Enforce sample times specified by Signal Specification blocks

Description

Select the diagnostic action to take if the sample time of the source port of a signal specified by a Signal Specification block differs from the signal's destination port.

Category: Diagnostics

Settings

Default: warning

none: Simulink^® software takes no action.
warning: Simulink software displays a warning.
error: Simulink software terminates the simulation and displays an error message.

Note

The setting of this diagnostic is ignored when the Default parameter behavior parameter in the Code Generation > Optimization pane of the model Configuration Parameters is set to Tunable.

Tips

The Signal Specification block allows you to specify the attributes of the signal connected to its input and output ports. If the specified attributes conflict with the attributes specified by the blocks connected to its ports, Simulink software displays an error when it compiles the model, for example, at the beginning of a simulation. If no conflict exists, Simulink software eliminates the Signal Specification block from the compiled model.
You can use the Signal Specification block to ensure that the actual attributes of a signal meet desired attributes, or to ensure correct propagation of signal attributes throughout a model.
