Lior,
The *-fixture parameters are used when you generate the
waveform tables to load the driver with known loads.
The *-ref parameters tell the simulator how to load
the IBIS model when running simulations with it. These
supposed to indicate the load at which the buffer's Tco
was derived with in the data sheet.
I hope this helps.

Subject: [IBIS-Users] Differences between '*_fixture' & '*_ref'
parameters
Hi,
While creating an ibis model, I encountered a misunderstanding
regarding the differences between the '*_ref' parameters and the
'*_fixture' parameters.
It seems like both are being used for loads.
In addition, I have noticed that the '*_fixture' parameters are being
used only at the 'rising/falling waveform' simulations.
Does anybody know what the differences are ?
Thanks in advance,
