Abstract: Circuit knowledge representation is the primary problem in the analog circuit evolution. The netlist coding is brief and has no limit on the topology, however, it generates a large number of illegal circuits during population initialization and genetic operations. This paper presents a structural matrix approach to solve the problem. The approach first summarizes the nature of the legal structure matrix, then uses the properties design population initialization steps and appropriate crossover operator. Proof of concept is given by two sets of evolutionary experiments. The results show that the proposed method can solve the problem of netlist coding.
