ID:15134 You specified location assignments for transceiver Avalon Memory-Mapped interface group"<text>". If the Fitter reports placement errors for the merged transceiver Avalon Memory-Mapped interface, check whether the two locations map to the same physical transceiver channel.

CAUSE: The TX Channel and RX Channel (or CDR PLL) may map to two different transceiver channel locations. After merging transceiver Avalon Memory-Mapped interface group assignments for the same group name, the TX channel and RX Channel (or CDR PLL) will map to the same channel location.

ACTION: Change the TX Channel or CDR PLL assignment to match the same channel location or remove one of the assignment. You can change location assignments in the Assignment Editor.
