Data Validity Diagnostics Overview

Specify what diagnostic action Simulink® software should take, if any, when it detects a condition that could compromise the integrity of data defined by the model, as well as the Data Validity parameters that pertain to code generation, and are used to debug a model.


Set the parameters displayed.


  • To open the Data Validity pane, in the Simulink Editor, in the Modeling tab, click Model Settings, then select Diagnostics > Data Validity.

  • The options are typically to do nothing or to display a warning or an error message.

  • A warning does not terminate a simulation, but an error does.

To get help on an option

  1. Right-click the option text label.

  2. From the context menu, select What's This.
