I use the ibis model to do data read mode simulation in Hyperlynx and Keysight ADS respectively. (signal from DDR4 SDRAM to Xilinx FPGA)
The result confounded me. The waveform in ADS is pretty good, while too bad in Hyperlynx. Besides, I found that data read waveform differs with/without PE2400.
What I mentioned above was illustrated by 4 figures attached below.
Is it normal for Xilinx read mode model? Which one I can believe, ADS or Hyperlynx?

Does frank_ma's response answer your question fully? If so, could you please accept that as the solution? Otherwise, can you elaborate if this question was not resolved?

Thanks for your reply, frank_ma!
The setting of Kintex Ibis model in ADS is right. The Kintex model is a IO model, so it appears different from Hyperlynx.
You can try it in ADS.
