Derrick used uuencode to encode this message. This is a UNIX utility that
take files with characters that screw up the mail system - usually
binary files or compressed text files and makes them mailable.
The limits are denoted by the 'begin nnn <filename>' and 'end' lines.
Normally to decode this sort of message you pipe it to a program
called uudecode.
I believe that there are PC versions of this available but I am uncertain
where.
To save you time I have enclosed the decoded list below. Actually in this
case it was unnecessary to encode it as the file was text only and the
encoded size was bigger.

P.S.
Will and Derrick,
You included my suggested changes except for the first one. I thought
that integrity models should be proceeded by signal - indicated by
the #signal# below.

IBIS Press Release
DRAFT 1/6/95
Rev 2.1 of IBIS Signal Integrity Model Specification Announced IBIS Standard
that Supports Early, Accurate Models for Signal Integrity Simulations of
High-speed Digital Systems Now Supports More Functions
HILLSBORO, Ore. _ December 9, 1994 _ A group of Electronic Design Automation
(EDA) and semiconductor companies today announced the ratification and
acceptance of Revision 2.1 of the I/O Buffer Information Specification (IBIS)
standard for #signal# integrity models. This release is an upgrade to the rev 1.1
specification released last year (Press Release dated Oct. 12, 1993). This
improved and refined standard adds support for ECL, dual-supply buffers,
ground bounce due to shared power rails, differential I/O, termination
components, controlled rise-time buffers, much more complete package
descriptions, improved open-side device modeling (open drain, etc.) and
reference waveforms. These enhancements are a result of more EDA companies
supporting the IBIS specification and feedback of those using rev 1.1 models.
The IBIS Open Forum has created a version 2.1 of the "golden parser" that checks
model syntax for comformance to the specification. It is currently being Beta
tested. When completed, the parser will be made freely available in object code
format
IBIS is a consistent software parsable format that semiconductor vendors can
use to specify the analog characteristics of input and output buffers. This
essential information is readily transformed into accurate models by end users
and simulation tool vendors. The resulting behavioral models enable users to
perform high-speed, accurate signal-integrity simulations of their digital
system interconnects.
The IBIS Version 2.1 specification was developed through the cooperative efforts
of simulator vendors and semiconductor companies who together comprise the IBIS
Open Forum (see the attached roster).
For More Information
For more information about the IBIS Open Forum, send an e-mail request to
ibis-info@vhdl.org. All of the documents and publicly available models are
currently accessible via the public repository of VHDL International's
Internet based machine (vhdl.org, 198.31.14.3, http://vhdl.org/). WWW,
Gopher, FTP and Telnet "Anonymous", and "guest" dial-in access, (415)
335-0110, are all available.

Support: INCASES uses the simulation program FREACS (Fast REflection And
Crosstalk Simulator) for signal integrity analysis within the
EMC-Workbench. INCASES can read IBIS Version 1.1 files and
translate the IBIS models into FREACS models. INCASES uses an
IBIS parser and an automatic process for the parametrization of
the FREACS macromodels.
Additionally, so called 'reference lists' are set-up that are
used by the interface (XLIN) between the EMC-Workbench and the
FREACS macromodel library. These reference lists consist of
circuit informations in a special language named HINAC
(Hierachical Naming Convention), where macromodel data is
assigned to pins of a component using IBIS-informations, as
well.
In this way a controlled set-up of a library is possible using
IBIS-files as basis.
Detailed information is available on request.

Support: TI has a three-pronged attack on IBIS support. TI is working on
a scheme to automatically generate IBIS models from TI Spice
simulations (TI's proprietary Spice dialect), on an automatic
means to generate C code to be linked in to TI Spice as a User
Defined Element from an IBIS model, and an automatic means to
create the Spice equivalent of the IBIS model from the IBIS
model specification.
The latter method differs from the second in that it uses
skeletonized Spice primitive elements in the form of a
subcircuit, while the second actually generates C code and
compiles it for dynamic linking.
