Hi ALL,
I am having problems generating IBIS model for a 5v tri-state pad.
Please help to see if I've missed or mis-used something..
I sweep the output from -5v ~ 10v for both PULLUP and PULLDOWN. But got
current of 0 from -5v to 5v, and from 5v up tp 10v it gives some value
to the current. Here I have attached the config files and created IBIS
model.
spice.lib --spice model
sta.net----netlist
s2i------ config file
s2i.ibis---IBIS model
Thanks for the help.
