Intros of new IBIS participants
Dave Moxley of AT&T Global Info Systems. He is a model user interested in IBIS
models of ASICs and other components.

Treasurer's report
The current balance is $4,191.64. All income is from Golden parser license
sales and $10 interest.

Review of previous meeting's minutes
There were no corrections made to last month's minutes.

Miscellany/Announcements
None.

Opens for new issues
None.

Golden Parser, 2.1
Paul Munsey estimates that the 2.1 Golden Parser work will be 2x the 1.1 parser
effort. Paul plans to work with another programmer. They will each work on it
part-time. He expects the work to be 6 weeks full time. He could have a Beta
version mid September. Then, another month for testing, and 2 weeks for final
S/W, final release in October. Jon Powell wants the parser by the end of
August/early Sept. After discussion, we agreed to have Paul write a short
proposal with detailed schedule. Paul may consider hiring another programmer to
get the work done earlier. We will review the proposal at a special phone
conference on 7/8/94.

AR Derrick: Send approved 2.0 spec. to Paul. DONE.

AR Paul: Write 1 to 2 page proposal and post it to the reflector
(ibis@vhdl.org).

AR Derrick: Secure a bridge number for the 7/8 review meeting.

EIA Presentation/Discussion
Patty Usher, director of the EIA Electronic Information Group, presented an
overview of the EIA (Electronics Industry Association) organization. EIA is
company-based standards organization. Her group is an "ideal niche" for IBIS.
We'd be a working group/sub-committee under her group. This would give us the
umbrella of a recognized standards organization.

There would probably be a committee fee to cover the administration of the
balloting, press releases, meetings and such, estimated at $100 per company. We
would retain control over sale of the spec. and licensing of the Golden Parser,
we would set the costs, depending on how much revenue stream we need to operate.
 Although the EIA would own the copyright on the spec., we would retain near
autonomous control with support service from the EIA, which is funded by the
member corporations.

The EIA offers two options for ratifying a standard, an "interim standard" with
a two-year life (one month limited ballot) and a "proposed standard" with a
60-day public ballot. We would be required to answer all negative ballots,
resolve them to the best of our ability, then it would go to ANSI. The process
takes at least 100 days. The EIA uses one-company, one-vote balloting.

Jon P. expressed concern over the cost of EIA affiliation because of the cost of
EDIF. Randy says that EDIF committee set those costs. and that we wouldn't have
to set ours nearly as high.

If we decide to enroll with EIA, we need to send Patty a letter of intent to get
the process started. She will forward it to EIA Legal and then would set us up
as a committee.

A decision by this body is possible at the next meeting.

Press updates
A press release is planned for Ver. 2.1.

Progress toward enlisting new IC vendors
We are executing the 7-part plan discussed at DAC (see 6/9/94 minutes).

New models available
As was decided at DAC, companies can post notices of model availability even if
they are not posting the models themselves. Contact Derrick Duehren for posting
details.

Randy Harr expressed some concern about control of the vhdl.org directories.
Consensus is that control is sufficient for now (write access is limited to
Randy and Derrick).

Jon P. expressed concern that the models are not policed (verified against the
Golden Parser) before posting to vhdl.org. He wants a formal IBIS Librarian
position established, possibly rotating among participants. We will add a
discussion of an IBIS Librarian with duties and responsibilities, who, etc. to
next meeting's agenda.

Jon reported that Motorola is reevaluating their decision to release PowerPC
IBIS models.

No other semi vendors were on-line to report.

IBIS 2.0 ratification/DAC residual issues?
None.

IBIS Cookbook
Stephen reported that all comments received to date have been incorporated and
Stephen added the ramp rate and ground/power clamp 2.0 issues. Stephen will
publish it as a 0.9 draft on vhdl.org in a variety of formats. Stephen was
elected to be the Cookbook Czar.

AR Stephen: Post the cookbook ASAP.

Levels of Support
Much discussion brought out several strong opinions on various sides of this
issue. Some good suggestions were aired:

o Simulator vendors need to communicate to the customers what level of
   support they provide.

o An app note could be written to address what information a user needs
   to do good simulation, or such things could be in the model itself.
   Any volunteers?

o Dave M. suggested that the GP output a table of 2.0+ (beyond 1.1)
   keywords and display all the notes and copyright information (on
   screen).

AR Paul M: Add beyond 1.1 keyword display to the requirements list for the
   2.0 Golden Parser.

Spice-to-IBIS Converter
Scott : The interface works well, but it has some problems and only supports
Pspice and V1.1, not Berkeley spice. A copyleft statement will be included to
keep it non-proprietary.

Pending BIRDs (BIRD 16?)
Not discussed.

Formal BNF notation (BIRD?)
Not discussed.

High freq. and EMI
Not discussed.

Phased turn-on/off of multiple devices
Not discussed.

Wrap-up, Next Meeting Plans
A Golden Parser discussion meeting will be held 7/8/94, and the next general
open forum meeting is will be held 7/15/94. Bridge numbers will be posted to
the reflector.
