New bus architectures and complex networks in bus communication increase the importance developing and testing the bus and network communication. That is why dSPACE provides a comprehensive and complete tool chain for simulating, analyzing, and validating networks. As dSPACE has been an active part of standardization bodies from the beginning we provide you with long-standing experience.



Our Solution Highlights
  • Real-time simulation tools and hardware for mobile and laboratory use
  • Completely virtual simulation for buses
  • Native support of several bus interfaces, easy to configure and extensible
  • Support of standard bus systems for all domains and application areas such as automotive, aerospace, industrial, or off-highway

Bus & Network Simulation

  • Comprehensive hardware and software portfolio, for example for rapid control prototyping and hardware-in-the-loop and software-in-the-loop simulations.
  • Simulation platforms for testing bus and network systems are tailored to your specific project needs, ranging from slow to very fast bus systems
  • Standardized solutions for all common automotive bus systems, such as CAN, CAN FD, LIN, Ethernet, and FlexRay.
  • Customer-specific solutions for additional bus systems, such as ARINC 429, ARINC 664, MIL-STD-1553, Profibus, and EtherCAT.

Bus & Network Logging and Replay

No matter your specific requirements, dSPACE offers the ideal system.

  • For applications requiring a high data bandwidth, AUTERA is the right choice. With an in-vehicle data logging and prototyping system, you can read, process, and record raw network data from lidar, radar, and camera sensors as well as other automotive buses and networks with best-in-class bandwidth.
  • If you are running SCALEXIO, you can directly access the CAN, LIN, or Ethernet system interfaces without additional hardware. This makes it easy to analyze your signals without a complex and costly test setup.
  • In software-based simulation runs, for example, with dSPACE VEOS, you can also access the network interfaces directly.
  • A direct connection between your PC and an ECU is provided by the specialized converters for various bus protocols, such as CAN, LIN, and K-Line. These converters (DCI-KLine1, DCI-CAN/LIN1, DCI-CAN2) allow you to analyze your signals even without a real-time system.
  • For in-vehicle applications, you can use the MicroAutoBox III as a bus and network gateway and for monitoring purposes. The MicroAutoBox III is a powerful real-time system for performing fast, in-vehicle function prototyping. It can be added to or replace an electronic control unit (ECU) and lets you experience and test control features in a real environment.

All systems are part of a complete and consistent tool chain. For example, the bus simulation container allows you to reuse your bus configuration together with the environment model on many dSPACE platforms without having to adapt your bus interfaces.

Working with Communication Description Files

Working with Communication Description Files

For special tasks such as analyzing communication description files, dSPACE offers a dedicated solution: the Communication Matrix Manager.

The Communication Matrix Manager is a stand-alone software for handling communication matrices intuitively, quickly, and affordably. It supports the communication standards Ethernet, FlexRay, CAN, and LIN.  The software provides graphical representations of the content in conventional communication matrix formats (AUTOSAR, FIBEX, DBC, LDF). The representation is independent of the communication matrices and includes a hierarchical view of the different elements, the properties of the elements, filters, and dedicated views. You can easily compare the properties from many different communication matrix elements, for example, clusters, channels, ECUs, PDUs, originating from several communication matrices, thus finding deviations quickly and intuitively. The software makes detecting changes and performing consistency checks easy and user-friendly.

Supported Standards for Network Communication

Supported Standards for Network Communication

  • ARXML: Files describe systems according to AUTOSAR to describe different bus protocols, including the gateways.
  • FIBEX: Fieldbus Exchange Format specified by ASAM containing information about the complete vehicle network.
  • DBC: Communication database for CAN describing the communication between distributed ECUs.
  • LDF: LIN description file specifying all the signals, data packages and scheduling tables of a LIN bus.
  • SAEJ1939: Vehicle bus standard is based on CAN and used for communication and diagnostics among vehicle components
