Hi,

You should be using the _fix version of the tool.

When you un'tar the download of
s2ibis2(http://www.eda.org/pub/ibis/s2ibis/s2ibis2_v1.1/s2ibis2_fix.tar.Z), read the file under ./doc/s2ibis2.txt

Look at these links for more info on IBIS:

Hi ,

I am using s2ibis2 for solaris.

While generating the curves, i find a problem with the [Rising Waveform] and
[Falling waveform]

The dv/dt_r gives me values like 0.15/-40.000p.
And the dv/dt_f also gives me 0.15/-40.000p.

What can be the potential cause of the problem ?

Also i dont seem to undersand the some concepts behind the generation of the
IBIS models. Can anyone suggest me any material/text book/link which can help me
with a complete theory of the IBIS model generation process ?

I have downloaded s2ibis2 for solaris from the website. Does the source code
need any modifications before i use them for real test cases ?

Any help will be appreciated.

Thx,
Vivek
