-------------------------------- MINUTES -------------------------------------
INTRODUCTIONS AND MEETING QUORUM
Geoffrey Ellis from Cadence stated that he is involved with IBIS Version 2.1
and IBIS Version 3.0 utilities development
Nik Bannov of Avanti is working on resurrecting the Meta I/O product and on
Version 2.1 and Version 3.0 translations.
D.C. Sessions invited and introduced Gil Russell of Siemens who is Chair of
the JEDEC 16B committee. Gil's interest is in developing simulation models
for the components and methods considered by the subcommittee. Patti Rusher
affirmed that JEDEC now has full divisional status under EIA.
Jean-Claude Perrin of Texas Instruments in France participated in the
European IBIS Summit and is Chair of the IEC working group on IBIS
Simulation and EMC Modeling.
MEMBERSHIP UPDATE AND TREASURER'S REPORT
Patti Rusher had issued invoices. She reports that North East Systems
Associates (NESA) is a new member and has received payment from Mitsubishi.
She has gotten other payments, but the accounting system is still not
functioning properly for a detailed ledger report. Bob Ross and Patti will
discuss off-line some invoice duplication issues.
Patti also noted that the invoices for $2084 for ibischk3 parser source
code have been generated and mailed.
REVIEW OF MINUTES AND AR'S
The AR's will be discussed at the meeting. No corrections were noted on
the previous two sets of meeting Minutes.
MISCELLANY/ANNOUNCEMENTS
Bob Ross indicated that he still plans the Majordomo conversion when he has
time.
Later, Bob stated that Syed Huq will ask on the IBIS reflector for Roster
Updates for 1998.
PRESS AND WEB PAGE UPDATES
Bob Ross reported that the March 2, 1998 issue of EDN, pp. 14-16, has the
article "EDA Companies Tackle PCB-Board Design" which discusses several
companies with IBIS capability.
NEW MODELS AVAILABLE, LIBRARY UPDATE
Bob noted that Jon Powell had inadvertently deleted the IBIS models page
that was linked from the EIA IBIS home page. Jon expects to restore it, and
Syed Huq will ask Jon on how it is progressing.
Matthew Flora reported that he found a new Motorola link for IBIS models.
It has columns for several technologies, but currently IBIS models exist
for the LCX technology. He submitted the link later as
http://mot2.indirect.com/models/bin/logic_ic.html
He cautioned that while the tables look good, there exists some binary data
encoding or corruption in the uploaded files. Matthew has contacted Motorola
regarding this.
OPENS FOR NEW ISSUES
Bob Ross on BUG24 - Errors not issued under first of several [Define Package
Model] keywords.
Bob Ross on s2ibis2 for Win95.
INTERNATIONAL PROGRESS
- IEC 62014-1 (IBIS Version 2.1) - Patti Rusher still has not heard on the
status.
- EIAJ III (I/O Interface Model for ICs) - Bob reported that the EIAJ
subcommittee plans to have a web site in March 1998 with access to
an English translation of the Version 1.0 document.
- IEC 93/67/NP IBIS and EMC Simulation - Bob reported on the meeting of
national experts held in Paris on Friday, February 27, 1998. Bob is the
US representative. Other national representatives from several countries
participated along with the French committee within an official French
standardization body: UTE. The purpose of the meeting was to review the
committee activities and to provide input to the pending IEC 93/67/NP new
work item proposal. This meeting was conducted as a working group meeting
under IEC TC93/WG5 which was formed after IEC pushed back on the original
IEC 93/60/NP proposal. The group's charter is to produce a new work item
proposal with international concurrence for a project to standardize on
models for simulating EMI emissions and also for simulating susceptibility
to emissions. The presentation and draft document show some standardized
measurement setups and some results. The proposal is for creating
equivalent models of internal noise sources within components along with
describing some coupling to pins and supplies. The proposal also provides
for coupling from internal EMI noise sources to the device itself. The
committee had chosen the IBIS format as the basis for doing these
additions because of the usage of the IBIS format in the simulators of
interest.
