Overview

Discover how the new FMI Layered Standard for Network Communication (FMI-LS-BUS), introduced by dSPACE expert Benedikt Menne, is transforming the way virtual ECUs (VECUs) are simulated. Built on FMI 3.0, this layered standard enables seamless, vendor-independent simulation of bus communication protocols like CAN, CAN FD, and CAN XL – with FlexRay, Ethernet and LIN support already in development.

Key benefits:

  • Modular simulation fidelity with High-Cut and Low-Cut abstraction layers
  • Cross-tool compatibility through industry-wide collaboration
  • Real-world validation via FMU cross-checking
  • Open-source roadmap and community-driven development

Whether you're an automotive engineer, tool developer, or simulation expert, the FMI-LS-BUS offers a flexible, future-proof solution for virtual ECU integration.

FAQ

1. What is the primary purpose of the FMI-LS-BUS?

To standardize the simulation and modeling of bus communication within FMUs to enable seamless interoperability of virtual ECUs across different tools and vendors.

2. What buses are supported in the initial FMI-LS-BUS release?

CAN, CAN FD, and CAN XL are supported in version 1.0, with FlexRay, LIN and Ethernet under active development.

3. How does the FMI-LS-BUS improve over standard signal-based FMI communication?

It provides a richer, standardized interface description, including metadata like message formats and priorities, enabling better matching and communication between FMUs.

4. Can I simulate FMUs with FMI-LS-BUS features on existing FMI simulators?

Yes, but without dedicated bus simulation features, the bus behavior might not be fully realized. Specialized simulators or additional FMUs for bus simulation are recommended.

5. How is interoperability ensured between different vendors’ tools?

Through a rigorous cross-check process where FMUs are exchanged and simulated across various platforms to validate compliance with the FMI-LS-BUS.

6. How can interested engineers or companies start using FMI-LS-BUS?

Start by reviewing the standard and implementer’s guide, experiment with demo FMUs, and engage with the FMI community via GitHub or the FMI Design Group.
