Comprehensive Approach

Early Development Phases

Analysis on two levels:featuresstructural functional analysis

Design

corresponds to other standards with early development coverage:e.g. ISO26262 with Functional Safety Concept

Data exchange over ports Allocation

Structure

Core vs. Extensions.

Extensions only point to Core and other extensions!

Common principle for all extensions:1 Extension Container + n supplmenetary elements.

EAST-ADL Association

before:various research projects used & evolved

EAST-ADLad-hoc synchronization

now:EAST-ADL Association ...1. to coordinate efforts

(not to do main actual work)2. single point of entry for information

Solution

upcoming version 2.1.11 (or 2.2 ??)stable releaseintended for use for next 12-18 monthsplanned for end of Nov/Dec 2012

later changes:take evolution into accountdocument how to translate to new version

16

Change „Process“

Add newinformation as

User Attributes.

Define UML2 Profilebased on

EAST-ADL Profile.

Modify tool-basedEAST-ADL implementation

(eg. MetaEdit+).

Updated / AddedExtension in
