I am configuring a Virtex-7 FPGA Gen3 Integrated Block for PCI Express v2.1 core in Vivado Design Suite.
However, the field to set "VF Device ID" in the PF1 SRIOV Config tab is grayed out in the GUI.
This is a known issue scheduled to be fixed in a future release of the core.
To work around this issue, assign the required value manually in the source file.
Note: "Version Found" refers to the version where the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions. Revision History: 08/04/2013 - Initial Release
