Software FMEA for Safety-Critical System Based on Co-analysis of System Model and Software Model

Abstract

SUMMARYSoftware FMEA is valuable and practically used for embedded software of safety-critical systems. In this paper, a novel method for Software FMEA is presented based on co-analysis of system model and software model. The method is hopeful to detect quantitative and dynamic effects by a targeted software failure. A typical application of the method is provided to illustrate the procedure and the applicable scenarios. In addition, a pattern is refined from the application for further reuse.

A Novel Qt-Based FMECA Platform: Methodology and Architecture

“…Software FMEA is valuable and practical for embedded software engineering. For example, at early stage of embedded software lifecycle, it is used for determine the critical level of the software and at verification stage, it is valuable for efficient and effective testing [3].…”
