I could be wrong, but it looks like the image that you posted is for a Data signal, not for the Strobe signal. The warning message states that it's a multicrossing on the strobe. Have you looked at your strobe waveform to see what's going on with that?
Thanks a lot for your help. I tried to setting the ODT on the IBIS Model right. That was the problem with the multithreshold problem.
Now i haven´t any problems with this.
The Pic was the DATA0 on the DRV and the REV.
