| Abstract: | Bionic self‐repair circuit is an advanced technique which has the abilities of on‐line fault detection and self‐repairs ,and has broad application prospects in aerospace fields which need high reliability .A novel basic logic cell for bionic self‐repairing circuits is designed in this paper .This cell can be flexibly configured according to the customer’s requirements and has the ability of on‐line testing .Simulations and hardware experiments show that the cell can implement the functions proposed by the user and the inserted faults can be detected concurrently . The hardware overhead is less than the traditional concurrent test circuits and time redundancy is acceptable .Therefore ,the design meets the requirements of bionic self‐repair circuit . |