The group intends to work on the proposal to consider submitting it to
IEC consideration as a new work item. Bob suggested that EDA tool vendors
would need to be involved with this activity for the committee to produce
and acceptable simulation model. Note, this committee is chaired by
Jean-Claude Perrin who called in after this report was given.
IBIS EAST USERS GROUP ACTIVITIES
Greg Edlund reported on the IBIS User's Group meeting will hold a meeting
on Thursday, March 19, 1998 at Digital Equipment. It will cover the pending
BIRD on an Accuracy and Testing Document, some tools activities, and some
reports on the European IBIS Summit.
Greg also is holding a meeting of the Accuracy subgroup on Thursday, March
26, 1998 to work on the Accuracy document. Greg stated that some of the
work by Greg and Bob Haller documented in the DesignCon98 paper will be
applied. Bob Ross recommended that this document be generated separate to
IBIS Version 3.0. It already is self-contained, comprehensive subject.
There could be some controversial areas such as test loads and methodology,
and Bob does not want the activity to bog down the progress toward IBIS
Version 3.1. So, while a BIRD proposal would be in context of issuing an
Appendix to IBIS Version 3.1, a BIRD would not be approved until the
document is completed. The document itself must focus on the methodology
and not make references to any commercial EDA product to remain within
the scope of what is allowed within the EIA rules of operation.
EUROPEAN IBIS SUMMIT REPORT
Bob Ross asked if there was any feedback on the European IBIS Summit. Syed
Huq felt it was a very successful meeting and thanked Mentor Graphics,
Cadence, and High Design Technology for providing the support. The meeting
was well attended and the 13 presentations filled the day. Syed appreciated
that all the presentations had been uploaded. Bob also felt that the Summit
was successful and stated that the people in Europe were critical for
handling the local logistics. He stated that the next European IBIS Summit
will probably be held with DATE99 in March in Munich, Germany.
DATE98 AND PCB SYMPOSIUM FEEDBACK
Bob Ross also asked if there was any feedback on the Design Automation
and Test in Europe show. In general Bob and others felt that these were
good conferences.
EDITING COMMITTEE
Bob Ross reported that he will upload the unofficial IBIS ver3_1b.ibs update
in the /pub/ibis/wip directory of eda.org. It corrects a few editorial
errors including the [End Electrical Description] and [End Board
Description] nomenclature inconsistency and other issues reported by Atul
Agarwal.
The BNF AR remains.
AR - Bob Ross generate and post a BNF for IBIS Version 3.0 (an IBIS Version
3.0 ratification AR).
BIRD44 - INTERPRETATION OF MIN/MAX/WEAK/STRONG DATA
Bob Ross reported that he contacted Andy Ingraham regarding submitting
BIRD44.1 to capture the agreements of the February 13, 1998 meeting. The
extension will use only slow/weak and fast/strong nomenclature. Andy will
also state the other keywords in Version 3.0 that might be affected by this
change. Andy indicated that he expected to do this.
AR - Andy Ingraham to issue BIRD44.1 with the changes and extensions noted
above.
IBISCHK2+ (VER 2.115) PROGRESS
As previously reported, Matthew Flora and Chris Rokusek worked together
to produce a set of executables including a DOS32 executable for ibischk2+
Version 2.1.15 which Bob Ross Uploaded on eda.org.
Also Matthew reported that fixes to BUG22 and BUG23 were added to ibischk2+
and sent to Atul Agarwal for inclusion in the ibischk3 development. Bob
asked that Matthew and Chris continue adding bug fixes to the ibischk2+
code, but that we will not release executables until we have a stable set
of fixes.
As more bugs are discovered and fixed as part of the ibischk3 project, Bob
would like Matthew, Chris, and Atul to work together to get the information
for ibischk2+ updates incorporated in the ibischk2+ code. As an example,
BUG8 is fixed in ibischk3, but has not been moved to ibischk2+ because we
did not have the resources to fix it when it was reported.
