Draft 0.2
Wednesday
Opening and Introductions
Dick Somes, DEC, called
the meeting to order and asked members to introduce themselves.
After introductions the minutes from the previous meeting were
reviewed. There being no changes a motion was made, seconded,
and passed all in favor to accept the minutes as written.
Agenda Review
The agenda was reviewed.
Several changes were made to accommodate speakers who would not
be available at their appointed time.
Call for Patent Disclosure
Dick Somes read the VSO
Patent Disclosure Policy and asked for the disclosure of any patents.
John Rynearson, VITA, presented a patent notification that he
had received via the VITA reflector. The patent in question is
No. 5,388,231 and apparently deals with a method of increasing
the data transfer rates on a VMEbus backplane by transferring
data on both edges of a strobe. John accepted an action item
to get a copy of the patent and report to the group. The patent
was filed in 1989 and issued in 1995. No other patents were disclosed.
VITA Congress Announcement, John Rynearson, VITA
John reminded attendees
of this years VITA Congress scheduled for October 7-9 in Brussels.
The technical program chaired by Chris Parkman, CERN, is almost
complete and will cover a wide range of topics of interest to
VMEbus manufacturers and users. Those interested in getting more
details should contact the VITA office in the US or Lyndsey Carter
with GGH Marketing in the UK, +44-1329 846166, (lyndseyc@gghnet.demon.co.uk)
General Announcements.
Paul Fischer, FORCE, noted
that a BusNet task group meeting would be convened immediately
in the Saguaro 2 room upstairs and asked all those interested
to attend.
The following task groups
announced meetings apart from the main VSO meeting: VITA 10 --
Skychannel, VITA 1.x -- 9U x 400 mm VME64 Format, and VITA 20
-- CCPMC.
Canvass Ballot Review, John Rynearson, VITA
John noted that two standards
VITA 4, IP Modules, and VITA 13, HIC, have been recognized by
ANSI as official standards. John congratulated Jerry Gipper,
Motorola, and Kim Rubin, GreenSpring Computers, for their excellent
work on VITA 4, IP Modules, and Colin Whitby-Strevens, SGS-Thomson,
for his excellent work on VITA 13, HIC. Both standards are available
from the VITA office. Recognition of these achievements are being
planned for the November meeting.
John noted that VITA 10,
Skychannel, is in negative ballot review. Richard Jaenicke planned
to meet with available task group members off-line to go over
negative ballot comments.
John stated that VITA 12,
M-Modules was in pre-canvass ballot solicitation. Because a majority
of the balloters were manufacturers the ballot was being delayed
until more non manufacturers could be solicited. John indicated
that the ballot should begin within four weeks.
Executive Director Report, Ray Alderman, VITA
Ray noted that an agreement has been reached with the IEEE regarding
copyright issues on the VMEbus specification. See attached letter
for specific details.
Ray stated the VITA has joined JTC1/SC26 committee with John Rynearson
as the primary member and Dick Somes and the alternative member.
JTC1/SC26 plays an important role in coordination of standards
with various European groups.
Ray brought members attention to the current issue of Electronic
Design magazine and its special VMEbus section.
Ray remarked that the business climate for VME remained favorable
and that the total market for just boards in 1995 was probably
over 1 billion dollars.
Ray noted that the Real Time Group was sponsoring a exhibit and
technical session to take place in Santa Clara in January and
that the VSO had the option of having its meetings on Monday and
Tuesday of that week at the same location.
Ray stated the one of the agreements with the IEEE was that the
IEEE would reaffirm IEEE 1014-1987. After discussion it was determined
that the reaffirmation should be supported as is without recommending
any changes -- even minor typographical ones. Ray noted that
Chris Parkman, CERN, is chairing the IEC committee to update and
harmonize IEC 821 with CENELEC and that eventually this effort
will address the VME64 specification.

VME2000 LLC Administrative Report, Ray Adlerman
Ray explained that the VME2000 LLC was a limited liability corporation
whose purpose was to carry out a simulation of the VME64x backplane
to insure reliable operation. The group is composed of 17 companies.
Robert Cutler, AMP, has been contracted to carry out the simulation.
Membership in the LLC is $3000 and membership is still open.
Admittance of new members requires majority approval of current
members. Contact Ray Alderman at VITA, 602-951-8866, (exec@vita.com),
if you are interested in VME2000 LLC membership.
VME2000 LLC Technical Report, Wayne Fischer
Wayne noted that the simulation has identified signal edge rise
times as an important contributor to overall system noise. Wayne
stated that the LLC is still discussing how to deal with this
issue and that he would report to the group on Thursday what the
LLC had decided.
David Wright, Hybricon, asked to be granted voting privileges
for the current meeting. David is a new employee with Hybricon,
but has been involved with VME and Futurebus issues for a long
time. After discussion in which several members spoke in favor
of granting voting privileges to David, and hearing no objection
David was granted voting rights for this meeting.
