A compact error model for reliable system design

Permanent and transient errors are inherently different in property and effect. This paper shows how to utilize this fact to develop a System Error Decision Diagram for reliable embedded systems. Based on this model an efficient approach for reliability evaluation is developed. The model and the reliability evaluation approach are assumed to be employed in a system-level design process to accelerate design space exploration. The proposed approach is demonstrated for a control system taken from the automotive domain.