VERSION 3.1 PARSER DEVELOPMENT
Around February 20, 1998, the first release of ibischk3 was distributed to
the 12 companies that supported the development. Matthew Flora is doing
the distribution from source code that Atul Agarwal delivers to him.
Matthew has been adding a DOS32 ibischk3.exe executable so people can use
the code. Atul reported that he has included the fixes to BUG22, BUG23,
and also BUG8 in the first release. The first release included
implementations of all of the IBIS Version 3.0 features except the package
model and electrical board descriptions. Bob Ross reported that Atul has
included eight comprehensive test files for testing and checking the
ibischk3 functions that have been implemented so far. Bob reviewed these
in detail - line by line, and provided some feedback to Atul. The
ibischk-bug@eda.org reflector contains the officers and several people
involved in the parser development projects, and questions regarding
ibischk3 details raised by Atul are answered on this reflector. Atul is
now working on the package model extensions and on the electrical board
description.
Atul has just reported that he has a correction release based on issues
raised on the code so far. Bob asked Matthew to communicate with Atul
and get a new copy for distribution.
AR - Matthew Flora work with Atul Agarwal to distribute a new release of
ibischk3.
As previously reported, the invoices have been sent out to the companies
funding the ibischk3 parser development.
COOKBOOK
Stephen Peters reports that Greg Edlund and Bob Haller from the IBIS East
Users Group are now participating in the Cookbook update project. They
will provide contributions to the Test and Validation chapter.
Bob Ross suggested dropping all the ARs related to supplying examples to
the Cookbook since no one has acted on these. Everyone agreed with this,
so the example ARs are removed.
BUG19 - WARNING FOR "typ" DATA OUTSIDE "min" AND "max"
Bob Ross had been asked by Atul Agarwal whether he wanted Atul to add this
enhancement in ibischk3. Atul has already implemented some value testing
for the ibischk3 [Model Spec] subparameters. BUG19 also deals with checking
to see if typical parameters fall between the min and max parameters.
When originally issued by Paul Gregory, BUG19 was concerned with values in
the I/V tables. However per the discussion at the December 17, 1998 meeting
we felt that there were cases where such a test would issue warnings against
correct data - particularly for BiCMOS devices. However, we felt the idea
was still valid for subparameters such as C_comp, L_pkg, C_pkg and R_pkg.
However, we did not authorize that this BUG be fixed at that time. Bob
now suggested that we authorize its implementation for the above
subparameters and also for all of the Voltage Rails. The committee agreed.
AR - Bob Ross communicate to Atul Agarwal to implement the BUG19 enhancement
for the keywords and subparameters above.
BUG24 - ERRORS NOT ISSUED UNDER FIRST OF SEVERAL [Define Package Model]
KEYWORDS
Bob Ross added this new agenda item for discussion here because Atul Agarwal
issued BUG24 and also provided the solution. BUG24 applies to ibischk2+,
but this bug would get in the way of test case development for ibischk3.
Since the provided solution was simple, Bob Ross suggested that we fix it
and also add the fix to the ibischk2+ source code. Bob also suggested that
BUG24 be classified as Severe, Medium since real errors can be missed.
IBIS MODEL REVIEW COMMITTEE DISCUSSION
Bob Ross reported that one company is interested in getting some IBIS models
reviewed. Bob had asked the request be forwarded to Matthew Flora. Matthew
has not yet seen the request.
D.C. Sessions indicated that the VLSI IBIS models are available for review.
Bob has completed the permission request, and D.C. indicated that he is
ready to upload the several Megabytes of IBIS models to Bob's site for the
purpose of review. Others may also receive the models if the provide D.C.
a letter at the VLSI address on the roster.
Bob listed the complete Model Review Committee again and the e-mail
addresses are given in the minutes. The contact point is Matthew Flora.

