Implementation of Boundary Value Analysis Tool for Software Verification in Railway Signaling Systems

The railway signaling system is being converted to the computer system from the existing mechanical device, and the dependency on software is being increased rapidly. Though the size and degree of complexity of software for railway signaling system are slower than the development speed of hardware, it is expected that the size will be grown bigger gradually and the degree of complexity will be increased also. Accordingly, the validation of reliability and safety of embedded software for train control system was started to become influential as the important issue. In this paper, we presented boundary value analysis tool for railway signaling system software, and presented its result of implementation.
