Software tool speeds development of AUTOSAR-4 projects

vVIRTUALtarget is a tool for virtual testing of AUTOSAR ECUs from Vector. It enables faster software development implementations in typical AUTOSAR-4 projects. The virtualised environment makes it possible to test the ECU software throughout the development process. Users benefit from rapid test execution that can be even faster than in real time.

This software tool generates virtual ECUs for all typical AUTOSAR-4 projects. It supports functional and software developers, software integrators and test engineers over the entire development process for their ECU software. The focus is on developing and testing functional software, unmodified, in mutual interaction with a behavioural model or with virtualised, complete AUTOSAR basic software. Since vVIRTUALtarget only requires a typical Windows PC, a stand-alone test environment can be implemented economically at every workstation and is easy to archive and replicate.

Above all, the test results do not necessarily have to depend on the execution speed of a test system. That is because the simulation does not need to be coupled to real time, rather just to a consistent simulation time.

On the other hand, a simulation may also be executed in real time, which permits coupling with real hardware such as sensors, ECUs and HiL systems.

With the “pro” product variant the application software can already be tested efficiently starting in the early design phase. Individual or multiple software components can be integrated into an execution environment automatically via their AUTOSAR interfaces.

vVIRTUALtarget pro emulates the typical behaviour of AUTOSAR basic software here. Users do not need to additionally configure or implement a substitute (“stub”) for modules in the basic software.

In addition, users get work relief from automatically generated recommendations for typical AUTOSAR Service Layer configurations, which you may, however, set up yourself.

In the next development step, the “basic” product variant performs virtualised testing of the configuration and the software of the entire ECU. Here, the original configuration of the target ECU is used, and early testing of its proper functionality is made possible. The results are reused in a PC execution environment with CANoe.

Virtual ECUs can also be used in combination with other virtual and real ECUs to test a total system.
