With BlockImporter for Simulink you can:
Validate your Simulink models
Frequently, engineers get Simulink models that were developed by other groups or external organizations, and the first step in adopting these models is to ensure their correctness before extensive simulations are performed. Pulling apart and validating these complex models is a tedious, manual process.
BlockImporter allows you to import system and subsystem models and study the underlying mathematics in a meaningful, fully understandable form. You can also test the behavior of the model by running simulations and parameter sweeps.
