UltraScale RLDRAM3 - hardware failures can occur at lower frequencies of operation


Version Found: RLDRAM3 v1.0

Version Resolved: See (Xilinx Answer 69037)

Intermittent calibration and data errors might be seen when operating the UltraScale RLDRAM3 IP at low frequency ranges. 

This issue only affects RLDRAM3 IP and only within the 300-333MHz frequency range.


To work around the issue, increase the operating memory frequency to above 333MHz.
