It is critical to analyze characteristics of real-time embedded systems such as timing behavior early in the development. In the automotive domain, EAST-ADL is a concrete example of the model-based approach for the architectural modeling of real-time systems. The Timing Augmented Description Language v.2 (TADL2) allows for the specification of timing constraints on top of EAST-ADL models. In this paper we propose a formal validation & verification methodology for timing behaviors given with TADL2. The formal semantics of the considered timing constraints is given as a mapping to the Clock Constraint Specification Language (CCSL), a formal language that implements the MARTE Time Model. Based on such a mapping the validation is carried out by the simulation of TADL2 specifications. The simulation allows for a rapid prototyping of TADL2 specifications. The verification is performed through a mapping to Timed Automata implemented by UPPAAL. The whole process is illustrated on a Brake-By-Wire application.