VSO Policies and Procedures Discussion, John Rynearson
At the previous VSO meeting an issue was raised regarding alternative
standards paths. While researching this issue several other issues
with VSO P&P became apparent and were presented to members.
The first issue was the lack of an explicit method to change the
VSO P&P. Robert's Rules of Order states that a 2/3 majority
is a common requirement for an assembly to change its bylaws.
While all members agreed that a 2/3 majority was appropriate
much discussion ensued regarding voting requirements. Some members
felt that P&P should be voted on at a regularly scheduled
meeting using the attendance requirement of 2 meetings out of
the previous 4 while others felt that previous attendance to vote
on procedural issues should not be a requirement. After discussion
the following motion was introduced, seconded, and passed all-in-favor.
Resolved to have John Rynearson construct language for a method
to change the VSO P&P. This method will be submitted for
review at the next VSO meeting.
The next issue brought up for discussion involved the relationship
between the task group and the main VSO body. The question discussed
was "Does the main VSO body have the ability or right to
impose binding direction on a task group?" If yes, then
Dick Somes felt that language was required in the P&P stating
how this binding direction was given and the consequences if such
direction was not followed. John Rynearson presented an alternative
view that some activities (e.g., VME64x) were of interest to everyone
in the main VSO body and that when discussions were held on these
activities the task group was essentially a "committee of
the whole". John pointed out that this interpretation did
not require a set of rules regarding the relationship of the VSO
main body to task groups. John noted that task groups of limited
interest to the main body of the VSO could always ask for guidance
from the main body. Guidance could be considered binding or not.
John reminded attendees that the task group ballot, open to anyone
in the VSO, was the method used to reach consensus on the development
of a standard. More discussion ensued. Another method proposed
to resolve this issue, was to consider task group discussions
within the main VSO body to be actual task group meetings. In
other words, the main VSO meeting would be adjourned and the task
group meeting would then be convened. When task group business
was completed, the task group meeting would be adjourned and the
main VSO body would be reconvened. This process would also eliminate
the need for rules regarding VSO main body votes binding task
groups. Dick Somes stated that he considered the consensus of
the group to be that the main body did not desire language in
the P&P binding task group direction by main body VSO action.
John Rynearson noted that certain clarifications in the VSO P&P
were required and that he and Dick would address these areas in
the next update of the P&P.
The group also discussed task group ballot lists. Wayne Fischer
noted that he was using the attendees list for VSO meetings as
ballot and notification lists for the VME64x specification. Certain
members who had not attended all meetings were not receiving new
drafts and ballots for VME64x when they assumed they would. Wayne
stated that he had a lot of trouble with non returned ballots.
After more discussion it was decided to reconstitute the VME64x
task group ballot list and to add an observer status to the task
group list. Observers would receive all information except they
were not required or expected to ballot.
*** LUNCH BREAK ***
VME64x Report, Wayne Fischer, FORCE
Wayne Fischer has put a copy of the draft for VME64x on FORCE's
web site in PDF format and recommends PDF as a method for the
inexpensive distribution of draft standards. Joe Bedard, HP,
noted that there are some problems with different revisions of
Adobe Acrobat Readers.
Wayne moved that the main VSO meeting be adjourned and that a
VME64x Task Group meeting be convened. The motion was seconded
and hearing no objection, Dick Somes declared the main VSO meeting
to be temporarily adjourned. The VME64x Task Group was called
to order by chair Wayne Fisher.
Wayne Fischer requested voting rights for Mike Hasenfratz, Micro
Memory. After discussion and hearing no objection, Mike was extended
voting rights for this meeting.
Wayne noted that bolding and capitalizing SHALL in rules seemed
like overkill and caused draft standards to be hard to read.
Therefore he asked for the group's approval to leave shall nonbolded
and not capitalized. No objection was heard.
Wayne noted that Rule 2.21 currently specified a value of 100
ma and recommended that the value be changed to <= 1 ma. David
Wright noted that lower values were being required by some European
health organizations and suggested the group consider a lower
value. After further discussion, the group decided to set the
rule value at <= 1 ma and to follow that with a recommendation
of <= 100 ua if possible.
Another request was to redraw Figure 6-1. No objection was noted.
Wayne raised the issue of whether or not ETL and 2eVME should
be left in or removed from the VME64x draft standard. Much discussion
followed. Some members felt that it was important to complete
the draft standard as soon as possible and leaving 2eVME out would
speed that process. Other members felt that the document must
include a faster protocol and that leaving 2eVME out would cause
the development of 2eVME to drag on. Paul Vena, CSPI, asked why
it was important to keep 2eVME and ETL in the VME64x draft standard.
