  • The application of extraction principle for logic function minimization to multiple-output cases is studied. The defect in original algorithm in dealing with multi-output extremals is complemented, and three kinds of less-than terms in different conditions are defined. In addition, three kinds of generations for the definition of less-than terms are given, so as to more efficiently find out the coverage with minimal number of terms and irredundant function outputs. Finally, an algorithm MOSE based on the work is presented.
