To integrate Simulink® components into third-party software, export a Simulink model as a tool-coupling functional mockup unit (FMU). When a third-party tool runs the FMU, it checks out required licenses and starts a local installation of Simulink to start the model. This function requires the Tool-Coupling Co-Simulation FMU Export for Simulink support package. Use the Add-On Explorer to download and install the support package.
