Two Aurora Instances in same Quad via Block Design

Jump to solution

I have created a block design with two Aurora block.  They share the same time but are independent.  One of the blocks was generated to "include shared logic" and the other was generated using "shared logic in example design".  We have connected them together and they behave properly in simulation.  When running implementation in Vivado 2017.4, we run into a Critical Warning during Design Initialization.  The what is as follows:

 

[Shape Builder 18-119] Failed to create DATA-DRIVEN shape for instance zynq_ctrl_wrapper_i/aurora_64b66b_0/inst/zynq_ctrl_aurora_64b66b_0_1_wrapper_i/zynq_ctrl_aurora_64b66b_0_1_multi_gt_i/zynq_ctrl_aurora_64b66b_0_1_gtx_inst/gtxe2_i. Failed to add instance GT_SERIAL_RESULTS_RX_rxn_IBUF[0]_inst to a new IPAD-GTX shape. The instance already belongs to a shape and its new location conflicts with the one in the existing shape.

 

This warning is for the instance that is the slave or block that has the shared logic in the example design.  I have searched the forums and can't find enough of a similar case to help solve my problem.  Any suggestions?

This happens when you take the RX input net on one leg of the differential signal and feed it to both sides of the GTXE2 receiver.
