With the continuous improvement of the complexity of the microelectronic system, its reliability risk is becoming more and more obvious. In order to improve the reliability of electronic systems in complex electromagnetic environment, this paper proposes a new fault self-repairing method; the idea is to realize controllable silicon evolution on the FPGA. A MicroBlaze CPU and VRC array are designed, and the CPU runs the evolutionary algorithm to configure the VRC array, dynamically changing the structure and function of the circuit, so as to obtain high reliability of the digital fault self-repairing circuit. Evolving fault self-repairing technology provides a new way for the high reliability of the digital system design.
