Simulink Real-Time

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

Since R2020b

Description

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

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

Use the actions in the Connect to Target Computer section to select and connect to a target computer.

	Launch external mode control panel. The control panel opens.
	Link sets of signals from files and workspace to root Inport blocks. The Root Inport Mapper opens.
	Communicate changes of multiple parameters at once. For more information, see Tune Parameters by Using Hold Updates and Update All Parameters.
	Update all parameters on target computer. For more information, see Tune Parameters by Using Hold Updates and Update All Parameters.
	Remove hardware configuration from this model. The code generation target is set to grt.tlc.

Use the actions in the Run on Target section build the model, deploy the real-time application to the target computer, and run the real-time application.

UI Control	Description
	Run application on target computer, observe outputs, and tun parameters. One-click builds and deploys real-time application when model changes are found. For more information, see Build and Download Real-Time Application by Using Run on Target.
	Generate a real-time application from Simulink mode. For more information, see Execute Real-Time Application in Simulink External Mode by Using Step-by-Step Commands.
	Deploy real-time application to target computer. For more information, see Execute Real-Time Application in Simulink External Mode by Using Step-by-Step Commands.
	Connect Simulink model to real-time application on target computer. For more information, see Execute Real-Time Application in Simulink External Mode by Using Step-by-Step Commands.
	Run real-time application. Observe output and tune parameters by using Simulink model. For more information, see Execute Real-Time Application in Simulink External Mode by Using Step-by-Step Commands.
	Restart real-time application on target computer. For more information, see Execute Real-Time Application in Simulink External Mode by Using Step-by-Step Commands.
	Stop real-time application on target computer. For more information, see Execute Real-Time Application in Simulink External Mode by Using Step-by-Step Commands.
	Disconnect Simulink model from real-time application on target computer. For more information, see Execute Real-Time Application in Simulink External Mode by Using Step-by-Step Commands.
	Import the file log data on application stop. For more information, see the AutoImportFileLog argument for the start function or stop function. You also can select this option by using the Run or Stop button in Simulink Real-Time Explorer.

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.
	Start signal logging and streaming. For more information, see startRecording function and Signal Logging and Streaming Basics.
	Stop signal logging and streaming. For more information, see stopRecording function and Signal Logging and Streaming Basics.
	Visualize, measure, and analyze transitions and states over time in the Logic Analyzer.
	View real-time application task execution time. For more information, see Simulink Real-Time TET Monitor.
	Launch App Generator to create an App Designer instrument panel. For more information, see Simulink Real-Time App Generator.
	Use the Simulink model to select signals to view in the Simulation Data Inspector. After adding and instrument to the model, the button label changes from Add Instrument to Configure Instrument. For more information, see Add Instruments to Real-Time Application from Simulink Model.

Version History

Introduced in R2020b

R2023a: UI enhancements for file log import options

In the Simulink Editor, on the Real-Time tab, you can enable the AutoImportFileLog check box from the Run on Target button, Start Application button, or Stop Application button. This check box corresponds to the AutoImportFileLog option of the start function and stop function.

R2022a: Added App Generator

The Simulink Real-Time App Generator creates App Designer instrument panels from the Simulink model or from generated application (MLDATX) files.

R2022a: AutoImportFileLog Available from Run on Target

The AutoImportFileLog check box is available from the Run on Target button on the Real-Time tab in the Simulink Editor. This checkbox corresponds to the AutoImportFileLog option of the start function.

R2021b: Bind mode for signals to instruments in Simulink Editor

You can bind signals to instruments (also referred to as instrumenting a signal) by using the Add Instrument button to enter bind mode in the Simulink Editor. You can select signals in the model and stream signal data for those signals from the real-time application to the Simulation Data Inspector.

R2021b: Changed Batch Mode Button Label to Hold Updates

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