The influence of the systems architecture on the functions and other properties of embedded systems makes its high level analysis and verification very desirable. EASTADL is an architecture description language dedicated to automotive embedded system design with focus on structural and functional modeling. The behavioral description is not integrated within the execution semantics, which makes it harder to transform, analyze, and verify EAST-ADL models. Model-based techniques help to address this issue by enabling automated transformation between different design models, and providing means for simulation and verification. We present a way of integrating architectural models and verification techniques, which has been implemented in a tool called ViTAL. Consequently, ViTAL provides the possibility to express the functional EAST-ADL behavior as timed automata models, which have precise semantics and can be formally verified. The ViTAL tool enables the transformation of EASTADL functional models to the UPPAAL PORT tool for model checking. This method improves the verification of functional and timing requirements in EAST-ADL, and makes it possible to identify dependencies and potential conflicts between different vehicle functions before the actual AUTOSAR implementation.
