Platform for PC-based simulation of models and ECU network communication

VEOS is a PC-based simulation platform for validating the software of electronic control units (ECUs) in early development process stages. A wide range of models - function models, virtual ECUs, bus systems, and plant models - can be simulated with VEOS independently of any specific simulation hardware.

  • Cluster Simulation for Highly Automated Test Drives

    For driving millions of kilometers on your PC, you can set up as many VEOS instances in one cluster as needed for the parallel execution of virtual test drives.

  • Functional SIL stations at BMW

    The higher the number of people involved in the development of ECU software, the more important it is to test the individual components early and realistically. BMW has chosen dSPACE VEOS as their central, PC-based simulation platform.

  • AUTOSAR simulation with VEOS

    The Ford Motor Company needed a tool chain that on the one hand accelerates the development process to meet customers’ expectations and on the other hand reduces the time and effort required by new adopters to familiarize with its methods. With the dSPACE virtual validation tool chain, they found both.

  • Euro NCAP Tests with Virtual Test Drives

    As customer expectations rise and Euro NCAP requirements get tougher, the cost of developing advanced driver assistance systems threatens to become unmanageable. dSPACE offers the solution: a well-coordinated tool chain for function development, virtual validation and hardware-in-the loop simulation.

Application Areas

dSPACE VEOS is a PC-based simulation platform that promotes the use of virtual validation in the development of electronic control units (ECUs). VEOS makes it possible to simulate a wide range of different models − function models, Functional Mock-up Units (FMUs), virtual ECUs (V-ECUs), and vehicle models – independently of any specific simulation hardware in early development stages.
For multi-model scenarios VEOS supports importing, connecting and running any number of functions and plant models based on Simulink or Functional Mock-up Interface (FMI) thereby extending the scope of your applications.

Key Benefits

Running on a standard PC, VEOS gives function developers, software architects and ECU testers numerous new options for virtual validation in an early project phase.

  • Software-software integration can be tested from the component to the system level.
  • Sophisticated environment models can be integrated with virtual ECUs to validate complex controller strategies or simulate and test entire virtual vehicles.
  • In preparation for hardware-in-the-loop simulation, models and tests can be created, set up and run on a PC independently of the hardware-in-the-loop (HIL) system.

Systematic Extension to the dSPACE Tool Chain

VEOS works hand in hand with other dSPACE products to provide a complete tool chain for the development and testing process. This means that tools and models which are commonly used in rapid control prototyping and hardware-in-the-loop simulation can also be used in the virtual world. Similarly, layouts from HIL simulation can be reused in PC-based simulation with VEOS and vice versa. VEOS also provides open interfaces to connect and utilize your existing tools.

Cooperation with The MathWorks

VEOS is part of the MathWorks Connections Program. dSPACE works closely together with MathWorks to make sure that C code generated with the Simulink® Coder™ can be integrated and simulated with VEOS.

Convenient Model Exchange

To make exchanging simulation models easy, dSPACE offers a Model Interface Package for Simulink® (MIPS) for generating Simulink implementation container (SIC) files.
With the free-of-charge MIPS, modeling experts can generate the (C code) SIC file with Simulink Coder, without needing a VEOS or ConfigurationDesk license. Out of their Simulink models and together with dSPACE Run-Time Target, they can generate code and create ZIP files that contain all the necessary code and artifacts for executing the models on different simulation platforms, such as VEOS and SCALEXIO®.
Model integrators using SIC files do not have to generate code again for building the simulation. Using SICs therefore significantly reduces the amount of time needed for reusing the SICs in different projects.

Efficiently Integrating Various Modeling Approaches

Compliance with FMI ensures that models created in various modeling tools can be exported as Functional Mock-up Units (FMUs) and that these FMUs can readily be integrated in VEOS-based virtual validation projects. In such projects, FMUs can be integrated together with other FMUs, virtual ECUs (V-ECUs), and Simulink® models. The user workflow for importing and connecting FMUs to other model interfaces is identical for all supported model types. Variable and parameter access during simulation is supported by ControlDesk, AutomationDesk and XIL API.

Functional Mock-up Interface

dSPACE supports the open FMI standard for an easy integration of simulation models from various sources.

Support of Multisensor Applications

VEOS supports bidirectional, low-latency communication with RTMaps, the component-based software development and execution environment from Intempora.
