本文的目的是引入一种新的表示法，作为一种同时考虑永久性误差和时间误差的方法，以提高嵌入式系统的整体可靠性。嵌入式系统在安全关键应用中的部署，例如在汽车领域，需要扩展由功能、及时性和生产成本组成的基本设计标准集，以将可靠性作为优化标准来考虑。因此，可靠性工程成为嵌入式系统总体设计流程的一部分。所提出的方法是基于引入永久/瞬时错误判定图和用于生成系统实现集的专用算法，该系统实现集具有在冗余资源方面以最小成本获得最大可靠性的特点。以汽车领域的控制系统为例，说明了所提出的方法。
The objective of this paper is to introduce a novel representation as a means to consider both permanent and temporal errors in order to increase the overall reliability of an embedded system. The deployment of embedded systems in safety critical applications, e.g. in the automotive domain, demands that the fundamental set of design criteria consisting of functionality, timeliness, and production costs be extended to consider of reliability as an optimization criterion. Thus reliability engineering becomes part of the overall design flow for embedded systems. The proposed approach is based on the introduction of permanent/transient error decision diagrams and on dedicated algorithms for the generation of system implementation sets which feature maximum reliability at minimal costs in terms of redundant resources. The proposed approach is demonstrated for a control system taken from the automotive domain.
