Subject: Re: [SI-LIST] : modeling languages (was: receiver jitter)
Instead of arguing IBIS
vs. SPICE we (the industry) ought to be working towards a modeling language
that supports the circuit simulators nodal descriptions while at the same
time
allowing a higher level behavioral description of the buffer (or receiver)
itself.

I couldn't agree more. Which leads me back to one of my previous postings
to the IBIS email reflector which I wrote to collect some ideas on what kind
of improvements need to be done in IBIS to make it useful for those who
can't
use it today. Thanks to those who contributed we received some really good
suggestions.
Here is a thought provoker again:
In the next revision of IBIS or even ANY-SPICE!!! :-) I would like to see a
combination of all of the good features in every tool and modeling language
I have ever seen. Some of the items that come to my (tired) mind now are:
flexibility, nodal description
speed, accuracy
any level of model abstraction
full transistor with process information
table driven transistor (IMIC)
behavioral primitives (from inverter, to any level of
buffer building blocks, full buffer, etc.)
allow any type of expression for the above between each of its
nodes
(S-parameters, math formulas, matrixes, etc.)
power plane modeling, field solver capabilities including
frequency dependencies (and dielectric losses)
return path modeling
package and on-die power distribution modeling
behavioral receiver modeling (why not...)
arbitrary automated measurements
good preprocessing interface
full board extraction
schematics
parameterization
automatic variable sweeping capability (including Monte Carlo)
good post processing interface
plot any node voltage or current and measurement result
against any other node V or I and parameter
histogram, or statistical plots
and the list could go on if I didn't want to go home...
Anybody want to contribute to the list, or some more specifics on how to
go about some of these items?
