Self-Heating Effects (SHE) is known as one of the key reliability challenges in FinFET and beyond. Large timing guard bands are necessary, which we try to reduce. In this work, we propose operating (biasing) processors at Zero-Temperature Coefficient (ZTC) to contain (mitigate) SHE-induced delay. Operating at ZTC allows near-zero timing guard band to protect circuits against SHE. However, a trade-off is found between thermal timing guard band and performance loss from lowering the voltage.
