描述

Version Found: DDR4 v7.0

Version Resolved: See (Xilinx Answer 69035)

When simulating a MIG UltraScale DDR4 design targeted for tCK=833ps, speed bin=833, and using a Micron memory model, the following error message might be seen:

ERROR:tCK SPEC_VIOLATION spec:TS_938 to TS_938 loaded:TS_833 @3983149.

解决方案

This violation is seen because of an issue with the Micron memory model using the wrong speed bin parameters.

Please contact Micron for a solution and timeline for when this issue will be fixed.
