Real-Time Windows Target

Creating a Real-Time Application

Real-Time Workshop generates C code from your Simulink model, then a third-party C compiler compiles and links that C code into a real-time application.

After you enter parameters into the Simulation Parameters dialog box for Real-Time Workshop, you can build a real-time application. This procedure uses the Simulink model rtwin_model.mdl as an example, and assumes you have loaded that model:

1. In the Simulink window, and from the Tools menu, point to Real-Time Workshop, and then click Build Model.

1. The build process does the following:
   • Real-Time Workshop creates the C code source files rtwin_model.c and rtwin_model.h.
   • The make utility make_rtw.execreates the makefile rtwin_model.mk from the template makefile rtwintmf.
   • The make utility make_rtw.exe builds the real-time application rtwin_model.rwd using the makefile rtwin_model.mk created above. The file rtwin_model.rwd is a binary file that we refer to as your real-time application. You can run the real-time application with the Real-Time Windows Target kernel.

2. Connect your Simulink model to your real-time application. See Entering Additional Scope Parameters for Signal Tracing.

After you create a real-time application, you can exit MATLAB, start MATLAB again, and then connect and run the executable without having to rebuild.