JC-16B
Gil Russell is serving as Chair of a JEDEC subgroup of JC-16 designated as
JC-16B. Gil describes JC-16 role as standardizing on interface modeling
and testing of new I/O configurations such as Series Stub Terminated Logic
(STTL). However what is missing are simulation models for the devices for
validating the new methodologies. Gil revealed some resulting problems in
the SSTL-3 specification extensions that might have been discovered by
simulation. So SSTL-2 is still the practical level. This problem provided
a motivation to form the JC-16B subgroup. Gil presented the Scope statement
that the committee wants to generate models related to the new technologies
considered by JC-16 and to be used for verification and design support.
For background, D.C. Sessions is a member of JC-16B and suggested that IBIS
format was an ideal candidate for fulfilling the modeling requirements.
Furthermore, he suggested that EDA vendors need to participate in such model
development activities. D.C. (was) volunteered to serve as a liaison between
JC-16B and the IBIS committee, and he invited Gil to participate in the IBIS
Open Forum meeting.
Since the Scope statement was quite lengthy, Bob Ross asked Gil to provide
a text copy to be distributed to the IBIS reflector. Furthermore, Bob
invited Gil to continue to participate and monitor the IBIS activities
since the Open Forum participation public and is open to all interested
people.
D.C., Gil and Patti Rusher discussed further a suggestion that the IBIS
Open Forum meet at the December, 1998 meeting in San Diego, California.
D.C. proposed the IBIS Summit meeting be held with the JEDEC group to foster
interaction. He proposed that this replace the semi-annual IBIS Summit
meeting associated with DesignCon in January in Santa Clara. Bob Ross
indicated that this would have to be considered further since the IBIS
community has had very successful history working with the DesignCon staff
and holding meetings in January. Bob asked about other quarterly meeting
locations to see if they happened to be at other potential IBIS Summit
meeting sites, but the other JEDEC quarterly meetings tended to be at
international locations. Bob would also consider an additional joint
meeting in San Diego in December. The possibility of a joint meeting is
open to further discussion.
S2IBIS2
Bob Ross reported that he uploaded a copy of s2ibis2 for Windows95 that was
contributed by Scott McMorrow of SiQual corporation. It works with HSPICE.
Scott extended the columns to 5 decimal points for better accuracy and
resolution and increased the length of the waveform table to 251 points. He
also provides a utility to keep the first 75 points and sample the rest for
a total of 100 points - the IBIS limit (if it is needed by the EDA tool).
In this way he can get good resolution on the first part of the response
where the data is changing and also converge accurately to the final DC
value. Bob indicated that the .zip file which includes documentation is
located on eda.org under /pub/ibis/s2ibis/s2ibis2_nt. (Late note, with a
.dll file in the documentation, this executable also works with Windows NT).
Scott's e-mail is provided for comments and questions.
BIRD42.3 - MODELING CURRENT WAVEFORMS
Bob Ross reported that BIRD42.3 and related topics were discussed at the
the European IBIS Summit. However, he was not ready to discuss this at
this meeting.
BIRD45.1 - DYNAMIC CLAMPS
Arpad Muranyi reported that he met with Bob Ross and Chris Reid at Mentor
Graphics on February 11, 1998 to agree upon a proposal. Initially the
investigation was to see whether the [Driver Selection] mechanism could be
used as originally suggested by Dave Moxley. After some discussion the
group reached an agreement on a comprehensive extension that includes the
BIRD45.1 dynamic clamp mechanism and also some active latching feature.
Bob outlined the revised proposal. A new Model_type will be
proposed to cover both the dynamic Clamp mechanism of BIRD45.1, but with
fewer new keywords, and will also include the latching mechanism. Bob noted
that the structure models is exactly the same as the Bus Hold structure that
is currently being implemented in devices. Threshold subparameters for
for voltage triggering would be added to the model for typ, min, and max
in a four column format similar to those under [Model Spec].
Input and I/O models would call this new [Model] to be added to the existing
responses. Bob agreed to issue the revision as BIRD45.2.
