Design Flows
DSP Builder Flow
© December 2010 Altera Corporation
The FFT MegaCore function supports the following design flows:
■
■
This chapter describes how you can use a FFT MegaCore function in either of these
flows. The parameterization provides the same options in each flow and is described
in
After parameterizing and simulating a design in either of these flows, you can
compile the completed design in the Quartus II software.
Altera’s DSP Builder product shortens digital signal processing (DSP) design cycles
by helping you create the hardware representation of a DSP design in an
algorithm-friendly development environment.
DSP Builder integrates the algorithm development, simulation, and verification
capabilities of The MathWorks MATLAB
with Altera Quartus
can combine existing Simulink blocks with Altera DSP Builder blocks and MegaCore
function variation blocks to verify system level specifications and perform simulation.
In DSP Builder, a Simulink symbol for the MegaCore function appears in the
MegaCore Functions library of the Altera DSP Builder Blockset in the Simulink library
browser.
You can use the FFT MegaCore function in the MATLAB/Simulink environment by
performing the following steps:
1. Create a new Simulink model.
2. Select the fft_<version> block from the MegaCore Functions library in the
3. Double-click on the fft_<version> block in your model to display the
4. Click Finish in the MegaWizard interface to complete the parameterization and
5. Connect your FFT MegaCore function variation to the other blocks in your model.

DSP Builder: Use this flow if you want to create a DSP Builder model that
includes a FFT MegaCore function variation.
MegaWizard™ Plug-In Manager: Use this flow if you would like to create a FFT
MegaCore function variation that you can instantiate manually in your design.
Simulink Library Browser, add it to your model, and give the block a unique
name.
MegaWizard interface and parameterize the MegaCore function variation. For an
example of setting parameters for the FFT MegaCore function, refer to
