摘要
常规的基于EHW的故障自修复策略存在故障修复类型单一、面对大规模电路修复速度慢、不能实时快速自适应的修复故障等问题。为克服以上问题,在前期工作中提出的基于EHW和RBT的故障自修复策略基础上,对不同故障类型下的故障快速修复策略进行了研究。由于不可能预知实时检测到的故障类型,在提出的快速修复策略中,统一将检测到的故障作为固定型故障进行修复;演化算法根据故障信息演化矫正电路,MUX根据实时检测到的故障信息进行开断,保证UUT正常运行。通过实例仿真证明,提出的快速修复策略的可行性和有效性得到了验证。
As a result of the conventional fault self-repair strategy based on evolvable hardware （EHW） had a lot of problems, for example, single fault repair types, slowly repair speed for very large scale integration（VLSI） , without repair fault self-adaptive in time, and so on. In order to overcome above problems, on this basis of previous work which proposed the fault self-repair strategy based on EHW and reparation balance technology （ RBT）, this paper researched a rapid fault self-repair strategy under the different fault types based on EHW and RBT. Because real-time detected faults＇ types couldn＇ t be judged, all detected faults would be as stuck-at faults. Then rectification circuit （RTC） was evolved by evolutionary algorithm （EA）, MUX implemented on-off control based on detected faults information. These steps can guarantee normally work of UUT. The instance sim- ulations prove the feasibility and validity of proposed rapid fault self-repair strategy.
