Add a “Constant” from the IP Catalog and configure it to output 0 (low). We’ll use this to tie low the “INTX_MSI_Request” input of the AXI-PCIe block. Connect the constant’s output to the “INTX_MSI_Request” input of the AXI-PCIe block. Add a “Utility Buffer” to the...
Sharing the sys_clk from the PCI Express IBUFDS_GTE4 between two or more components is causes routing issues. This article is part of the PCI Express Solution Centre (Xilinx Answer 34536) Xilinx Solution Center for PCI Express Solution Follow the steps below to support clock sharing in Vivado...
This fixes an issue where sharing sys_clk from the PCI Express IBUFDS_GTE4 between two or more components causes design not to route. This must be done prior to "Open Example Design". With this patch, after "Open Example Design" Step 3 and 4 will be executed automatically. ...
