Domain
• EAST-ADL: approach to describe automotive electronic
systems though an information model in standardized
form
• Aspects covered: vehicle features, functions, requirements,
variability, software components, hardware components,
communication.
• Four levels of abstraction
• Complements AUTOSAR at higher levels of abstraction

EAST-ADL background
• Vehicle electronics’ complexity increases
• Engineering errors can be costly/threat to safety
• Improved engineering methods desirable
• EAST-ADL: standardized modeling approach
• Architecture Description Language: information model that
captures engineering information in a standardized way
• EAST-ADL as a suggested reference
• Companies may freely choose to use a subset of EAST-ADL, or
tailor chosen aspects to their specific needs

EAST-ADL modeling approach
• Layers of abstraction
• Vehicle level: features observed from the outside
• Analysis level: abstract functionality of components
• Design level: concrete functions, allocation to hardware
• Implementation level: AUTOSAR components
• Extensions, enabling
• Requirements
• Variability
• Verification & validation

EAST-ADL tool support
• Generally limited tool support
• Eclipse/Papyrus (open source, plugins closed-source)
− UML2 profile with Eclipse plugins extending Papyrus
− Buggy, fragile even, but has some demonstrative use
• MetaCase: MetaEdit+ (commercial)
− Seemingly stable, fully compatible
− Authors active in EAST-ADL organization
• PREEvision (commercial)
− Huge platform able to describe all EE aspects of vehicles or even
airplanes

Project goals
• (1) Relate CARM 2G architecture & concepts to EASTADL
• How can we re-model CARM models using EAST-ADL?
• (2) Determine ontological commitment of EAST-ADL to
CARM domain
• How well suited is EAST-ADL to model problems in the
CARM domain?
• (3) Devise model transformation CARM 2G  EASTADL
• Can we come up with some automated transformation to
take care of re-modeling?

Ontological commitment
• Determine ontological commitment of EAST-ADL for
CARM 2G domain
• Ontological commitment captures how well an ontology (or
metamodel) fits its problem domain
• Research/define suitable metrics
• Carry out analysis, analyze metrics
• Find deficiencies/points of improvement

Model transformation
• Define CARM 2G languages in terms of EAST-ADL
• Relate CARM 2G and EAST-ADL metamodels
• Using results, combined with those from (1), examine
relevant model transformations
• If feasible, implement them using QVTO

Status
• What’s done?
• Studied EAST-ADL in detail
• Developed example models in EAST-ADL (MetaEdit+,
Papyrus, PREEvision)
• Defined project scope and approach
• What’s next?
• Remodel CARM 2G case studies in PREEvision
• Relate CARM 2G concepts to PREEvision metamodel
concepts
• Based on the analysis results, next steps will be decided
