However, why at time = 702051705 ps , simulation waveform shows 0 , but the modelsim console transcript log shows 1 instead ? I have thought about DQS centering in this case, but phase-shifting DQ to both left and right by 90 degrees still give contradictory result. Remember that timing cursor corresponds to the fourth piece of data being read during MPR_Read_function mode. Upvote 0 Downvote
