Résumé
We study the use of formal modeling and verification techniques at
an early stage in the development of safety-critical automotive
products which are originally described in the domain specific
architectural language EAST-ADL2. This architectural language only
focuses on the structural definition of functional blocks. However,
the behavior inside each functional block is not specified and that
limits formal modeling and analysis of systems behaviors as well as
efficient verification of safety properties. In this paper, we
tackle this problem by proposing one modeling approach, which
formally captures the behavioral execution inside each functional
block and their interactions, and helps to improve the formal
modeling and verification capability of EAST-ADL2: the behavior of
each elementary function of EAST-ADL2 is specified in UPPAAL Timed
Automata. The formal syntax and semantics are defined in order to
specify the behavior model inside EAST-ADL2 and their interactions.
A composition of the functional behaviors is considered a network of
Timed Automata that enables us to verify behaviors of the entire
system using the UPPAAL model checker. The method has been
demonstrated by verifying the safety of the Brake-by-wire system
design.
