The tool ibis2xtk will extract a XTK model for a MOS switch from an IBIS
file, and this can be used to for simulation.
However, better results will be achieved if you have a spice model for the
mosfet switch. XTK can simulate the net using its internal 'qspice'
engine. I wrote an example of this when I was with Innoveda/Mentor
Graphics. The example can be found in either of these direcories:
$QUADHOME/demos/tlc/busswitch
or
$QUADHOME/demos/xns/busswitch
