摘要
嵌入式系统软件可靠性设计不足引发的问题数量呈上升趋势,如何在软件产品交付前评估软件可靠度已成为亟待解决的问题.当前的软件可靠度评估理论源于硬件可靠性体系,已形成了适用于不同的场合较多的评估方法,但存在使用时难以获得可靠性数据的问题,可操作性不强。代码是软件的关键属性,采用软件代码分析的方法,提出一种基于代码路径的软件可靠度评估方法,利用已有的项目软件测试数据验证该评估模型,进而给出提高软件可靠度的设计方法,可有效指导嵌入式软件可靠度评估并提高软件可靠性设计质量.
The number of problems caused by insufficient reliability design of embedded system software is on the rise.How to evaluate software reliability before software delivery has become an urgent problem to be solved.The current software reliability assessment theory originates from the hardware reliability system,and has formed assessment methods suitable for different occasions.However,it is difficult to obtain reliability data during use and the operability is not strong.Code is the essential attributes of software,using the method of software code analysis,proposes a software reliability assessment method based on the code path,using the existing project software test data validate the assessment model,and gives the design method to improve the reliability of software»which can effectively guide the embedded software reliability evaluation and improve the quality of software reliability design.
