See the diagram in the information area in This Figure . Each numbered row represents a serial transceiver tile and each active box represents an available GTX or GTH transceiver. For each Aurora 64B/66B lane in the core, starting with Lane 1, select a GTX or GTH transceiver and place the lane by selecting its number in the GTX or GTH transceiver placement box.
• X in the drop-down menu means that lane is not selected.
• <1—16> selected from the drop-down menu means that particular lane is selected. It does not assign that number to the physical lane.
RECOMMENDED: Always select consecutive/physically adjacent lanes for a multi-GT design.
Note: The core generates transceiver placement (LOC) constraints in ascending fashion. Move the cursor in the Vivado IDE to see the transceiver being selected in the 7 series and Zynq®-7000 family-based design. Lane numbering serves only to enable the lanes and not to assign numbers to the lanes. The Lane Assignment is not available for UltraScale architecture-based designs. It is strongly recommended that lane selection should be continuous for timing closure.
