Cartesian GP in Optimization of Combinational Circuits with Hundreds of Inputs and Thousands of Gates
Genetic programming, Cartesian Genetic Programming, Evolutionary optimization, Combinational circuits, Formal verification
A new approach to the evolutionary optimization of large digital circuits is introduced in this paper. In contrast with evolutionary circuit design, the goal of the evolutionary circuit optimization is to minimize the number of gates (or other non-functional parameters) of already functional circuit. The method combines a circuit simulation with a formal verification in order to detect the functional inequivalence of the parent and its offspring. An extensive set of 100 benchmarks circuits is used to evaluate the performance of the method as well as the utilized evolutionary approach. Moreover, the role of neutral mutations in the context of
evolutionary optimization is investigated. In average, the method enabled a 34% reduction in gate count even if the optimizer was executed only for 15 minutes.
