ID:21089 "<name>" must be driven by the same source. Connections across partition boundaries need to be sourced by the same port to guarantee that the source remains the same over subsequent incremental compilations.

CAUSE: The sources of the ports must be the same. If this port is driven from another partition, the Quartus Prime software cannot guarantee that the sources will be the same for future incremental compilations.

ACTION: Restructure your HDL or partition assignments such that the source and the gigabit transceiver block (GXB) are in the same partition.
