FMI, eFMI & SSP: The Open Standards for Simulation Interoperability
- FMI: Share and co-simulate models across tools (e.g., Dymola ↔ Simulink) using FMUs.
- eFMI: FMI optimized for real-time/embedded systems (think ECUs, robotics).
- SSP: The "blueprint" for connecting models and parameters in complex systems.
Why? Break toolchain silos, boost collaboration, and reuse models effortlessly.
- No vendor lock-in: Use any tool you like!
- Collaboration made easy: Share models across teams.
- Future-proof: Standards keep evolving with industry needs.
🤷 What is FMI?
Functional Mock-up Interface (FMI) is like a universal translator for simulation models. Imagine you build a model in Dymola, but your colleague uses Simulink, FMI lets you share your model as a Functional Mock-up Unit (FMU) so it works in their tool too!
Two Modes:
- Model Exchange: Import models directly into another tool.
- Co-Simulation: Run models together in parallel.
No more "my tool won’t open your file" headaches!

💁♀️ What’s eFMI (Embedded FMI)?
Think of eFMI as FMI’s cousin, optimized for real-time and embedded systems. Need to run a model on a tiny computer (like an ECU in a car)? eFMI makes it possible by:
- Supporting fixed-step solvers (for predictable timing).
- Working on resource-limited hardware.
Use case: Autonomous vehicles, robotics, or industrial controllers.

🙎♂️ What’s SSP?
System Structure and Parameterization (SSP) is like the blueprint/architecture for your simulation. It describes:
- How models connect (e.g., FMUs talking to each other).
- Parameters and settings (so everyone uses the same values).
A solution to avoid chaos when building complex systems!
