System safety is considered as one of the most important non-functional requirements for safety-critical embedded systems. Several safety assessment methods have been proposed to evaluate safety-critical systems. However, most of them cannot be used to assess safety-critical design patterns due to the fact that these patterns do not address real systems but present abstract solutions to commonly recurring...
Design Patterns, which give abstract solutions to commonly recurring design problems, have been widely used in the software and hardware domain. This paper focuses on nonfunctional implications and side effects of the design patterns on safety critical applications, which are especially critical in embedded systems. We propose a pattern representation for safety critical embedded application design...
Software reliability represents a major requirement for safety critical applications. Several fault tolerance methods have been proposed to improve software reliability. These methods are based on either fault masking such as N-version programming or on fault detection such as in the recovery block method. The success of the recovery block method depends on a high quality of the effective acceptance...
