Simulation range checking

Diagnostic action to take when signal value is outside its specified value range

Model Configuration Pane: Diagnostics / Data Validity

Description

The Simulation range checking parameter specifies the diagnostic action to take when a signal value is less than its specified minimum value or greater than its specified maximum value. For information about specifying value ranges for signals and how the software checks signals that have a data type other than double, see Specify Signal Ranges.

The software performs signal range checking only for root-level input and output signals of model references that simulate in accelerator mode.

If you have an Embedded Coder^® license, you can perform signal range checking in top-model or Model block software-in-the-loop (SIL) and processor-in-the-loop (PIL) simulations. For more information, see Choose a SIL or PIL Approach (Embedded Coder).

Settings

none (default) | warning | error

none: The software does not issue a diagnostic if a signal value is outside its specified range.
warning: The software issues a warning if a signal value is outside its specified range.
error: The software issues an error and terminates the simulation if a signal value is outside its specified range.
