摘要

New insights on the stochastic nature of aging-related timing impact in digital circuits trigger the need for aging compensation control loop. Such control loops enable additional 22% power savings but require dedicated safety measures (either margin or monitoring) to enable fault-free operations even in cases of out-of-specifications usage.
