Development of Data Flow Testing Tool For Railway System Embedded Software

초록

In accordance with the development of recent computer technology, the dependency of railway signaling system on the computer software is being increased further, and accordingly, the testing for the safety and reliability of railway signaling system software became more important. In this paper, we suggested an automated tool for data flow testing in railway system, and presented its result of implementation. The analysis items in the implemented tool had referred to the international standards in relation to the software for railway system, such as IEC 61508 and IEC 62279. In these international standards, 'data flow testing' for railway system embedded S/W has to be recommended highly. The proposed tool can be utilized at the assessment stage and also the software development stage.
