Abstract: Because of the existence of a great deal of imbedded software,the fault model of software-intensive system is changed,and a new correlative fault between software and hardware appears.This paper analyses the characteristics of the correlative fault between software and hardware firstly,and then a DFTA based fault diagnosis method is proposed.The analyzing process is also present in the paper.In the end,the feasibility of this method is proved by an example.

Key words: correlative fault between software and hardware, Dynamic Fault Tree Analysis(DFTA), fault diagnosis

摘要: 软件密集型系统中由于有大量软件的嵌入,其故障模式发生了变化,产生了新的软硬件相关的故障模式。在分析软硬件相关故障特征的基础上,提出了一种基于动态故障树分析方法的故障诊断方案,并给出了分析方法和步骤。最后通过实例分析,证明了这种方法的可行性。
