Another option would be using the Input model type, with the ESD
characteristics in the [Pullup] and [Pulldown] tables.  Of course, one would
include the pad capacitance, rail voltages, etc using the usual keywords.
The Vinh and Vinl values could be set to Vcc/2 to keep the parser happy.
 
The Input model type works for this because IBIS models only the current at
the pad, and not the internal circuitry of the receiver.

You could consider using the
"Terminator" model type.

Dear Experts,
 
I have a question regarding IBIS models.
We have an IP that is just a short with only ESD diodes connected between
supply rails. 
There is no input or output section in this IP.
Would it be possible to generate IBIS models for such an IP ?
If yes how should it be done ?
 
Thanks
Ajay
