Signal Properties Controls

Signal name

Name of signal.

To name a signal programmatically, see Name a Signal Programmatically.

Signal name must resolve to Simulink signal object

Specifies that either the base MATLAB® workspace, the model workspace, or the data dictionary must contain a Simulink.Signal object with the same name as this signal. Simulink® software displays an error message if it cannot find such an object when you update or simulate the model containing this signal.

    Note:   Simulink.Signal objects in the model workspace must have their storage class set to Auto. See Model Workspaces for more information.

When Signal name must resolve to Simulink signal object is enabled, a signal resolution icon appears by default to the left of any label on the signal. The icon looks like this:

See Signal to Object Resolution Indicator for more information.

This property appears only if you set the model configuration parameter Signal resolution to a value other than None.

To set this option programmatically, use the port parameter MustResolveToSignalObject. See Use Signal Objects.

Show propagated signals

Enabling this property causes Simulink to create a propagated signal label.

For example, in the following model, the output signal from the Subsystem block is configured for signal label propagation. The propagated signal label (<const>) is based on the name of the upstream output signal of the Constant block (const).

For more information, see Signal Label Propagation.

To set this option programmatically, use the port parameter SignalPropagation. See Display Propagated Signal Labels.
