CAUSE: The specified input port of the specified gigabit transceiver block (GXB) receiver channel atom is unconnected due to the specified reason. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager .

ACTION: Disconnect the input port. To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager to specify legal input port connections.
