Abstract: To overcome the shortcomings of embryonic circuit and its self-repair methods-row/column elimination and cell elimination, a novel embryonic self-repair system with evolutionary capacity was presented. There are three layers, including functional layer, repair layer and evolutional layer, in the proposed self-repair system. The target circuit's function can be implemented in the functional layer, and the target circuit not only can be rapidly repaired in real time by the repair layer through row/column elimination, but also can be evolved by the evolutional layer based on the remaining cell resource of the functional layer. The self-repair system not only ensures real-time self-repair of the target circuit, but also takes full advantage of electronic cell resource in the functional layer, which improves the self-repair capacity of the target circuit. At last, the superiority of the proposed self-repair system was verified through a circuit simulation experiment.
