The controllable silicon evolution was realized inside FPGA by imitating evolution process of the carbon-based biologies in the natural world. According to the common SA faults in electronic systems,an intrinsic evolvable fault-tolerant mod-el based on evolution of hardware technology is proposed. Through loading Microblaze CPU inside FPGA and establishing recon-figurable arrays,the evolution-in-chip of evolvable hardware was implemented. Fault tolerance experiment was done to test the capability of fault-tolerance by the model. The experimental result shows that method can effectively improve the reliability of dig-ital circuits.
