Detect underflow
Specifies diagnostic action to take when a fixed-point constant underflow occurs during simulation.
Description
Select the diagnostic action to take if Simulink®software detects a 32-bit integer value was converted to a floating-point value.
Category:Diagnostics
Settings
Default:none
-
none
-
Simulink software takes no action.
-
warning
-
Simulink software displays a warning.
-
error
-
Simulink software terminates the simulation and displays an error message.
Tips
This diagnostic applies only to fixed-point constants (net slope and net bias).
Fixed-point constant underflow occurs when Simulink software encounters a fixed-point constant whose data type does not have enough precision to represent the ideal value of the constant because the ideal value is too small.
When fixed-point constant underflow occurs, casting the ideal value to the data type causes the value of the fixed-point constant to become zero, and therefore to differ from its ideal value.
Dependency
This parameter requires a Fixed-Point Designer™ license.