AR - Bob Ross issue BIRD45.2 to add the dynamic clamp and latching
details under a new Model_type for a model which can be called by other
models.
BIRD46.1 - RELAXATION OF SOME IBIS FILE NAME RESTRICTIONS
Matthew Flora still needs to issue BIRD46.1 per the AR of the last meeting
to extend the filename from 8 characters to 20 characters. Bob Ross raised
the issue that BIRD46 explicitly adds the period "." character as an allowed
character in the file name for detail such as gtl.plus.ibs. Bob felt that
while such generality was possible, it was still preferred to keep the
existing restrictions for format uniformity among model providers. Stephen
Peters and others on the committee agreed. So the AR is modified to just
extend the filename size to 20 characters without adding the comment
character.
Bob also noted that a BIRD must be issued two weeks before we will vote on
it so that interested parties have time to review it.
AR - Matthew Flora issue BIRD46.1 to include references to the .pkg file
and .ebd file and to change the limitation from 64 total characters to
a <filename> limit of 20 characters and delete the references to allowing
the period "." character.
BIRD47 - REMOVE PIN NAME AS A SUBPARAMETER OF THE [Pin List] KEYWORD.
Stephen Peters issued BIRD47 to deal with an inconsistency under the
Electrical Board Description section, [Pin List] keyword. As it is
currently documented, two subparameters are documented on a separate line
in a unique format. The typical pin subparameters such as those for [Pin],
[Pin Mapping], etc., list subparameters on the same line as the keyword.
BIRD47 eliminates the pin_name subparameter and moves the signal_name
subparameter to the keyword line. Because this was a syntax change from
IBIS Version 3.0, BIRD47 was necessary.
The committee generally agreeded with BIRD47. BIRD47 will be formally voted
upon at the next meeting to comply with the two week notification
requirement. However, based on the sense of the Committee, Bob Ross will
authorize Atul to use the syntax of BIRD47 in the ibischk3 code.
KEYWORDS UNDER [NOTES] SECTION CAUSE PARSING ERRORS
In the time remaining after all of the formal agenda items including new
issues were discussed, Arpad Muranyi discussed a problem. If a keyword
is used as part of the text under the [Notes] keyword, and it is the first
entry of the line, then ibischk2+ and ibischk3 report an incorrect error.
Matthew Flora stated that IBIS requires the keywords to start on the first
column. If the [Notes] text was formated so that it was indented, but the
line started with a bracketed keyword, then this would be a bug which could be
detected and corrected. Arpad noted that there was no restriction that the
[Notes] text has to be indented. Bob Ross noted that this would be a truly
ambiguous case - you would not know if the notes text was intended to
include the keyword name or whether it was intended to be terminated by a
new keyword that was not positioned properly.
Arpad stated that he would write up the problem so we could consider it
further based on its specific description.
AR - Arpad Muranyi document the concern and send it to ibischk-bug@eda.org
[Done].
DISTINCT SIGNAL NAMES
Matthew Flora asked whether it would be considered a specification violation
or an error if the [Pin] signal_name entry was the same for different models.
This was discussed briefly. Bob Ross felt that while IBIS documents what
is intended for signal_name (the pin signal name from the component databook),
the entry is for information only. EDA tools that use IBIS models do not
rely on the entry, and there are cases where good IBIS models can be created
by just stubbing in any entry to fill the column. In the electrical board
description, the signal_name subparameter column does have some meaning for
documenting the POWER, GND, and NC pins since [Path Description]s are not
required for these pins.
Matthew felt that this was still an error for the [Pin] keyword. Bob
suggested that Matthew either issue a BIRD to suggest a clarification in the
IBIS specification or a BUG to raise formally the issue that a Warning
should be issued if different signal_names exist for the same model.
NEXT MEETING:
The next teleconference meeting is on Friday, April 3, 1998, 8:00 A.M. to
9:55 A.M. BIRD46.1 and BIRD47.1 are scheduled for votes.
