Charles,
Rfixture is a resistor that is connected between the pad
and a voltage source called Vfixture. Kind of like a=20
Thevenin circuit.
Your example means that the 500 Ohm Rfixture resistor is
connected between the pad and 0V (i.e. GND).
I hope this helps.

Subject: [SI-LIST] Q on V_fixture in IBIS model.
As I understand it the addition of the R_Fixture and V_fixture is to
specify the loading conditions under which the waveforms are taken.=20
I am a little confused as to the physical representation. For example:
=20
In the condition=20
=20
R_fixture =3D 500
V_fixture =3D 0.000
=20
What does the V_Fixture actually mean? Is the pin grounded ?
