This issue only affects users who use IBERT under the following conditions:
The 200 MHz oscillator that is on the KC705 and VC707 development boards uses a LVDS_25 I/O Standard. The KC705 and VC707 Board Configuration Setting automatically selects a DIFF_SSTL standard, which is incorrect.
To work around the issue, manually select the LVDS_25 setting for the system clock instead of DIFF_SSTL to ensure proper operation of the IBERT design.
This issue is scheduled to be fixed in ChipScope tool version 14.2.
