Hello, Chris,
Different EDA tools have different upper limits on currents that can be handled
by the simulator.
The warning is needed because "Spice" models that use the default series
resistance (0.0 ohms) for diodes and junction leakage currents result in large
IBIS table currents (often above 1 MegAmp). Most EDA tools don't go quite
_that_ high.
Best regards,
Lynne

If I run IBISCHK3 on many models I download I get an "Extreme currents
present" warning.
What are the limits on currents in the VI tables? I can't find it
documented anywhere.
Thanks
