Using Simulink

How to Run the Simulink Accelerator

To activate the Simulink Accelerator, select Accelerator under the Simulation menu for your model. This picture shows the procedure using the F14 flight control model.

Alternatively, you can select Accelerator from the menu located on the right-hand side of the toolbar.

To begin the simulation, select Start from the Simulation menu. When you start the simulation, the Accelerator generates the C code and compiles it. The Accelerator then does the following:

• Places the generated code in a subdirectory called modelname_accel_rtw (in this case, f14_accel_rtw)
• Places a compiled MEX-file in the current working directory
• Runs the compiled model

Note    If your code does not compile, the most likely reason is that you have not set up the mex command correctly. Run mex -setup at the MATLAB prompt and select your C compiler from the list shown during the setup.

The Accelerator uses Real-Time Workshop technology to generate the code used to accelerate the model. However, the generated code is suitable only for acceleration of the model. If you want to generate code for other purposes, you must use the Real-Time Workshop.
