Req for Info: Differential Buffers

The typical construct for converting Spice models to IBIS -- namely,
Spice deck fixtures for producing V/I and V/T curves, do not appear
directly relevant for converting differential buffers.

For example, if the non-inverting transmit buffer output is connected to
the S2IBIS2 fixture, how should the inverting output be connected?
Please note that the manner in which the inverting output is connected
does have an impact on the response of the non-inverting output.

If the non-inverting output is ignored, then the results do not
correlate to the actual buffer behavior because of the tightly matched
current sourcing and sinking of the respective outputs. If the
non-inverting output is connected to something, what is it for both the
V/I and V/T fixtures?

In short, what is the established procedure for differential buffers?

Thanks in advance for any assistance,
