To achieve optimal timing QoR and minimize routing congestion when designing with HBM and PCIE4C, Xilinx recommends using the PCIE4C sites that are farthest away from the 32 HBM AXI interface in SLR0. In the following figure, these sites are PCIE4CE4_X0Y1 and PCIE4CE4_X1Y1 indicated by the green arrows.
