Since the FMI standard 3.0 has been released recently, it is possible that MathWorks may include support for it in a future release of Simulink.
In the meantime, if you need to use FMUs implemented with FMI version 3.0 in Simulink, you may want to consider using a third-party tool or a custom implementation to integrate the FMU with your Simulink model. There are several open-source and commercial tools available that can help you import and simulate FMUs implemented with FMI version 3.0 in Simulink.
One such tool is the FMI++ library, which is an open-source C++ library that provides an FMI-compliant API for importing and simulating FMUs. The FMI++ library supports FMI versions 1.0, 2.0, and 3.0, and it can be used to integrate FMUs with Simulink by creating a custom S-function block.
Another option is to use a commercial tool such as the Modelon Impact platform, which provides a comprehensive set of tools for importing, simulating, and validating FMUs implemented with FMI version 3.0. The Modelon Impact platform also includes a Simulink interface that allows you to integrate FMUs with Simulink models.
