Reliability-Aware System Synthesis

Increasing reliability is one of the most important design goals for current and future embedded systems. In this paper, we will put focus on the design phase in which reliability constitutes one of several competing design objectives. Existing approaches considered the simultaneous optimization of reliability with other objectives to be too extensive. Hence, they firstly design a system, secondly analyze the system for reliability and finally exchange critical parts or introduce redundancy in order to satisfy given reliability constraints or optimize reliability. Unfortunately, this may lead to suboptimal designs concerning other design objectives. Here, we will present a) a novel approach that considers reliability with all other design objectives simultaneously, b) an evaluation technique that is able to perform a quantitative analysis in reasonable time even for real-world applications, and c) experimental results showing the effectiveness of our approach.
