Phase-Locked Loop Reconfiguration (ALTPLL_RECONFIG) Megafunction
February 2012
Altera Corporation
The ALTPLL megafunction allows you to generate additional configuration files
without going through a compilation stage. It allows you to generate as many
unique configuration files as you need without the difficulty of multiple
compilation flows. All you need to do is to set the intended PLL settings, enter the
file name, and click Generate A Configuration File. Use this capability with the
PLL reconfiguration of multiple .mif files via external ROMs in the
ALTPLL_RECONFIG megafunction.
7. Click Finish. The the_pll.v module is built.
8. Click OK. The MegaWizard Plug-In Manager resets to page 2a so you can create a
new custom function variation.
9. In the MegaWizard Plug-In Manager pages, select or verify the configuration
settings listed in
. Click Next to advance from one page to the next.
10. Click Finish. The
pll_reconfig_circuit
module is built.

Select Yes, use this file for the content data
File name

Ensure that this option shows the correct path of the .mif
file before compiling the design to avoid scan chain
mismatch warnings.
Do not use pre initialized RAM - initialize
from ROM instead
