Array bounds exceeded

Diagnostic behavior when S-function writes beyond array bounds assigned in allocated memory

Model Configuration Pane: Diagnostics / Data Validity

Description

This parameter specifies the diagnostic behavior in the software when an S-function writes to memory locations not allocated for the block. Writing outputs, states, or work vectors outside of the memory allocated for the block indicates a bug in the S-function. For more information, see Handle Errors in S-Functions.

Setting this parameter to a value other than none degrades simulation performance. Set the parameter value to warning or error only to debug an S-function in your model.

The software ignores this parameter for referenced models that simulate in accelerator mode. You can use the Model Advisor to check for diagnostic parameters that are ignored for referenced models that simulate in accelerator mode.

Settings

none (default) | warning | error

Default: none

none

The software does not issue a diagnostic.

warning

The software issues a warning.

error

The software issues an error and terminates the simulation.
