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 Speedgoat^® 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.

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.
