Study of Chip Level Self-Repaired Technology Based on EHW

In extreme environment, the electronic system is being continuously bombarded by harmful radiation. This can cause local damage of the circuit and result in failure of the entire system. In this paper we introduced a new technology EHW (evolvable hardware technology) to repair the function of the system. EHW is a kind of hardware that can change its architecture and behavior dynamically and autonomously. The introduction of EHW technology can improve the system´s reliability and self-repaired capability in extreme environment.
