AUTOSAR in short

Mentor Graphics and VSx introduction— Vehicle Systems Architect— Vehicle Systems Integrator— Vehicle Systems Test

AUTOSAR objectives

AUTomotive Open System Architecture — A gigantic project to solve the accumaled problems in

the automotive industry

The main problem:— The huge competition forces the car OEM-s to introduce

new model in every 2-3 years (But they are not able to do it)

— To develop the new car model is a huge investment and big engineering effort Big complexity High volume and Functional safety

AUTOSAR defined solutions

The identified solution — Support for model based design

Existing models and modelling tools are supported— Matlab Simulink / UML design tool

Methodolgy and tools are defined for an unbraked design flow

— Support for re-usage of existing components Re-usage of application dependent components

— SW Components, Compositions Re-usage of application independent platform

specific components— Basic SW modules

Principles of the Mentor VSx Tool Suite Design Process covered by a set of point tools,

deployable step by step, according to customers needs.

Supporting:— early verification and late binding of solutions

as opposed to the more common “early binding / late verification” style.

— Real industrial development process Parallel Processes Iterative development Distribution of Roles and Responsibilities

in today's multi-company, modular supply chain

Based on standards as AUTOSAR and EAST-ADL

Enable shifting validation effort from physical prototypes to a virtual environment

Implementation aspects

Based on the Eclipse framework— All VSx tools are Eclipse ”plugins”

The VSx infrastructure adds AUTOSAR awareness on top of Eclipse

Open interfaces to enable integration with other tools, thirdparty or customer specific

VSA VSI

VSBBSW

Volcano VSA The VSA is system design tool

with focus on architecting an AUTOSAR based system of ECUs, communication networks, sensors and actuators.

The inital version of VSA is focused on designing/configuring AUTOSAR systems

Coming versions of VSA will support electronic and SW architecture design further with features like CPU and memory load assesment for ECUs, version and variant handling, as well as non-AUTOSAR systems

VSA

Multi-user work with Team

VSA utilises the Eclipse ”Team interface” to connect to industry standard CM systems such as

— Clearcase— SVN— CVS— ...

Team enables multi-user development work according to the capabilities of the selected CM system

VSA Merge Tool

Target object

Source objectMerger Toolbar

The VSA merge tool allows merging objects that has been updated by different sources

— Enables iterative development in separate tools— Enables merging data modified by supplier or OEM respectivly

VSA Merge Tool Displays difference of objects and allows

merging selected elements and properties

AUTOSAR timing

A full system timing model covering from sensor read to actuator effect

Based on defining events and timing requirements between the events

VSIVehicle Systems Integrator

VSA VSI

VSBBSW


Virtual Systems Integrator

Validate SWC/composition behavior at VFB level

Design verification and validation of embedded software from multiple sources in distributed systems

AUTOSAR is initial target IDE, debugger and profiler in

AUTOSAR environment, etc

Why an AUTOSAR System Level Simulator?

AUTOSAR SWCs coming from different sources must be integrated to perform vehicle functionality

Allows verification of SWC compositions long before ECUs are available

Benefits of an AUTOSAR System Simulator Excellent Collaboration

— OEM and Tier1 communicate around executable models— Achieve early specifications

Required functionality is communicated unambiguously,before architectural decisions are made

— Achieve early integration and test Specifications with integrated functions and verification suites

increase chances of first-time success

Verification is fast and accurate— Simulates at a high-level of abstraction

Integrate functions from multiple tools— Functionality is best expressed in multiple domain-specific modeling

languages

Use native modeling tools— Developers remain in familiar tools, preserving investments into

existing tools and libraries

What is Volcano Vehicle Systems Tester (VST)

■ One single environment for AUTOSAR Basic SW Test design, execution and reporting

■ Executes the standardized AUTOSAR conformance test suite

■ A generic TTCN-3 SW module test environment with AUTOSAR as speciality

■ Probably the quickest way of verifying AUTOSAR BSW modules - on target or in a PC environment!
