1. On the Project menu, click Add/Remove Files in Project. The Settings dialog box
appears.
2. In the Category list, select Files.
3. Click Browse (...)
after File name and from the project folder, select
ALTPLL_RECONFIG_rom.v
. This file is the top-level module that contains the

pll_reconfig_circuit
and
the_pll
instances.
4. To add the top-level file to the project, click Add.
5. Click OK.

The top-level file is added to the project.
7. To compile the design, on the Processing menu, click Start Compilation.
8. When the Full Compilation was successful
