Notes:

1. The values in this table reflect the default device (xc7vx485tffg1157-1). Default values for UltraScale architecture devices are denoted with a slash (/) where appropriate.

2. X0Y0 GT selection is based upon columns.

3. If a device has transceivers on both sides, left is the default value.

4. If a 7 series device has GTX transceivers, gtx is the default value. If GTH transceivers, v7gth is the default value.

5. Numbering for the default device starts from GTXE2_CHANNEL_X1Y4. Otherwise, numbering starts from GTXE2_CHANNEL_X0Y0.

6. C_GT_LOC_i where i varies from 1 to 48.

7. By default, the lowest i C_GT_LOC_i is assigned.

8. If Shared Logic in Core option is selected, SupportLevel is 1.

9. Not available in UltraScale devices.

10. The Lanes and GT Type options for UltraScale devices are available on the Core Options page in the Vivado IDE.

11. Not available in 7 series devices.

12. Available if Include Shared Logic in core option is selected.

13. The GT Refclk selection option is not applicable for line rate > 16.375G core configuration. Defaulted to GTREFCLK0 of each active transceiver Quads reference clocks.

14. Generate Aurora without GT option is available only for UltraScale and UltraScale+ devices in IP catalog.

15. Fractional divider option is not supported in GTY based designs.
