Diagnostics

View diagnostics for models, Configure and customize diagnostic checks, Understand diagnostic viewer layout

Simulink^® provides diagnostic messages when certain conditions are detected during a Simulink operation on a model. The diagnostic messages are captured under error, information, or warning categories.

The diagnostic messages encountered during a command-line operation are displayed on the command prompt while that encountered during a Simulink user interface operation are displayed in the Diagnostic Viewer user interface. For example, if you use the command Simulation > Run to simulate a model, the diagnostic messages are displayed in the Diagnostic Viewer but if you use the command sim(bdroot) in MATLAB^® command prompt to simulate a model, the diagnostics messages are displayed in the command prompt.

You can customize the diagnostic messages, and also customize the conditions the software checks to either produce errors or warnings.

The diagnostics for model are displayed in the Diagnostic Viewer user interface. To know more about the diagnostic viewer, see the topic View Diagnostics.

You can also add Model Verification blocks to your model, to check the condition of specific signals. To know more about Model Verification, see topics listed under Run Model Checks.
