"kintexu_grp1.ibs" DDR4 IBIS model definition

i am traying to simulate DDR4 link using kinetic ultrascale as the memory controller
i had a problem identifying the proper IBIS model for different signals (DQ, DQs, Add, Cmd, etc).

for example what this model "HP_SSTL12_S_OUT40_IN40" is for? 

i have hard time finding this information.

i appreciate your help

This model is not the one you need. Normally the dci version of the sstl12 IO is used.

You can get vivado to write ibis model for your specific pinout and interface.
