DDRx batch simulation

Question asked by 9dc1212f-cb89-8a24-0100-014e727abccf on Nov 23, 2016

I did DDRx batch simulation in which data write is passing and data read is failing (monotonic failure)  i loaded the waveform in which signal quality is very bad, but when i simulate those nets in board-sim signal quality is good with same ibis model assignment as in ddrx batch wizard.

 

Can you tell me the difference why signal quality is varying in ddrx batch simulation and normal simulation

Thanks
