EAST-ADL
 | This article needs additional citations for verification. (April 2008) |
EAST-ADL is a modeling language defined as a domain-specific language to allow the development of automotive electronic systems. The modeling element consists of different entities to describe features, requirements, verification and validation, variability, software and hardware components. Furthermore it includes specific annotations linked to models to perform later analysis of the global system.
The master concept of the organization of EAST-ADL is the abstraction levels to perform the description of the models in different stage of the development, to reflect the details of the engineering development with associated models of the function and the overall architecture. This concept allows functional decomposition of the functions, starting form abstract representation as model, supporting analysis and design engineering phase to finally support implementation with software and hardware component.
The language is aligned with Automotive standard AUTOSAR, in such as implementation level is defined in AUTOSAR.
The EAST-ADL language has been defined in two steps
- ITEA EAST-EEA ITEA project ([1]), that defined basics of the language
- IST FP6 ATESST project ([2]), that extend and aligned the language to standardization initiative (AUTOSAR, SySML, UML..)
