis methods, the proposed scheme provides 40% and 26.3% reduction in EDAP based on MCNC benchmark.
