Abstract: Most self-repair strategies of embryonic electronic arrays (EEA) only consider how to tolerate the faults from embryonic electronic cells. However, there is little concern about how to tolerate the faults from interconnect wires. The interconnect wires among cells are the data transmission channels. If there is any fault in the interconnect wires，the embryonic electronic array cannot work. A new self-repair strategy， the hybrid elimination strategy，is proposed. The hybrid elimination strategy can tolerate not only the fault of interconnect wires but also the fault of embryonic electronic cell. The effect of interconnect wires failure on the reliability of embryonic electronic array is analyzed. The structure of embryonic electronic array is designed based on the hybrid elimination strategy. The effectiveness of hybrid elimination strategy was verified by simulating and analyzing a 4-bit multiplier with a 7×6 embryonic electronic array. The simulated result shows that the hybrid elimination strategy can effectively tolerate the faults from cells and interconnect wires. The analyzed results of hardware resource consumption and reliability show that，for the hybrid elimination strategy，the hardware resource consumed by the part which is used to tolerate the fault of interconnect wires is very little，and the hardware resource consumption of the hybrid elimination strategy is acceptable；the hybrid elimination strategy has a better reliability performance than those of column elimination strategy and cell elimination strategy about imperfect interconnect wires，especially for the reliability of embryonic electronic array with large amount of interconnect wires.
