Title
A Signal Correlation Guided Circuit-SAT Solver
Abstract
We propose two heuristics, implicit learning and explicit learning, that utilize circuit topological information and signal correlations to derive conflict clauses that could efficiently prune the search space for solving circuit-based SAT problem instances. We implemented a circuit-SAT solver SC-C-SAT based on the proposed heuristics and the concepts used in other state-of-the-art SAT solvers. For solving unsatisfiable circuit examples and for solving difficult circuit-based problems at Intel, our solver is able to achieve speedup of one order of magnitude over other state-of-the-art SAT solvers that do not use the heuristics.
