Edit all IP cores with the IP Catalog and parameter editor. The IP Catalog and parameter editor replace the MegaWizard Plug-In Manager in the Quartus II software to unify all Altera IP within one GUI. The Quartus II software might generate messages that refer to the MegaWizard Plug-In Manager. Substitute "IP Catalog and parameter editor" for "MegaWizard Plug-In Manager" in these messages. The following links provide additional details and training on the new IP Catalog tool.
