qdma的pcie 不能都放在同样的位置
pcie 和gty quad的对应关系
在nvme工程中, 把pcie错误的都放在x1y0; 工具包critical warning,工具自动把其中一个位置改成了x1y2
CRITICAL WARNING: [Vivado 12-2285] Cannot set LOC property of instance ‘design_1_i/qdma_1_support/pcie/inst/serial_pcie_top.pcie_4_0_pipe_inst/pcie_4_0_e5_inst’… design_1_i/qdma_1_support/pcie/inst/serial_pcie_top.pcie_4_0_pipe_inst/pcie_4_0_e5_inst Instance design_1_i/qdma_1_support/pcie/inst/serial_pcie_top.pcie_4_0_pipe_inst/pcie_4_0_e5_inst can not be placed in PCIE40 of site PCIE40_X1Y0 because the bel is occupied by design_1_i/qdma_2_support/pcie/inst/serial_pcie_top.pcie_4_0_pipe_inst/pcie_4_0_e5_inst. This could be caused by bel constraint conflict [/home/exxxx/nvme/proj_git313/nvme_ssd/work/src/bd/design_1/ip/design_1_pcie_0/source/ip_pcie_versal_X1Y0.xdc:103]
查看pcie在route design中的实际位置
选中PCIE->inst->serial_pcie_top.pcie_4_0_pipe_inst->leaf cells->pcie_4_0_e5_inst(PCIE40E5),选中pcie_4_0_e5_inst后右侧会高亮变成白色
在aie+nvme工程中, 直接约束成下边, gty quad的约束不生效;
