Due to a mismatch between the ZCU102/ZCU106 FMC-HPC0 and the GT Bank, the GT channel must be swapped accordingly during the post optimize design of implementation stage, by overwriting the constraint for the ZCU102/ZCU106.
Table 1. ZCU102/ZCU106 GT Lane Swap Mapping
GT Channel GT LOC
0 GTHE4_CHANNEL_X0Y14
1 GTHE4_CHANNEL_X0Y13
2 GTHE4_CHANNEL_X0Y15
3 GTHE4_CHANNEL_X0Y12
  1. Use the following code to replace the constraint for the ZCU102/ZCU106:
    # Reset the LOC property to remove the previous LOC
    reset_property LOC [get_cells -hierarchical -filter {NAME =~ *gen_channel_container[3].*gen_gthe4_channel_inst[0].GTHE4_CHANNEL_PRIM_INST}]
    reset_property LOC [get_cells -hierarchical -filter {NAME =~ *gen_channel_container[3].*gen_gthe4_channel_inst[1].GTHE4_CHANNEL_PRIM_INST}]
    reset_property LOC [get_cells -hierarchical -filter {NAME =~ *gen_channel_container[3].*gen_gthe4_channel_inst[2].GTHE4_CHANNEL_PRIM_INST}]
    reset_property LOC [get_cells -hierarchical -filter {NAME =~ *gen_channel_container[3].*gen_gthe4_channel_inst[3].GTHE4_CHANNEL_PRIM_INST}]
    
    # Assign new LOC property according to ZCU106 HPC0 wiring
    set_property LOC GTHE4_CHANNEL_X0Y14 [get_cells -hierarchical -filter {NAME =~ *gen_channel_container[3].*gen_gthe4_channel_inst[0].GTHE4_CHANNEL_PRIM_INST}]
    set_property LOC GTHE4_CHANNEL_X0Y13 [get_cells -hierarchical -filter {NAME =~ *gen_channel_container[3].*gen_gthe4_channel_inst[1].GTHE4_CHANNEL_PRIM_INST}]
    set_property LOC GTHE4_CHANNEL_X0Y15 [get_cells -hierarchical -filter {NAME =~ *gen_channel_container[3].*gen_gthe4_channel_inst[2].GTHE4_CHANNEL_PRIM_INST}]
    set_property LOC GTHE4_CHANNEL_X0Y12 [get_cells -hierarchical -filter {NAME =~ *gen_channel_container[3].*gen_gthe4_channel_inst[3].GTHE4_CHANNEL_PRIM_INST}]
