摘要
以需求描述模型 RTRSM为基础 ,通过建立抽象的、能将控制流和数据流等有机地结合到一起的实时软件的动态执行模型 ,提出了构图覆盖的动态检测方法 ,并给出了其具体算法 .该方法能检测嵌入式实时软件系统动态执行步中各并行成分及其相互间的执行情况 ,而且也可为分析员提供一些有用的检测信息以提高分析和检测软件需求的效率 .
On the basis of requirements description model RTRSM, this paper presents an abstract dynamic execution model(DEM)of real time software systems which can integrate with control flow and data flow, and then describes a checking method based on configuration covering and proposes its corresponding algorithm. This checking method can check the execution situations between parallel elements in a dynamic execution step of embedded real time software systems. In addition, this method also provides some information for analysts that is helpful to improve the efficiency of analyzing and checking software requirements.
