I have a program which uses several transceivers on a FMC and the ethernet port of my VC707, everything works quite well. Since I tried to add an Aurora64b66b Core to have a transceiver connection over SMA to another VC707, the implementation fails with following message:
When I have a look on the design, it seems that the mac_engine may collide with the Aurora Core (Region X1Y0, right end):
Does anyone know how to solve this problem? Do I have to manually place components to the same clock region and if yes how can I do this?
I appreciate your help, thank you so much

Can you please share post opt dcp file which will be located in <project>/<project>.runs/impl_1/**_opt.dcp

In the shared post opt dcp, I see that you have two GT_CHANNEL instances "sip_vc707_mac_engine_sgmii_0/mac_engine_inst/core_wrapper/U0/transceiver_inst/gtwizard_inst/U0/gtwizard_i/gt0_GTWIZARD_i/gtxe2_i" & "design_uplink_i/aurora_64b66b_0/inst/design_uplink_aurora_64b66b_0_0_core_i/design_uplink_aurora_64b66b_0_0_wrapper_i/design_uplink_aurora_64b66b_0_0_multi_gt_i/design_uplink_aurora_64b66b_0_0_gtx_inst/gtxe2_i" locked in single clock region (X0Y1) are connected to two different GT_COMMON instance which is causing the error.
1. GT_COMMON and the GT_CHANNEL should always be placed in the same clock region.
2. A clock region has only one GT_COMMON site
You need to revisit your code and do the modifications to overcome this error.

Did the suggestion from my previous post provided any help?
