CRAU

Kompositionelle Zuverlässigkeitsanalyse auf Systemebene unter Berücksichtigung von Unsicherheiten

CRAU Compositional System Level Reliability Analysis in the Presence of Uncertainties Ever shrinking device structures are one of the main reasons for a growing inherent unreliability of embedded system components. The small device structures are susceptible to, e.g., environmental changes like cosmic rays or to manufacturing tolerances. These so-called uncertainties are due to changes and can only be approximated or estimated at design time. The ultimate goal of this project is the investigation and development of a methodology for system-level reliability analysis and design of reliable systems through means of self-adaptation and error-resiliency. This project focuses on (a) the development of suitable cross-level reliability analysis techniques that combine various reliability analysis techniques across different levels of abstraction, (b) enrich well-known reliability analysis techniques by the ability to consider and explicitly model uncertainties, and (c) integrate such a compositional analysis into a system-level design space exploration to allow for cost evaluation of reliability-increasing techniques.
