User Guide
4. In the New Project Wizard: Directory, Name, Top-Level Entity page, enter the
following information:
a. Specify the working directory for your project. For example, this walkthrough
uses the c:\altera\projects\sdi_project directory.
1 The Quartus II software automatically specifies a top-level design entity
that has the same name as the project. This walkthrough assumes that the
names are the same.
b. Specify the name of the project. This walkthrough uses project for the project
name.
5. Click Next to close this page and display the New Project Wizard: Add Files page.
1 When you specify a directory that does not already exist, a message
prompts you to create a specified directory. Click Yes to create the directory.
6. If you installed the MegaCore IP Library in a different directory from where you
installed the Quartus II software, you must add the user libraries:
a. Click User Libraries.
b. Type <path>
\ip
into the Library name field, where <path> is the directory in
which you installed the SDI.
c. Click Add to add the path to the Quartus II project.
d. Click OK to save the library path in the project.
7. Click Next to close this page and display the New Project Wizard: Family &
Device Settings page.
8. On the New Project Wizard: Family & Device Settings page, choose the target
device family in the Family list.
9. The remaining pages in the New Project Wizard are optional. Click Finish to
complete the Quartus II project.
Launching MegaWizard Plug-In Manager
To launch the MegaWizard Plug-In Manager in the Quartus II software, follow these
steps:
1. On the Tools menu, click MegaWizard Plug-In Manager.
1 For more information about how to use the MegaWizard Plug-In Manager,
refer to Quartus II Help.
2. Specify that you want to create a new custom megafunction variation and click
Next.
3. Expand the Interfaces > SDI folder and click SDI <version>.
4. Select the output file type for your design; the wizard supports VHDL and Verilog
HDL.
