Current development trends in automotive software include increasing standardization of the embedded software structure. However, controlling the system definition and managing its complexity remains the critical issue of engineering information management. System modeling based on an Architecture Description Language (ADL) is an effective way to keep these assets within one information structure.

The original EAST-ADL was developed in the EAST-EEA project and basic concepts were reused in the AUTOSAR standardization initiative. It has been refined in the ATESST project to EAST-ADL2. This paper presents the results of the language extension provided by the EAST-ADL2 domain model and focuses on its possible extension of the AUTOSAR standard to support decomposition of E/E automotive systems.
