This is a known issue to be fixed in a future release of the core.
To generate the core for VC709, select the correct part and package for VC709 and select VC707 board in the core customization GUI; this will generate the core for VC709. In a future release, the VC707 option will be replaced by VC709.
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.
