Model Comparison

Compare models to identify changes or merge differences between models

Use the Comparison Tool and Three-Way Merge Tool to compare Simulink^® models and review, merge, and save changes. Compare templates for models and projects. Resolve conflicts in models under source control, and customize the diff and merge process when you use external source control tools. For more information, watch Using Projects to Collaborate, Track, and Merge Changes and Perform Code Reviews (4 min, 50 sec).
