Banci M., Becucci M., Fantechi A., Spinicci E. Validation Coverage for a Component-based SDL model of a Railway Signaling System. In: International Workshop on Test and Analysis of Component Based (Barcelona, Spain, 27-28 March 2004). Proceedings, vol. 116 pp. 99 - 111. M. Pezz (Ed.) (ed.). ENTCS, Elsevier, 2005.
In this paper we present an application of formal verification techniques to a component-based SDL model of a railway signalling system lent by General Electric Transportation Systems. A MSC-driven validation technique has been applied to verify the multiple-configuration features of the system. This work addresses the problem of validating a component-oriented designed SDL model, with a partial reuse of previously verified MSC scenarios if a new component is introducing or modified: some possible solutions based on the coverage metrics and information provided by the adopted tools are discussed.
