Self-repairing digital systems have recently emerged as the most promising alternative for fault-tolerant systems. The proposed system is developed for automatically detect the fault and correcting it in digital system with high efficiency using self-repairing technique. It composed of structural layer and gene control layer. The structural layer consists of working modules, spare modules and their interconnections. In these system, each module of our system connecting with four spare modules for replacing faulty working modules at four times. Gene control layer controls the operation of modules. The module is the encoded data, called the genome, contains information about the function and the connection. Therefore, a faulty module can be replaced and the whole system’s functions and connections are maintained by simply assigning the same encoded data to a spare (stem) module. The gene control layer determines the neighboring spare module in the structural layer to replace the faulty module without collision. We verified the self repairing digital system mechanism by simulating the system in Xilinx software.
