Simulink Desktop Real-Time

Generate real-time applications for simulations that run on a desktop computer and interface with I/O devices in the computer

Since R2019b

Description

Use the Simulink Desktop Real-Time app to configure a model to build and run real-time applications on a desktop computer. The app configures the model to use the Simulink Desktop Real-Time code generation target and other configuration parameters for code generation. When you open the app, a Desktop Real-Time tab is added to the toolstrip. The Desktop Real-Time tab represents groups of tasks in the Simulink Desktop Real-Time workflow.

After you use the app to configure the model for Simulink Desktop Real-Time, you can perform these and more tasks from the Desktop Real-Time tab in the Simulink Editor.

Use the actions in the Mode section to select the simulation mode.

UI Control	Description
	Compile model into real-time application and run the application on desktop computer in real time. Monitor signals and tune parameters (external mode). For more information, see Real-Time Execution in Run in Kernel Mode.
	Communicate with hardware inputs and outputs in real-time (normal mode). For more information, see Real-Time Execution in Connected IO Mode.

Use the actions in the Prepare section to configure the model and tune parameters.

UI Control	Description
	Configure model to run on hardware. The Configuration Parameters dialog box opens.
	Send signal to the Simulation Data Inspector and workspace. Select one or more signals before using this button.
	Add a viewer to the selected signals. Select one or more signals before using this button.
	Allocate memory and make signals observable when using a Floating Scope. Select one or more signals before using this button.
	Show table to manage signal logging and viewing. The Signal Table tab opens at the bottom of the Simulink Editor.
	Configure logging. The Data Inport/Export tab of the Configuration Parameters dialog box opens.
	Launch external mode control panel. The control panel opens.
	If this button is toggled on, you can defer the update of block parameters until you click Update All Parameters or toggle off this button. For more information, see Tune Parameters by Using Hold Updates and Update All Parameters.
	Update all parameters on hardware. For more information, see Tune Parameters by Using Hold Updates and Update All Parameters.
Remove Hardware Configuration Remove hardware configuration from this model	Remove hardware configuration from this model. The code generation target is set to grt.tlc.

Use the actions in the Run in Real Time section build the model and run the real-time application.

UI Control	Description
	Compile model into real-time application and run the application on the desktop computer in real time. Monitor signals and tune parameters. For more information, see Execute Real-Time Application in Run in Kernel Mode by Using Run in Real Time.
	Generate executable application. For more information, see Execute Real-Time Application in Run in Kernel Mode by Using Step by Step Commands.
	Connect model to application on hardware. For more information, see Execute Real-Time Application in Run in Kernel Mode by Using Step by Step Commands.
	Start monitoring signals and tuning parameters. For more information, see Execute Real-Time Application in Run in Kernel Mode by Using Step by Step Commands.
	Stop application on hardware an disconnect model. For more information, see Execute Real-Time Application in Run in Kernel Mode by Using Step by Step Commands.

Use the actions in the Review Results section instrument the model and observe outputs.

UI Control	Description
	View logged data in the Simulation Data Inspector.
	Visualize, measure, and analyze transitions and states over time in the Logic Analyzer.

Version History

Introduced in R2019b

R2021b: Select Run in Kernel Mode or Connected IO Mode for Real-Time Simulation

To select the real-time simulation mode, use the Run in Kernel mode or Connected IO mode buttons on the Simulink editor Desktop Real-Time tab. These selections are a change from using a combination of control on the Simulation tab and the Desktop Real-Time tab. With this change, the simulation mode selections on the Simulation tab no longer affect real-time normal mode or real-time external mode simulation.

R2021b: Label Change for Batch Mode Button

On the Desktop Real-Time tab, The label for the Batch Mode button changed to Hold Updates.
