Abstract: The elimination-evolution self-repair method can be used to increase the self-repairing capacity of target circuit by optimizing circuit structure. There has been little research on the target circuit evaluation in optimization process. Based on the mathematical description of embryonics array state and target circuit form, an evaluation method is proposed with Markov unrepairable system theory. The calculating method for state division, transition rate of state, and probability of working states is researched, and the reliability and mean time-to-failure of target circuit are calculated to evaluate the target circuit. The simulated and experimental results show that the proposed method can effectively evaluate the circuit forms in evolution process.

Key words: system assessment and feasibility analysis, embryonics array, elimination-evolution self-repair, reliability evaluation, Markov unrepairable system
