Displaying Block Outputs

Block Output Data Tips

For many blocks, Simulink can display block output (port values) as data tips on the block diagram while a simulation is running. The following model shows a port value data tip for the Fcn block.

Note   The block output display feature has limitations for models with: Accelerated modes Signal storage reuse Signals with some complex data types, such as bus signals See Port Value Display Limitations.

Setting Block Output Data Tip Options

You can set data tip options by selecting Port Values > Options from the Model Editor View menu and using the Block Output Display Options dialog.

Enabling Block Output Display

To turn block output display on or off, select one these options:

• Show None

  Turns off block output display.

• Show When Hovering

  Displays output port values for the block under the mouse cursor.

• Toggle When Clicked

  Displays output port values when you select a block. Reselecting that block turns off the display.

The Microsoft Windows operating system Simulink version also has a Model Editor output display button to control block output display when hovering.

Controlling the Block Output Display

You can specify how the block output display is formatted and how frequently the display updates.

Port Value Display Limitations

Accelerated Modes

Port values do not update in a model that simulates in any accelerated mode. The limitation exists whether the model itself specifies accelerated simulation or the model is subordinate to a model that specifies accelerated simulation. See Accelerating Models, Accelerator Mode, and Testing and Refining Concept Models With Standalone Rapid Simulations for more information.

Signal Storage Reuse

A model with Signal storage reuse enabled displays a warning when you set Display values to Show When Hovering or Toggle When Clicked .

Click the OK button if you want the new Display values option to take effect, despite the possibility that values for output ports could be incorrect.

Signal Data Types

The port value displays for ports connected to most kinds of signals, including signals with built-in data types (such as double, int32, or Boolean), DYNAMICALLY_TYPED, and several other data types. However, no data displays for signals with some complex data types, such as bus signals.
