Simscape Language Support

The Simscape™ language extends the Simscape modeling environment by enabling you to create new components that do not exist in the Foundation library or in any of the add-on products. It is a dedicated textual language for modeling physical systems. The Simscape language lets you define custom components as textual files, complete with parameterization, physical connections, and underlying equations. The components you create can reuse the physical domain definitions provided with Simscape to ensure that your components are compatible with the standard Simscape components. You can also add your own physical domains and provide complete component libraries for these domains. You can deploy the textual component files in block diagrams by converting them into custom Simscape blocks. For more information, see What Is the Simscape Language? (Simscape).

The tables list the Simscape Hardware-in-the-Loop (HIL) Workflow support for the Simscape language for different solvers.
