Actiniaria: Distributed Dynamic-IR-Drop-Aware Timing Monitor for AVFS With Lightweight Tentacles

Actiniaria: Distributed Dynamic-IR-Drop-Aware Timing Monitor for AVFS With Lightweight Tentacles 150 150

Abstract:

Advances in integrated circuit (IC) technology have amplified the effects of process, voltage, and temperature (PVT) variations, particularly dynamic IR drop, which severely affects timing. Post-silicon IR drop monitoring circuits are lacking, forcing designers to reserve substantial static guard bands for worst-case scenarios, compromising energy efficiency. Inspired by biomimetics, this …
