Verifying system behaviors in EAST-ADL2 with the SPIN model checker

EAST-ADL2 is a domain-specific architecture description language to support the model-based development of automotive embedded systems. It emerged to manage the complexity of software and electronics in advanced automotive applications. The language focuses on the structural definition for functional specifications. Behavior is defined only on the component level, in terms of functional blocks and their triggers and interfaces. The behavioral definition inside each functional block is not prescribed. This paper shows one approach to augment the language with precise syntax and semantics for behavior, and develops a procedure that transforms the composed behavioral model to the SPIN model for logic model checking. The contribution improves the modeling and verification capability of EAST-ADL2.
