Abstract
Disclosed is a configurable hardware system and method for implementing instance-specific (per-formula) SAT-solver circuits. A template design is provided for producing these circuits on a per-formula basis. The typical hardware requirements for implementing the invention makes the design amenable to current or next-generation FPGA implementation. Hardware simulations indicate that for many difficult SAT problems, the system according to the invention can offer one to three orders of magnitude speedup over prior art software implementations.
