Kompositionelle Zuverlässigkeitsanalyse auf Systemebene unter Berücksichtigung von Unsicherheiten
Zusammenfassung der Projektergebnisse
Continuous technology scaling results in higher vulnerability of today’s electronic devices to e. g., neutron-induced soft errors, negative bias temperature instability, short-channel effect, gate leakage, etc. These devices may be embedded in safety-critical systems, such as autonomous cars, where reliability plays an important role. Thus, it is vital to evaluate the reliability of such systems at design time to seek for an appropriate reliability improving technique if necessary. In this project, we first proposed a methodology for cross-level reliability analysis to tame the ever increasing analysis complexity of embedded systems. This methodology combines various reliability analysis techniques across different levels of abstraction. Later in this project, we developed and incorporated efficient reliability analysis technique using stochastic logic. Moreover, we proposed to analyze system reliability more accurately through the consideration of common-cause failures among components as well as imperfect fault coverage. On the other hand, due to manufacturing tolerances and environmental changes, the reliability of system’s components cannot be precisely measured at design time and is considered uncertain. In this regard, we proposed to explicitly model uncertainty in the reliability of each component and derive the uncertainty at system level. The developed methodology is integrated into an automatic Electronic System Level (ESL) tool to allow for cost evaluation of reliability-increasing techniques and for Design Space Exploration (DSE). This tool uses meta-heuristic optimization algorithms and enables the comparison of system implementation candidates with objectives represented by uncertainty distributions. Moreover, various novel Importance Measure (IM) analysis techniques have been proposed in this project to provide an insight into the contribution of each component regarding the reliability of the system. To cope with huge design spaces, these techniques have been employed to steer the optimization algorithms in order to enhance the efficiency of the DSE.
