vVIRTUALtarget is a software that is used to generate virtual ECUs for all typical AUTOSAR-4 projects. It supports function and software developers, software integrators and test engineers throughout the entire ECU development process.
With vVIRTUALtarget, you develop and test functional software unchanged in combination with a behavioral model or with virtualized, complete AUTOSAR basic software. It enables detailed analyses by allowing you to influence the entire simulation environment in a range of different ways.
vVIRTUALtarget runs on all typical Windows PCs
Execute your software either in or independently of real time
Set up and run tests of the entire ECU software even in the absence of the target hardware – from the application software, through the AUTOSAR Basic Software and on to the hardware drivers
Modify and simulate your configuration for the real hardware
Configurations of real and virtual hardware always remain consistent
Simple connection to other test tools
System Description: Add AUTOSAR descriptions to a project
System Under Test: Setting the scope of the test
BSW Emulation: Setting options of the Basic Software emulation
Application Files: Managing the implementation files of the software components
Simulation Setup: Selection of ECU and network setups for the execution environment
Directories: Setting the locations of files belonging to the project
Testing of functional software, based on AUTOSAR 4, even during early phases
Supportive testing during design and implementation of the functional software
Testing and verification of software integration in a virtual environment
Verification of tests using virtual ECUs for re-use at physical ECUs
Highlights Version 2.0
Commissioning of functional software independently of basic software (BSW)
Automated creation of ECU configurations
Seamless client/server communication in CANoe
Even at of a very early stage, Sofftware Developers and System Integrators use the “pro” and “basic” variants for the virtual testing of functional software based on AUTOSAR 4. In the subsequent work steps, the virtual ECUs are integrated and used in test environments:
Typical user roles and software tools in a workflow with vVIRTUALtarget
You can start verifying your results with vVIRTUALtarget as early as the software component (SWC) design and development phases. The vVIRTUALtarget pro variant allows you to automate the connection of one or more SWCs to a runtime environment via your AUTOSAR interfaces. In this case, vVIRTUALtarget pro emulates the typical behavior of the AUTOSAR basic software so that you do not need to worry about configuring basic services – as in the case of ECU configuration – or about the implementation of these services – as in the case of a unit test. On the one hand, the tool delivers an automatically generated proposal for the typical management layer services while, on the other, also allowing you to determine these yourself. Thanks to this flexible approach, you can concentrate fully on the task of test implementation itself, which means, simulating the inputs to your software and observing the reactions at the outputs.
The next step is to test the entire ECU configuration as visualized in vVIRTUALtarget basic. This is done using an original target ECU configuration – again created using the designated tools from the Vector DaVinci tool suite – in order to obtain the greatest possible level of fidelity to detail. There is no need for any reconfiguration or new configuration work. The result is a binary file that you can use in your PC runtime environment, for example CANoe. In the same way as with physical EUCs, your test interfaces are network messages and I/Os.
The created virtual ECUs can be used in the cluster as well as with physical ECUs in order to test the entire system.
Usage during software development phases
When testing functional software, the focus is placed on the software components (1), individual ECUs (2) and on up to the overall system level (3):
