SN65LVDM31: Issue using SN65LVDM31 IBIS Model

Tool/software:

Hello,

We are having an issue using the SN65LVDM31 IBIS model while simulating a 100MHZ clock signal. We are seeing a runt pulse in the first pulse which seems to be due to the output driving both P and N legs of the diff pair high, than correcting itself. I substituted this SN65LVDM31 driver with a SN65LVDS31 IBIS and saw no such issue and the signal behaved as I would have expected. 

Is there a known issue with the SN65LVDM31 IBIS? Is there any way to get an updated IBIS model if that is the case.

Thanks
