2021 Release Notes – FMI Toolbox 2.10

Modelon’s FMI Toolbox for MATLAB/Simulink supports all major workflows in control system development and system integration for virtual prototyping, from design and sizing to optimization and MIL/SIL/HIL validation & verification testing. The additional FMI Toolbox Coder Add-on provides extensive support enabling users to export FMUs from Simulink and import FMUs to a Simulink Coder target.

Modelon’s FMI Toolbox for MATLAB/Simulink Coder Add-on enables users to export FMUs from Simulink and import FMUs to a Simulink Coder target. Key capabilities and features related to the latest version of the FMI Toolbox Coder Add-on for Matlab/Simulink are below.


  • Added Linux and Windows support for MATLAB 2019b and 2020a.
    • Limitation: The ‘Find Nonzero Elements’ block is not supported for ME targets since 2019b.
  • Added Linux support for MATLAB 2019a.
  • Added support for building models containing FMU blocks on Linux and with MinGW.
  • Fixed bug in exported Co-Simulation FMUs that caused the internal model clock to be unsynchronized and preventing discrete and continuous states to be updated correctly.
    • Exported models may appear to have a unit delay compared to models exported in previous versions. Due to the internal model clock correction, the models are now solved accurately and values are no longer output too early. Note that this is a limitation in the FMI standard for Co-Simulation FMUs; inputs have to be delayed one sample step. This input delay may now be more apparent and must be handled appropriately by the master algorithm.
  • Other minor improvements and bug fixes.
