Installing and Licensing IP Cores
The Altera IP Library provides many useful IP core functions for production use without purchasing an
additional license. You can evaluate any Altera ® IP core in simulation and compilation in the Quartus ® II
software using the OpenCore ® evaluation feature. Some Altera IP cores, such as MegaCore ® functions,
require that you purchase a separate license for production use. You can use the OpenCore Plus feature to
evaluate IP that requires purchase of an additional license until you are satisfied with the functionality and
performance. After you purchase a license, visit the Self Service Licensing Center to obtain a license
number for any Altera product.

IP Catalog and Parameter Editor
The Quartus II IP Catalog (Tools > IP Catalog) and parameter editor help you easily customize and
integrate IP cores into your project. You can use the IP Catalog and parameter editor to select, customize,
and generate files representing your custom IP variation.
Note: The IP Catalog (Tools > IP Catalog) and parameter editor replace the MegaWizard
™ Plug-In
Manager for IP selection and parameterization, beginning in Quartus II software version 14.0. Use
the IP Catalog and parameter editor to locate and paramaterize Altera IP cores.
The IP Catalog lists IP cores available for your design. Double-click any IP core to launch the parameter
editor and generate files representing your IP variation. The parameter editor prompts you to specify an
IP variation name, optional ports, and output file generation options. The parameter editor generates a
top-level Qsys system file ( .qsys ) or Quartus II IP file ( .qip ) representing the IP core in your project. You
can also parameterize an IP variation without an open project.
