Abstract
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.
