MegaCore^® megafunctions are pre-verified HDL design files for complex system-level functions. These pre-tested megafunctions are optimized for all Altera^® device architectures and can be purchased from Altera. Altera MegaCore megafunctions consist of several different design files. A post-synthesis AHDL design file is used for design implementation (that is fitting) in the target Altera device. In addition, VHDL or Verilog HDL functional simulation models are supplied for design and debugging with standard EDA simulation tools.

MegaCore/OpenCore^® megafunctions are available from the Altera web site at http://www.altera.com or from the IP MegaStore^™ in the MegaWizard^® Portal extension to the MegaWizard Plug-in Manager (Tools menu).

If your license file support for a MegaCore megafunction includes permission to view the source design file, you can view the file by selecting the megafunction symbol in the Block Editor or megafunction name in the Text Editor and choosing Open Parent Entity (Project Menu).
