Impact analysis helps you manage large modeling projects and makes it easy to analyze the structure and dependencies in your Simulink® Project. After performing dependency analysis, you can visualize the project content and relationships among all the files in your project. Starting with Release 2018a, impact analysis allows you to identify dependencies at a finer level of granularity, not only at the file level, but also between individual requirements and blocks in your model. With this feature, you can now easily identify impacts of changing a single block or a requirement in your Simulink Project.
