The objective of the paper is to introduce a new approach to the evolutionary design of polymorphic digital circuits conducted directly at transistor level. A discrete eventdriven simulator was utilized to achieve reasonable trade-off between performance and precision. The proposed approach was evaluated on a set of polymorphic logic circuits controlled by switching the power rails. It was demonstrated that the proposed method is able to produce valid solutions. A lot of polymorphic gates based on ambipolar transistors were designed, which provide transistor savings compared to existing circuits. A new class of polymorphic gates was discovered thanks to the proposed system - gates based on conventional MOS transistors whose functions are changed by switching the power rails. They seem to have the best parameters among currently known polymorphic gates based on conventional transistors.
