Developing and Testing Virtualized AUTOSAR Software
vVIRTUALtarget is software for virtualizing individual software components and fully configured ECUs for all typical AUTOSAR projects. It supports function and software developers, software integrators and test engineers throughout the entire ECU development process.
With vVIRTUAltarget you create virtual Systems Under Test (SUTs) for both AUTOSAR Classic and AUTOSAR Adaptive:
AUTOSAR Classic has been the established standard for use in signal-based applications for many years.
AUTOSAR Adaptive, on the other hand, concentrates on the service-oriented architecture as it will be increasingly used in future projects.
Both architectures complement each other and are used depending on the application.
vVIRTUALtarget runs on all typical Windows PCs
Runs software in real time or independently
Setup and testing:
... of individual software components with abstracted basic software
... of the entire ECU software even without target hardware − from the application software to the AUTOSAR basic software to the hardware drivers
Stimulation and monitoring of ECU-internal variables
Modifing and simulation of configurations for realhardware
Always consistent configurations of real and virtual hardware
Easy coupling to other simulation and test tools
In this short video you will learn how to develop and test AUTOSAR ECU software faster and more relaxing - namely virtual - with vVIRTUALtarget. Join our two engineers and see yourself. (2:36 min)

vVIRTUALtarget "Basic" and "Pro" for AUTOSAR Applications
The vVIRTUAltarget variants "basic" and "pro" support you in creating virtual Systems Under Test (SUTs) for AUTOSAR Classic as well as for AUTOSAR Adaptive:
AUTOSAR Classic is the standard that has been established for many years for use in primarily signal-based applications. vVIRTUALtarget supports you from the early stages of development and testing of software components through to the integration of complete ECUs, including the AUTOSAR basic software.
AUTOSAR Adaptive on the other hand, focuses on the service-oriented architecture that will be increasingly used in future projects. vVIRTUALtarget allows you to conveniently develop your AUTOSAR Adaptive application on your familiar Windows operating system and test it with CANoe.
Both AUTOSAR architectures complement each other and are used in combination with vVIRTUALtarget basic or vVIRTUALtarget pro depending on the application:
Virtual functional SWCs
Applications and configurations of the AUTOSAR Runtime for Adaptive applications (ARA) in a virtual environment
Classic + Adaptiv
Complete system with virtual and real ECUs
Typical user roles and tools when using vVIRTUALtarget in an interlocked development process from first software components (SWCs) up to a real ECU ready for SOP.
Development Workflow of AUTOSAR Classic ECUs with vVIRTUALtarget Basic/Pro
The basic and pro variants are used by software developers and integrators for virtual testing of functional software based on AUTOSAR 4 from a very early prototype stage.
In subsequent work steps, the virtual ECUs are integrated into test environments and used.
Important Development Phases
1) Function Development
Development and testing of AUTOSAR Software Components (SWCs) in early development stages
Already in the design and development phases of AUTOSAR SWCs you can start testing your results with vVIRTUALtarget pro. This variant offers you the option of automatically connecting individual or multiple SWCs to an execution environment using their AUTOSAR interfaces. The typical behavior of an AUTOSAR base software is emulated by vVIRTUALtarget pro, so you do not have to worry about configuring base services.
However, vVIRTUALtarget pro also gives you the freedom to set typical services for controlling the management layer yourself. This can be, for example, the wake-up behavior of the ECU or the assignment of AUTOSART runnables to AUTOSAR tasks. This flexible approach allows you to fully concentrate on the actual application development and test implementation:
i.e. stimulate the inputs of your software
observe the reaction of the software at the outputs
2) ECU Integration
Development and testing of ECUs with basic software
In the next step, you test the application and the configuration of the entire ECU virtualized with vVIRTUALtarget basic or vVIRTUALtarget pro:
The DaVinci Configurator Pro tool, allows you to configure your basic software and reuse the non-hardware related element one-to-one for the virtual ECU. The hardware related parts are replaced for your virtual ECU. However, a reconfiguration or even a new configuration is not necessary, because the virtual elements are derived from the real parts. The result is a binary file that you can use in your PC execution environment, for example in CANoe. Your test interfaces are, here analog to real ECUs, the network messages and I/Os.
In addition, vVIRTUALtarget pro offers you the possibility to stimulate or observe AUTOSAR port interfaces that are not assigned to bus signals.
The virtual ECUs created can be used in a network as well as with real ECUs to test an entire system.
