MIG 7 Series RLDRAM3 - Simulation - Calibration failures due to issue with memory model


Version Found: MIG 7 Series v2.0 Rev 3
Version Resolved: See (Xilinx Answer 54025)

At high frequency it is possible for calibration to fail as a result of different phase alignments between the read clock (QK/QK#) and read data (DQ) in the memory model and during calibration.

This is an issue with the Micron memory model and only occurs at higher frequencies. 


This issue only affects behavioral simulations and can be safely ignored as this will not cause problems in hardware.

If a work around is needed please contact Micron or open a webcase with Xilinx Technical Support.
