9. The remaining pages in the New Project Wizard are optional. Click Finish to
complete the Quartus II project.
You have finished creating your new Quartus II project.
Launch MegaWizard Plug-in Manager
To launch the MegaWizard Plug-in Manager in the Quartus II software, follow these
steps:
1. Start the MegaWizard ? Plug-In Manager by choosing the MegaWizard Plug-In
Manager command (Tools menu). The MegaWizard Plug-In Manager dialog box
displays.
f Refer to the Quartus II Help for more information on how to use the
MegaWizard Plug-In Manager.
2. Specify that you want to create a new custom megafunction variation and click
Next .
3. Expand the Communications > Encoding/Decoding directory, then click 8B10B
Encoder-Decoder v9.1.
4. Choose the device family you want to use for this MegaCore function, for example
Stratix II GX .
5. Select the output file type for your design; the MegaWizard interface supports
VHDL and Verilog HDL.
6. The MegaWizard Plug-In Manager shows the project path that you specified in the
New Project Wizard . Append a variation name for the MegaCore function output
files < project path >\< variation name >.
7. Click Next to display the Parameter Settings page for the 8B10B Encoder/Decoder
MegaCore Function.

You can change the page that the MegaWizard Plug-In Manager displays by
clicking Next or Back at the bottom of the dialog box. You can move
directly to a named page by clicking the Parameter Settings , EDA , or
Summary tab.
Parameterize
To parameterize your MegaCore function, perform the following steps:
1. Select the mode of operation, either Encoder or Decoder .
2. If you selected Encoder , turn on the Register inputs/outputs check box for a three-
cycle latency, or turn off the Register inputs/outputs check box for a single-cycle
latency.

The Decoder always has registered inputs and outputs.
3. Click Next (or the EDA tab) to display the simulation setup page .
