Creating the Amplitude Modulation Model
f For information about controlling the DSP Builder design flow using Signal
Compiler , refer to “Design Flows for Synthesis, Compilation and Simulation” on
page 3–19 .
f For more information about the blocks in the DSP Builder blockset, refer to the DSP
Builder Standard Blockset Libraries section in volume 2 of the DSP Builder Handbook .
Creating the Amplitude Modulation Model
This tutorial uses an amplitude modulation design example, singen.mdl , to
demonstrate the DSP Builder design flow.
The amplitude modulation design example is a modulator that has a sine wave
generator, a quadrature multiplier, and a delay element. Each block in the model is
parameterizable. When you double-click a block in the model, a dialog box displays
where you can enter the parameters for the block. Click the Help button in these
dialog boxes to view help for a specific block.
This tutorial assumes the following points:
You are using a PC running Windows XP.
You are familiar with the MATLAB, Simulink, Quartus II, and ModelSim ?
software and the software is installed on your PC in the default locations.
You have basic knowledge of the Simulink software.
f For information about using the Simulink software, refer to the Simulink
Help.
You can use the singen.mdl model file in < DSP Builder install
path >\DesignExamples\Tutorials\GettingStartedSinMdl or you can create your
own amplitude modulation model.
To create the amplitude modulation model, follow these instructions.
Create a New Model
To create a new model, follow these steps:
1. Start the MATLAB software.
2. On the File menu, point to New, and click Model to create a new model window.
3. In the new model window, on the File menu click Save .
4. Browse to a directory, your working directory, to save the file. This tutorial uses
the working directory < DSP Builder install
path >\DesignExamples\Tutorials\GettingStartedSinMdl\my_SinMdl .
5. Type the file name into the File name box. This tutorial uses the name singen.mdl .
6. Click Save .
7. Click the MATLAB Start button. Point to Simulink and click Library Browser .
