Depending on the board selected, provide XDC constraints for the system clock pins and SelectIO pins of AXI Chip2Chip core. The status signals (Link Status, Multi-Bit Error, and Link Error) can be mapped to LEDs to show the status of the AXI Chip2Chip cores.
See the AXI Chip2Chip Reference Design for Real-Time Video Application (XAPP1160) [Ref 1] to set the SelectIO pin constraints for AXI Chip2Chip core on KC705 board.
