Saturate on overflow

Description

Select the diagnostic action to take if the value of a signal is too large to be represented by the signal data type, resulting in a saturation.

Category: Diagnostics

Settings

Default: warning

none

Simulink® software takes no action.

warning

Simulink software displays a warning.

error

Simulink software terminates the simulation or code generation and displays an error message.

Tips

  • This diagnostic applies only to overflows which saturate for integer and fixed-point data types.

  • To check for floating-point overflows (for example, Inf or NaN) for double or single data types, select the Inf or NaN block output diagnostic. (See Inf or NaN block output for more information.)

  • During code generation, Simulink may simulate a few blocks in the model for optimization purposes. If simulation of these blocks triggers this diagnostic to report an error, the software terminates code generation.
