12.3 ChipScope IBERT - Sweeping hangs if Iteration Dwell Time is greater than 20 seconds


According to (Xilinx Answer 37032),Iteration Dwell Time can be more than 20 seconds in the Sweeping feature. However, if I set theIteration Dwell Time greater than 20 seconds, Sweeping stops at exactly 20 seconds of the first iteration. The following erroris reported by ChipScope Analyzer 12.1:
"ERROR: it's been over 5 sec and still can't receive core update yet!Abort!"
If theIteration Dwell Time is equal to, or less than 20 seconds, the issue is gone and Sweeping works fine.
What is going on?


This issue only occurs on some specific line rates. The root cause is still under investigation.
This issue is scheduled to be fixed in ISE Design Suite 12.4.
