DC convergence

Hi,
When DC sweep range from -Vcc to Vcc*2 on the PULLUP/PULLDOWN
simulation, it has convergence problem. I try to use the alternative
method is to do an AC, but the SPICE-IBIS convertor doesn't recognize
the spice output format. So when it generated the IBIS model, it puts
out N/A in the current table. Is there anyone can help me on this?
thanks
linda
