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

VEOS is a PC-based simulation platform for electronic control unit (ECU) software validation in many development stages. It lets you simulate a multitude of different models – from function models to networks of virtual ECUs, bus systems, and vehicle models – even in early phases of development.​​​​​​​

  • Simulation on Linux operating systems

    VEOS is now available for Linux operating systems (including build system and simulation).

  • Simulation of adaptive V-ECUs

    You can integrate Linux-based virtual ECUs with adaptive applications into offline simulations with VEOS on both Windows and Linux operating systems. This allows you to test ADAS/AD functions in a virtual environment.

  • General Motors: Everything Virtualized

    To increase their testing capabilities, provide faster time to market, and enable development and validation of software-defined vehicles (SDV), General Motors has decided to create a completely virtual environment, which can provide a test interface similar to a physical test system. General Motors is working jointly with dSPACE and KPIT to realize a completely virtual, cloud-capable, scalable development and integration testing environment.

  • Toyota Relies on SIL Simulation from dSPACE to Improve Electrification Development

    Of particular importance as a basis for new vehicle development is the powertrain with its corresponding ECUs. To develop and validate the powertrain, Toyota has strongly promoted the introduction of model-based development (MBD) and relies on the early use of simulation in the development process. At Toyota, SIL simulation is performed with VEOS.

Application Areas

dSPACE VEOS is a PC-based simulation platform that promotes SIL testing for the development of electronic control units (ECUs):

  • Simulating a wide range of different models, such as function models, Functional Mock-up Units (FMUs), virtual ECUs (V-ECUs), and vehicle models, in the early development stages independent of any specific simulation hardware.
  • For multi-model scenarios, VEOS supports importing, connecting, and running any number of function and plant models based on Simulink® or Functional Mock-up Interface (FMI), thereby extending the scope of the applications.

Key Benefits

VEOS runs on standard PCs, which gives function developers, software architects, and ECU testers a variety of valuable options for SIL testing during the early project phases:

  • Available for Windows and Linux operating systems.
  • Easy integration into cloud-based solutions for SIL testing.
  • Co-simulation interface to integrate third-party tools into VEOS simulation.
  • Flexible integration into the development process.
  • Software-software integration can be tested from component to system level.
  • Sophisticated environment models can be integrated with virtual ECUs to validate complex controller strategies or simulate and test entire virtual vehicles.
  • Continuity throughout the entire tool chain and easy transition from SIL to HIL testing.
  • Versatile options for integrating virtual ECUs, such as V-ECUs from different vendors or V-ECUs built for different architectures based on QEMU, etc.

Systematic Extension to the dSPACE Tool Chain

  • Open interfaces to connect and use existing tools.
  • Easy reuse of data, tools, and models between HIL simulations and SIL testing.
  • ISO 26262 certification of VEOS and other dSPACE tools makes dSPACE the world's first provider of a fully certified tool chain for validating safety-relevant automotive functions. This enables users to drive their development and approval projects in a fully certified environment, for all automotive safety integrity levels (ASILs).

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.
