Hi all

        I am facing problem related to convergence. I even modified the
(.options),but iam still facing a problem.
 
I am using HSPICE simulator,s2ibis2 tool. I even used converge in the option but the problem was still there.
 
some of the specification i used are:
 
1. pull-up vg -- 1.8v
 2.pulldown -- 0v
 3.powerclamp -- 3.3v
 4.gndclamp 0v
 5.voltagerange 1.8v
 6.vih 1.8v
 7.vil 0v
 
I really wanna know ,whether the convergence problem occurs due
to spice-model .

regards with anticipation

Thantry
