Organize Architectural Data

Organize System Composer™ architectural data using Simulink® projects, data dictionaries, and model comparison

You can use many tools to manage and support complex System Composer workflows. Learn how to use Simulink projects to manage files and settings and to interact with source control. Reuse interface definitions across architecture models with data dictionaries and referenced dictionaries to share and store data across models. Compare System Composer model and model artifact differences using the Comparison Tool.
