摘要:

在嵌入式控制系统中,由于软件复杂性导致例如与时序相关的问题,软件缺陷的潜在风险一直在增加。这些缺陷很少通过测试或模拟发现。为了检测这种缺陷,我们提出了一种建模方法,可以生成软件模型的模型检验与程序切片技术的基础上的变量依赖图。最后将该方法应用于一个汽车控制软件的实例中,验证了该方法的有效性。此外,我们开发了一个软件工具来自动化模型生成,并取得了35%的总验证时间减少模型检验。

英文摘要:

In embedded control systems, the potential risks of software defects have been increasing because of software complexity which leads to, for example, timing related problems. These defects are rarely found by tests or simulations. To detect such defects, we propose a modeling method which can generate software models for model checking with a program slicing technique based on a variable dependence graph. We have applied the proposed method to one case in automotive control software and demonstrated the effectiveness of the method. Furthermore, we developed a software tool to automate model generation and achieved a 35% decrease in total verification time on model checking.
