The ex1 files result in a DC convergence failure using s2ibis2 on Solaris
also. It is a little suspicious that the examples are setup for spectre, and
you have to change the .s2i files if you want to run with hspice. The
developer of the examples may not have tested with hspice. I believe spectre
has a reputation for better convergence than hspice.
Anyway, the keyword you need is [Iterate] in the .s2i file. This causes
s2ibis2 to generate only the files that are missing.

Hi all,
I downloaded the NT version of s2ibis2. I tried to run
the example files in the ex1 directory using HSPICE.
The pull-up and pulldown simulations are aborting
because of convergence errors.
*** error ***: no convergence in dc sweep curves at
-3.3000
Do the example files really not converge using HSPICE?
If I go into the .sp files and change the range to
something less extreme (-1 to 4) they seem to work
fine. If i go in and manually create or fix the
simulations, is there a switch to execute s2ibis to
look at the exsisting .lis files in a directory and
create the IBIS model without running new simulations?
Thanks,
Jason
