Abstract:The architectural description language for automotive embedded systems EAST-ADL is presented in this paper. The aim of the EAST-ADL language is to provide a comprehensive systems modeling approach as a means to keep the engineering information within one structure. This facilitates systems integration and enables consistent systems analysis. The EAST-ADL encompasses structural information at different abstraction levels, requirements and variability modeling. The EAST-ADL is implemented as a UML2 profile and is harmonized with AUTOSAR and a subset of SysML. Currently, different ways to model behavior natively in the language are investigated. An approach for using SysML parametric diagrams to describe equations in composed physical systems is proposed. An example system is modeled and discussed. It is highlighted that parametric diagrams lacks support for separation between effort and flow variables, and why this separation would be desired in order to model composed physical systems. An alternative approach by use of SysML activity diagrams is also discussed.
