碩士 === 國立交通大學 === 資訊科學與工程研究所 === 104 === Device aging, which causes significant loss on circuit performance and lifetime, has been a primary factor in reliability degradation of nanoscale designs. Aggressive technology scaling trends, such as thinner gate oxide without proportional downscaling of supply voltage, aggra-vate the aging impact and thus necessitate an aging-aware reliability verification and optimi-zation framework during early design stages. In this thesis, we propose to exploit timing spec-ulation for aging resilience, based on deploying Razor flip-flops. By formulating the problem based on Boolean satisfiability, for the first time we can determine a feasible deployment of Razor flip-flops, such that maximum degree of aging resilience can be achieved in a cost-effective manner. Experimental results show that more than 50% of aging-induced perfor-mance degradation can be recovered, while reducing the number of required Razor flip-flops by about 70%, as compared to the case of naïve Razor flip-flop deployment.
