Is it in the ns, us, ms range? The reason I am asking is because if you sweep it too fast, you might actually be measuring parasitic capacitance on the die (I=C*dV/dt)...

I used 50 Ohm because it is MLB interface. I called it LVDS to make it clear that I was speaking about low swing differential signal. I inverted the curve polarity on the plot and made both of them ground relative to make it convenient to compare source and sink currents. In the IBIS models they were put with correct polarity, pullUp - Vdd relative, in accordance with IBIS standard and IBIS cookbook. While DC sweep on the non-inverted output was done for IV curves extraction, the inverted output was controlled by the voltage dependent voltage source v=2*Vos-v(padp), Vos ~ 1.25V (depending on conditions). Actually the issue was observed for slow and typ cases while for fast case the models are in good agreement with spice models (Vmax, Vmin, Trise, Tfall, Duty cycle matched reference waveforms).

And as Arpad says it does not at all look like a reasonable result. First, why are you loading your LVDS buffer with a 50 Ohm differential termination? Most I have seen are looking for 100Ohms. Have you inverted the pulldown's polarity? I would also expect to see the pulldown curve to have positive current between ground and Vdd. LVDS buffers have a feedback loop in them so stabilize the Vcm of the buffer. Usually this only affect the pullup IV curve but sometimes only the pulldown. This makes extracting the IV characteristics of the controlled device difficult. The feedback is fighting the curve tracer that is measuring the IV characteristics. While you are doing the IV sweep you are by definition changing Vcm and the feedback is trying to correct for this. BTW, Ip = -In. One is sourcing current and the other sinking. The sourcing should have negative currents and the sinking positive.

To model an LVDS buffer I created the following test circuit, assigned the generated IBIS model to both buffers, set one buffer as inverted output.
