POS-PHY Level 4 MegaCore Function IP Toolbench has an Error After Changing the Device Family

If you change the device family when editing an existing custom megafunction variation (POS-PHY Level 4 MegaCore function variation) without first changing the device family in the Quartus II project, an error may occur when generating the MegaCore function. This results in a MegaCore function generation error message.This issue also applies when creating a new custom megafunction variation, if you use a different device family to that specified in the Quartus II project.

Before using the MegaWizard Plug-In Manager to create or edit a POS-PHY Level 4 custom megafunction variation, make sure that a Quartus II project exists and that the required device family is set in the project. To set the device family, in the Quartus II software, on the Assignments menu click Device.

When using the MegaWizard Plug-In Manager to create or edit the megafunction variation, set the device family to be the same as the device family set in the Quartus II project. You can set the device family in the Basic Parameters tab when parameterizing the MegaCore function.
