ID:15206 coreclk input port of GXB receiver channel atom "<name>" is unconnected, but must be fed by either clock2 output port of a GXB transmitter PLL or clkout output port of GXB receiver channel atom "<name>"

CAUSE: The coreclk input port of the specified gigabit transceiver block (GXB) receiver channel atom is unconnected. However, the coreclk input port of the GXB receiver channel atom must be fed by the clock2 output port of a GXB transmitter PLL or the clkout output port of the specified GXB receiver channel atom.

ACTION: Connect the coreclk input port of the GXB receiver channel atom to either the clock2 output port of a GXB transmitter PLL or to the clkout output port of the same GXB receiver channel atom.
