EAST-ADL 2.0 Specification
- 2008
-
Rapport (refereegranskat)abstract
- This specification of the EAST ADL 2.0 is based on the EAST-ADL developed in the EAST EEA projectand has been further refined and harmonized with on-going modelling appraches in the automotiveindustry. It presents the modeling infrastructure, i.e. how the modeling elements should be represented inthe language and the UML representation. For each package a usage example is provided.The EAST-ADL 2.0 is harmonized with AUTOSAR.The metamodel and UML profile of EAST ADL 2.0 is defined in two steps: A domain (automotive)metamodel is defined, capturing only the domain specific needs of the language, without adding the UML2details. The basic concepts of UML are used for this purpose, such as classes, compositions andassociations. Based on the domain metamodel, a UML2 profile for the domain metamodel is defined,specifying stereotypes with properties and constraints.Comments on the content of this document are welcomed, and should be directed to .Please download the latest available specification and the XMI file ready for use in UML2 tools from the website.

Konferensbidrag (refereegranskat)abstract
- The future de-facto standard for automotive electric/electronic (E/E) architectures, AUTOSAR (1), is becoming more and more mature. In December 2007 there has been a release of the version 3.0, and automotive OEMs are already using AUTOSAR technology in their series production projects. Even though there has been an evolution of which engineering information and concepts are part of AUTOSAR and there are still things to be defined, there will always be a number of issues outside the scope of this standardization initiative. As AUTOSAR has become a de facto standard, there is an obvious possibility now to define general systems engineering concepts complementary to and thus going beyond the current AUTOSAR specifications. In this paper we describe the advantages of having an integrated architecture description language (ADL) specific for the development of E/E systems in the automotive domain. We present the core concepts for such an integrated ADL which targets an overall systems engineering approach: the EAST-ADL2. The original EAST-ADL was developed in the EAST-EEA project (7) and basic concepts were reused in the AUTOSAR standardization initiative. Lately, the original EAST-ADL has been refined and extended in the ATESST project (www.atesst.org) to EAST-ADL2. The EAST-ADL2 conceptually integrates and links engineering information related to multiple engineering disciplines such as product line engineering, requirements engineering, control engineering, software engineering, safety engineering and real-time systems engineering. The ADL docs not prescribe a specific development process and it lends itself to top-down, bottom-up and middle-out development approaches and methods. As a central part, the EAST-ADL2 defines a system model which is organized in parts representing different levels of abstraction, reflecting different views and levels of details of the vehicle E/E architecture. By identifying AUTOSAR as belonging to only one certain level of abstraction, namely the implementation level, we also show that there is a way to define complementary ADL concepts without interfering with AUTOSAR. These describe engineering information that is more abstract, with different engineering focus and thus - from the EAST-ADL2 perspective - on different levels of abstraction.

Managing Complexity of Automotive Electronics Using the EAST-ADL

Konferensbidrag (refereegranskat)abstract
- The complexity of embedded automotive systems calls for a more rigorous approach to system development compared to current state of practice. A critical issue is the management of the engineering information that defines the embedded system. Development time, cost efficiency, quality and dependability all benefit from appropriate information management. System modeling based on an architecture description language is a way to keep the engineering information within one information structure. The EAST-ADL was developed in the EAST-EEA project (www.easteea.net) and is an architecture description language for automotive embedded systems. It is currently refined in the ATESSTproject (www.atesst.org). This paper gives an overview of the EAST-ADL and accounts for some recent refinements as developed in the ATESST project. Areas covered include the relation to other standardization initiatives such as UML2.0, AADL, AUTOSAR, SysML, Marte profile, requirements management and variability.

Konferensbidrag (refereegranskat)abstract
- The complexity of embedded automotive systems calls for a more rigorous approach to system development compared to current state of practice. A critical issue is the management of the engineering information that defines the embedded system. Development time, cost efficiency, quality and most importantly, dependability, all benefit from appropriate information management. System modeling based on an architecture description language is a way to keep the engineering information in one information structure. The EAST-ADL was developed in the EAST-EEA project (www.east-eea.org) and is an architecture description language for automotive embedded systems. It is currently refined in the ATESST project (www.atesst.org). This chapter describes how dependability is addressed in the EAST-ADL. The engineering process defined in the EASIS project (www.easis-online.org) is used as an example to illustrate the support for engineering processes in EAST-ADL.
