Set Up Licensing
You need to purchase a license for the MegaCore function only when you are
completely satisfied with its functionality and performance, and want to take your
design to production.

If you replace the DDR or DDR2 SDRAM controller MegaCore function control logic
with your own logic, you need not purchase a license and can continue to use the
clear-text datapath logic.
After you purchase a license for DDR or DDR2 SDRAM controller MegaCore
function, you can request a license file from the Altera web site at
www.altera.com/licensing and install it on your computer. When you request a
license file, Altera emails you a license.dat file. If you do not have Internet access,
contact your local Altera representative.
