Towards the Analysis and Verification of EAST-ADL Models using UPPAAL PORT

A system’s architecture influence on the functions and other properties of embedded systems makes its highlevel analysis and verification very desirable. EAST-ADL 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 address this issue by enabling automated transformation between different design models, and providing means for simulation and verification. We present a verification tool, called ViTAL, which 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 EAST-ADL 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.
