ABSTRACT:
A method of obtaining a resolution-based proof of unsatisfiability using a SAT procedure for a hybrid Boolean constraint problem comprising representing constraints as a combination of clauses and interconnected gates. The proof is obtained as a combination of clauses, circuit gates and gate connectivity constraints sufficient for unsatisfiability.
