AUTOSAR Complexity

Motivation

AUTOSAR is influenced by many parties

Complexity is increased due to different needs

Acceptance is also increased

AUTOSAR adds complexity to the development process but offers a lot of advantages:

Interfaces offer new mechanisms for structured access of internal ECU data

Clearly defined and standardized interfaces within ECUs simplify interworking of OEMs and suppliers

Software Development

Use Cases of Virtualization

Development of functional code in a virtual environment

Integration in realistic AUTOSAR environment

Easy, mainly automated configuration

Parallel Development of test libraries for later reuse

ECU Integration

Use Cases of Virtualization

Minimum effort for parallel configuration of real and virtual target

Verification of the configuration in the virtual environment without the need for hardware

Stimulation via busses, IO and internal ports

Debugging of internal behavior is possible for the complete ECU software

System Integration

Use Cases of Virtualization

Test of distributed functions in virtual or partially virtual environment

Reuse of already configured virtual SUTs also in combination with real ECUs

Usage of test libraries developed in earlier phases

Stimulation via busses, IO and even RTE ports

Error reproduction

Use Cases of Virtualization

Reproduce functional misbehavior with measurements of field test in the virtual world

Difficultly achievable situations can be generated virtually

Simulation time is not linked to real time, so pausing and resuming when debugging is possible

Core Benefits

Summary

PC environment has advantages compared to a real HW

Better availability> Early test/integration results since the PC is always available – no need to wait

for the HW

> Easy replication of test-/integration environments on several work places

Better control> Stress scenarios can be easily applied to provoke “race conditions” and to

achieve good code coverage

> Faster execution of tests possible

> More comprehensive test automation possible since SUT can be controlled completely

> Access to internal variables at defined times possible
