We introduce a new method for two-level logic minimization. Unlike previous approaches, the new method uses a SAT solver as an underlying engine. While the overall minimization strategy of the new method is based on the operators as defined in ESPRESSO-II, our SAT-based implementation is significantly different. The new minimizer SAT-ESPRESSO was found to perform 5-20 times faster than ESPRESSO-II and 3-5 times faster than BOOM on a set of large examples.
