Large-scale modeling projects can be organized into components to facilitate team-based development, project reuse, unit testing, and independent release of components. Simulink supports project componentization through project referencing. A project reference hierarchy can be created by referencing other projects from a parent project. You can explore the full project reference hierarchy, access all associated files, monitor their statuses, and track changes of any referenced project directly from your Simulink project.
