Architecture Description LanguageAn information model that captures engineering information in a standardized way
Capture Specifications of Automotive Electronic Systems
Background
System Specifications - State of Practice
� Formats and specification styles are informal
� Formats and specification styles are textual
� Formats and specification styles are company
specific
� Formats and specification styles vary over time
� Different tools and approaches depending on
Domain

Model-based Analysis & Engineering of Novel Architectures for Dependable Electric Vehicles
Purpose: Refine EAST-ADL Language, tools and methodology
to support Electrical Vehicle development
Motivation
� Electrical Vehicle development and ISO 26262
require adequate engineering support
� Collaborative character of automotive industry
makes standards necessary also for
specifications
MAENAD Overview. Henrik Lönn, Volvo Technology 9
Objectives
Refine EAST-ADL Language, Tools and Methodology to
� Assist the safety process defined in the ISO 26262 safety
standard
� Provide effective prediction of quality attributes
(dependability and performance)
� Provide tool support for the automated
exploration of design spaces
(dependability, performance and cost
optimization).

EAST-ADL Association
� Non-profit, non-governmental organization
� Assist and promote the development and application of the EAST-ADL.
� The EAST-ADL Association will stipulate the content of new versions of the EAST-ADL language.
� The EAST-ADL Association has no fees or funds, and each member carry any costs for contributing.
� Membership is open to individuals and organizations
� 50 members: OEMs, Suppliers, Tool Vendors, Institutes, Academia

Finally…
� A Specification is a core asset – Shall not be tool specific
� EAST-ADL is an open, AUTOSAR-compliant representation for specifying embedded systems
� Shared ontology/terminology across companies and domains
� EAXML exchange format to secure tool interoperability
� Allows joint efforts on methodology, modelling and tools
� Supports several aspecs (timing, variability, behavior, V&V, etc. through extensions)
� EATOP open tool platform for EAST-ADL tool development
� EAST-ADL Association directs EAST-ADL evolution
