Satisfiability (SAT) is a computationally expensive algorithm central to many CAD and test applications. In this paper, we present the architecture of a new SAT solver using reconfigurable logic. Our main contributions include new forms of massive fine-grain parallelism and structured design techniques based on iterative logic arrays that reduce compilation times from hours to a few minutes. Our architecture is easily scalable. Our results show several orders of magnitude speed-up compared with a state-of-the-art software implementation, and with a prior SAT solver using reconfigurable hardware
