Polymorphic gates are unconventional logic components which can switch their logic functions according to changing environment. The first part of this study presents an evolutionary approach to the design of polymorphic modules which exhibit different logic functions in different environments. The most complicated circuit that we evolved contains more than 100 gates. The second part of this study shows how to reduce the number of test vectors of a digital circuit by replacing some of its gates… CONTINUE READING
