Have there been any file name changes in the Stratix® V transceiver Megawizard files in Quartus® II 12.1?

Description

Yes, naming changes have been made to the underlying transceiver Megawizard files in Quartus® II 12.1.

Previous to Quartus® II 12.1, an example name might be:

In Quartus® II 12.1, this would change to:
