Detect downcast

Diagnostic action to take when parameter downcast occurs during code generation

Model Configuration Pane: Diagnostics / Data Validity

Description

The Detect downcast parameter specifies the diagnostic action to take when a parameter downcast occurs during code generation. A parameter downcast occurs if the computation of the block output requires converting the parameter data type to a data type that has a smaller range of values. For example, converting the data type of a parameter from uint32 to uint8 is a parameter downcast.

This diagnostic applies only to named tunable parameters that have a non-Auto storage class.

Settings

error (default) | warning | none

error: The software issues an error and terminates code generation if a parameter downcast occurs.
warning: The software issues a warning if a parameter downcast occurs during code generation.
none: The software does not issue a diagnostic if a parameter downcast occurs during code generation.
