The acronym EAST-EEA stands for Electronics Architecture and Software
Technologies ??” Embedded Electronic Architecture [13]. It is a project of the
European ITEA ( Information Technology for European Advancement ) program.
The results of this project form the basis for AUTOSAR.
The participants in EAST-EEA include car manufacturers and suppliers. The
EAST-ADL ( Architecture Description Language ) was born within the scope of
this architecture. ADL is a profi le of UML2 for modeling of electronic systems in
the automotive fi eld. It focuses on requirement modeling, consistency across several
abstraction levels as well as validation and verifi cation. EAST-ADL is organized
in six areas:
1. Structure
2. Behavior
3. Requirements
4. Validation and verifi cation
5. Support
6. Variants
Language constructs are available for each of these areas.
This results in considerable overlapping with the capabilities and goals of the
SysML language. Some initiatives have been started to bring the two languages
closer together. For example, the requirement modeling of EAST-ADL is an extension
of the SysML approach, but based on SysML Version 0.
