열차제어시스템 바이탈 소프트웨어 안전성 평가를 위한 테스트 도구의 검토

The portion of embedded software in railway signaling system is increased by the advance of computer and communication technology. And the safety requirements for railway system are standardized by int'l std., such as IEC 62278 and IEC 62279. According to these circumstances for software safety problems, we are deduced the testing items for software safety test and assessment for rail way signaling. Testing tools used for embedded software are surveyed to find a feasible safety assessment architecture. And the architecture of automatic Lest tool is proposed to test the deduced safety testing items in this paper.
