RE: [IBIS-Users] s2ibis2 issue

The data format issue is a known problem but usually after the IBIS file
is complied, you can edit out repeat data. I would not recommend doing
this manually.

The tool should simulate all the Typ, Min and Max conditions and then
produce a .ibs file. Do you get to that point ? If yes, then you can
edit the final .ibs file and get rid of garbage data usually at the end
of each V/I tables.

Your other choice is to try the s2ibis3 also available from the IBIS
site under:
http://www.eda.org/ibis/home/tools/tools.htm

There are also commercial tools available to do this job. Don't ask me
since I won't recommend any.

Hi Syed,

Thanks. I think you have noticed that there are some abnormal data in
the put.out
file. I also listed below:

 20 -0.999999999999998 4.98199344324096
 21 -0.799999999999998 4.12877792596131
 22 -0.599999999999998 4.01970481456261
 23 -0.399999999999998 4.01940828279669
 24 -0.199999999999998 4.02194525365832

So I am mentioning that there may something wrong. Actually I can
correct these data
manually. Do you know any tool to read these output file and gather the
data in to a ibis
file?

Best regards,
Jason
