Abstract: For large scale or very large scale embryonic circuits, in the process of function differentiation and self-repairing faced with the problems such as huge hardware consumption, huge time consumption and hard to completed and so on, in this paper, a Bus-based Embryonic Array（BEA） is proposed, which is based on the function decomposition. The structure of BEA is designed, a new self-repairing strategy is put forward, and the comparison of the BEA with the original array structure is analyzed. The resource consumption and the reliability of the BEA are analyzed with different cells composition. Considering the resource consumption and the reliability of the BEA, the choice of spare cells in BEA is researched, to ensure the less resource consumption with the same reliability. The research on the spare cells in the BEA is helpful to the design of the real circuit.
