摘　　要：软件失效模式和影响分析(SFMEA)是提高软件可靠性的一种重要方法。针对人工SFMEA分析费时费力的问题,着眼于SFMEA的分析过程,对系统级SFMEA计算机辅助设计及相应辅助工具的实现展开了研究,介绍了系统级SFMEA分析的具体步骤,提出了对软件功能单元建模辅助生成软件约定层次,由已有通用失效模式库和相邻层次分析结果辅助获取软件失效模式、软件失效原因和纠正措施辅助设计等,并在此基础上开发了相应的辅助工具,从而减少SFMEA的分析工作量,提高SFMEA分析的效率。Software failure modes and effects analysis（SFMEA for short） is a important method to improve software reliability. To solve the time-consuming problem of the artificial SFMEA, with a view to the SFMEA＇ s process, the research on system SFMEA computer aided design and corresponding tool were carried out, the specific steps of the system SFMEA were introduced, the aided design methods as follows were advanced： the software conventional level was made by modeling the functional unit; the software failure mode was acquired from the existent failure mode and the analysis results of the adjacent level; the software failure cause and corrective measures were designed, and the corresponding tool was developed to reduce the system SFMEA＇s workload and improve the system SFMEA＇s efficiency.
