Architecture Description Languages for the Automotive Domain
Abstract
The embedded electronic architecture of a modern vehicle is a distributed system composed of several tenths of nodes. The development of these systems relies on a cooperative process involving several partners (carmakers and several suppliers). In such highly competitive domain, three main factors have to be taken into account: the design and production costs, the performance, comfort, and quality of driving, and several stringent safety requirements. In order to fulfill these requirements in such a context, it is vital for the different stakeholders to master the effects of the different sources of complexity. One way to reach this goal is to provide them with a common modeling language capable of representing the system at all its design steps and a common reference architecture in terms of components and organization. This chapter illustrates this approach. It focuses on EAST-ADL, an architecture description language dedicated to the automotive domain. Its links to the reference architecture defined by the AUTOSAR consortium are given. The chapter focuses especially on the ability offered by EAST-ADL to support the validation and verification (V&V) activities in order to fulfill the safety requirements.
