Abstract : This paper presents and compares two model-based approaches to ensure the dependability of a rail system in the context of ERTMS (European Rail Traffic Management System). V&V activities against safety properties are carried out by simulating train operations on State machine models of railway infrastructures. This paper presents this approach by means of a comparative study between two tools which analyze the models with various verification strategies. The tools used are Matlab Simulink environment and the DIVERSITY symbolic execution tool from CEA LIST.
