摘　　要：软件FMEA(失效模式和影响分析)是硬件或系统FMEA的扩展,并应用于安全关键软件的鉴定,但是,目前缺乏应用经验。本文阐述了SFMEA的原理、实施过程和要点,提出了适用于某嵌入式软件的失效模式及原因,对失效模式的影响进行了严酷度等级分类,给出了对该软件实施SFMEA的过程和结果。结果表明了SFMEA的有效性和实用性。Software failure modes and effect analysis（SFMEA） is the extension of hardware or system FMEA,which is used to test and verify safety-critical software.However,there is lack of experiences in practice at present.In this paper,the principle,process and key points of software FMEA implementation are described.Then the failure modes and their causes of an embedded software are proposed as well and the effects of the failure modes are classified according to their severity.Finally,the process and results of SFMEA on this software are given.The results show the validity and practicality of SFMEA.

关 键 词：软件失效模式和影响分析 软件可靠性 软件可靠性分析
