Activity Based System Reliability Evaluation Flow

Projektbeschreibung

Innovative Einschätzung der Zuverlässigkeit von elektronischen Systemen

Hochgradig präzise Zuverlässigkeit von elektronischen Systemen ist wichtig für deren effiziente Leistung. Das EU-finanzierte Projekt ABSREF will diese einschätzen. Das Projekt wird einen innovativen lastabhängigen und für Alterung sensiblen Simulationsrahmen mit akzeptabler Laufzeit einführen. Dieser allgemeine Rahmen wird die Durchführung von Systemoptimierungen hinsichtlich mehrerer mit Alterung zusammenhängender Phänomene, darunter Temperaturschwankungen bei negativer und positiver Vorspannung, ermöglichen. Der durch diese Strömung verbesserte Zeitrahmen und Schutzbereich wird vermutlich dazu beitragen, die Geschwindigkeit, Leistung und Haltbarkeit von elektronischen Systemen zu verbessern und Kosten zu senken.

Ziel

This proposal envisions to foretell the reliability of electronic systems with high degree of accuracy by introducing a novel workload dependent aging aware simulation framework which has acceptable run-time. The framework is generic in nature and will enable one to perform system optimization in presence of multiple aging related phenomena including negative bias temperature instability, positive bias temperature instability, and hot carrier injection. Thus the benefits of the improved timing margin or guard-band incurred by this flow can be leveraged to further improve speed, power, durability of electronic systems and reduce cost. An efficient workload abstraction scheme will be employed which speeds up the transistor level degradation evaluation with accuracy comparable to that of cycle-accurate simulations. Using the device level degradation results, standard cell library characterization will be performed by statistical methods based on Design of Experiments and Response surface Modelling approach. The created workload dependent, aging aware cell libraries will be used to carry out static timing analysis and optimization. Critical path delay degradation evaluated under this framework will be compared with the corner based aging analysis to highlight the impact of the innovation. The framework will be validated using industry standardized, CPU intensive SPEC2006 benchmark suite run on top of multi-core industrial processor. Considering its interdisciplinary nature, the project will help bridge the gap between two disciplines: the device level reliability research and system level interactions. Working in highly international and intersectoral environment of the host IMEC, Dr. Mishra will enhance his professional skills to become a mature independent researcher.
