Die-to-die and within-die variations impact the frequency and power of fabricated dies, affecting functionality, performance, and revenue. Variation-tolerant circuits and post-silicon tuning techniques are important for minimizing the impacts of these variations. This paper describes several circuit techniques that can be employed to ensure efficient circuit operation in the presence of ever-increasing variations. Categories and Subject Descriptors B.7.1 [Integrated Circuits]: Hardware – Types and design styles. General Terms: Design, Reliability, Performance
