Description
You will get this error message when trying to generate IBIS models in the Quartus® II software when you have an un-licensed OpenCore Megafunction in your design.
To get around this, you can remove the un-licensed OpenCore Megafunction from your design and generate the IBIS models. Or you can fully license the OpenCore Megafunction.
This is scheduled to be fixed in a future version of the Quartus II software.
