Evolutionary topology programming for analog circuit fault tolerant design

In this paper, an evolutionary programming strategy based on netlist-based encoding is proposed. During the evolutionary process, mutation operators directly operate the connecting points. Besides that, we introduce the knowledge of graph theory into measuring the richness of circuit topological structure. Experimental results show that the proposed method is beneficial to generate circuits with various topologies. The experimental results of fault-tolerant tests based on structural failure model show that the richness of circuit topological structure is helpful to improving the fault-tolerant capability of analog circuits.
