Hello, Bob,
The big problem with University software is that there is usually
no interest in maintenance. Students get degrees for new things,
not for fixing someone else's bugs.
Berkeley SPICE is a classic example. The UCB/SPICE web site
no longer maintains documentation on SPICE format. Bugs that
have been known about for years are still around. (Interesting to
see where this goes, now that there is an open-source version.)
Having open-source with a gatekeeper might work, if there are
enough open-source programmers interested in IBIS. The same
gatekeeper could coordinate s2ibis.
Best regards,
Lynne

I think I can answer the following:

I think for an open source project to be viable, there
has to be a gatekeeper and a group of committers
that accept fixes.
If I did make a fix to s2ibis2, where would I send it
to get it into the "official" version? I just visited
the University of South Carolina website for the code,
and although no dates are given, the fact that s2ibis2
still only supports IBIS 2.1 suggests that it's been a while
since there has been any University interest in this
project.
In fact, on Mentor's own website are some updates
to s2ibis2: a port to Linux contributed by Cisco, and
a fix or two contributed by others. So I don't think
you can claim there is no OS interest in s2ibis2. I
think that if there were a perception that there was
an active gatekeeper, perhaps several other fixes
would be submitted as well.
