This characteristic enables polymorphic circuit can be widely applied to fault diagnosis of digital circuit
synthesis of multifunctional digital circuit
etc.Polymorphic gate plays a vital role in the design of polymorphic circuit.However
until so far
there is no effective method for the synthesis of polymorphic gate.This paper proposes a new method for the synthesis of polymorphic gate
which use graph to represent circuit.The method specially designs a serial of operator to modify the circuit structure or parameter.Experiment results show that the method can synthesis various of polymorphic gate effectively.
