Model Design Dashboard

R2026b

Get a high-level overview of model design quality, including structure, complexity, requirements traceability, diagnostics, and reuse

Since R2026b

Description

The Model Design Dashboard helps you assess the overall quality of your model design. Use the dashboard to get a high-level overview of design size, complexity, requirements traceability, diagnostics, and reuse to identify areas for improvement. Using this app, you can:

• Assess the size and composition of your design across Simulink^®, Stateflow^®, and MATLAB^® code.

• View complexity metrics and drill down to the Model Maintainability Dashboard for detailed architecture and decision path analysis.

• Review requirements traceability, including implemented requirements, link types, and broken links.

• Check recent compile results and code issues from the MATLAB Code Analyzer.

• Identify opportunities for reuse through referenced models, linked libraries, subsystem references, and clone detection results.

Open the Model Design Dashboard App

Open a project, then use one of these approaches to open the app:

• MATLAB Toolstrip: In the Project tab, in the Tools menu, under Apps, click Model Design Dashboard.

• Simulink Toolstrip: On the Apps tab, under Model Verification, Validation, and Test, click Model Design Dashboard.

• MATLAB command prompt: Enter modelDesignDashboard.

Examples

Assess Model Design Quality

Open the Model Design Dashboard on a project.

Open the example project cc_CruiseControl.

openExample("slcheck/ExploreTestingMetricDataInModelTestingDashboardExample");
openProject("cc_CruiseControl");

Open the Model Design Dashboard.

modelDesignDashboard

The dashboard shows design quality results for the selected unit model, including the structure, complexity, requirements traceability, compile results, code issues, reuse, and clones for the model.

Version History

Introduced in R2026b

R2026b: Model Design Dashboard replaces Model Maintainability Dashboard as default dashboard

In releases before R2026b, the Model Design Dashboard button on the Project tab and the modelDesignDashboard function open the Model Maintainability Dashboard.

Starting in R2026b, these functionalities open the Model Design Dashboard instead. You open the Model Maintainability Dashboard by opening the Model Design Dashboard and then selecting Model Maintainability from the dashboard gallery.
