Razor II: In Situ Error Detection and Correction for PVT and SER Tolerance

Research paper

Performance variation due to PVT uncertainty has led to an increased interest in adaptive designs. Traditional methods for adaptive design have used so-called canary circuits that mimic the critical-path delay of the actual design [1-4]. However, canary circuits require safety margins for possible mis-tracking and intradie PVT variations. They also have difficulty responding to rapidly changing conditions.
