hI,
Could you please tell me why are the PULL UP/PULL DOWN curves seen thru 
s2iplt having kinks and spikes. They are weird and triangular.
The Power/Gnd Clamps are O.K.

I have generated the IBIS files successfully. They have passed the 
IBISCHK2 .Only warnings are there.

The cell under question is a Impedance controlled bUffer.

The foll warnings are there

TYP AC Rising Endpoints(-0.0V,  1.76 V) not within 0.035V (2%)
of (-0.70, 0.00V) on VI curves for 100 Ohms to 0V.

TYP AC Falling Endpoints(0.67V,  2.5 V) not within 0.037V (2%)
of (-0.70, 2.50V) on VI curves for 100 Ohms to 2.5V.

MIN AC Rising Endpoints (0.0, 1.5V) not within 0.031V (2%) of (-0.70V,
4.87V) on VI curves for 100 ohms to 0v.

MIN AC Falling Endpoints (0.71, 2.31V) not within 0.032V (2%) of 
(-0.70V, 4.92V) on VI curves for 100 ohms to 2.5V

Please reply ASAP
thanx
Bharat
