Abstract [en]

EAST-ADL is an architecture description language (ADL) for model-based development of automotive embedded systems.The formalization of domain-specific engineering information and methodology brings a potential for a wide range of benefitsfor information management, system design and integration, tool interaction, documentation and communication. This paper describesthe EAST-ADL language support for safety requirements, faults/failures, hazards and safety constraints in the context of ISO/DIS 26262reference safety lifecycle. Based on the language support, the safety related information can be derived and managed seamlessly alongwith its target nominal system architecture model with multiple abstraction levels and view extensions. Through model transformationand tool integration, automated safety analysis is allowed.

EAST-ADL ist eine Architekturbeschreibungssprache (ADL) fu¨ r die modellbasierte Entwicklung von eingebetteten Systemen im Bereichder Fahrzeugtechnik. Die Formalisierung von Doma¨ nen-spezifischen Informationen und Methoden bringt einen Mehrwert fu¨ r einebreite Palette von Anwendungen in den Bereichen Informationsmanagement, Systemdesign und Integration, Toolketten,Dokumentation und Kommunikation. Diese Publikation beschreibt die EAST-ADL-Unterstu¨ tzung fu¨ r Sicherheitsanforderungenund -bedingungen, Gefahren, Fehler und Sto¨ rungen im Kontext des ISO 26262-Phasenmodells. Basierend auf dieserSprachunterstu¨ tzung ko¨ nnen sicherheitsbezogene Informationen abgeleitet und nahtlos mit dem dazugeho¨ rigen Architekturmodellverwaltet werden. Dieses beru¨ cksichtigt verschiedene Abstraktionsebenen und Sichtweisen. Die Modelltransformation und Integrationverschiedener Softwarewerkzeuge erlaubt so eine automatisierte Sicherheitsanalyse.