Tad Kubic, Dawn, stated that his customers didn't feel comfortable
adopting technology that was not standardized. Jerry Gipper,
Motorola, noted that many companies produced and sold VME64 capable
boards several years before the VME64 standard was approved.
Joe Bedard moved to take 2eVME and ETL out of the next draft of
VME64x. His motion received a second. Additional discussion
followed. Several members voiced their concern that for VME to
remain viable, 2eVME was required. A motion to end discussion
was received and seconded. Hearing no objection the motion on
the floor was voted upon with the following results: 5 FOR, 15
AGAINST. Therefore the motion to remove 2eVME and ETL was defeated.
*** BREAK ***
Jing Kwok, DY4, asked to speak regarding the issue of keying on
conduction cooled boards. He noted that he and several other
members would negative ballot the next VME64x task group ballot
unless a satisfactory interoperable method of keying could be
found. Jing noted that using keying through the P0/J0 connector
reduced the pin count to 80 and would make convection cooled boards
and conduction cooled boards incompatible. He stated that conduction
cooled applications also required as many I/O pins as possible
and asked for help in finding another solution to this problem.
Mike Munroe, ERNI, who was not at the meeting had provided some
plastic keying parts that were currently used with 96 pin DIN
connectors. However, most felt that this method was not possible
because of the spacing required for the new 5 row 160 pin connector.
Dave Robak, Harting, stated that a method of keying using a machined
metal part on the side of the connector might be possible. He
noted that it would prevent the card from being fully seated,
but might not prevent pins from mating. The following members
volunteered to work together on a "tiger team" to come
up with a conduction cooled keying method. This group will report
back to the group at the November meeting. Tiger Team members
include: Joe Bedard, HP, Dave Robak, Harting, Elwood Parsons,
AMP, and Roger Hinsdale, IBM.
Martin Blake, VERO, spoke regarding a backplane dimension problem
with the new J0/P0 connector. See attachment for the issue and
Martin's proposal. Martin noted that he is not asking for a vote
today, but simply providing information for members to consider.
Wayne noted that updates to the CR/CSR chapter are still pending.
Bob Downing stated that the 2eVME protocols have been reviewed
and that only one issue surfaced that requires resolution.
A motion was made to move VME64x to task group ballot. The motion
was seconded and voted all-in-favor with none opposed. Wayne
agreed to reconstitute the task group ballot list. A sign-up
list was sent around and the task group ballot will be announced
over the vita reflector. All vso members may ask to be on the
task group ballot. Wayne stated that he plans on mailing the
ballot by Monday, September 23. The 30 day ballot will be due
Friday, October 25.
Wayne adjourned the VME64x task group meeting. Dick Somes reopened
the VSO meeting.
Dave Robak, Harting, gave a status report on the 160 pin connector.
See attachments for complete details. The IEC proposal to add
this connector to the DIN spec will be discussed next week.
VITA 4.1 Report, Wayne Fischer
Wayne explained at the last VSO meeting that Ray Alderman has
requested a statement from PICMG giving indemnification to VITA
regarding references specifying certain user pins in the Compact
PCI (cPCI) specification. Wayne noted that the PICMG board did
not feel it could provide such indemnification, but instead would
set up a registry for user pin assignments. As a result Wayne
stated that he would remove all references to a cPCI pin assignment
in VITA 4.1 and would work with the negative balloters to resolve
any remaining issues.
VIPA Report, Bob Downing, UIUC
Bob explained that VIPA stands for VMEbus International Physics
Association and that its goal is to provide commonality of use
for VMEbus in physics applications. VIPA is made up of representatives
from various physics labs around the world including Fermi, CERN,
SLAC, Brookhaven, and KEK. The group has developed a recommended
practices guide for VMEbus in Physics. The draft standard is
available from the following web site: http://www-vipa.fnal.gov/vipa/doc2.htm.
VITAL Update, Brad Shaw, McDonnell Douglas
VITAL is a DARPA technology reinvestment project and is concerned
with improving performance and reducing life cycle costs in airborne
vehicles. One method of reducing life cycle costs is to use off-the-shelf
technology. The VMEbus is viewed as a major component of the
VITAL effort. For more information, see the attached presentation.
VITA 6.1, SCSA Extensions, Lou Francz, Dialogic
Lou reported the task group ballot results. Out of 18 ballots
sent out, 14 (78%) were returned achieving the 75% requirement.
Out of the 14 returned ballots, 13 were affirmative and 1 was
negative, thus meeting the 75% or greater affirmative requirement.
Lou thanks those in the task group for their participation and
asked that VITA begin the canvass ballot process for SCSA Extensions.
VITA 22, CellBus on VME, Lou Francz, Dialogic, for Dan Upp, TranSwitch
Lou stated that Dan was unable to attend the meeting but was planning
on being at the November meeting. Lou reviewed the goals of VITA
22 and suggested that interested individuals contact Dan for additional
information.
VITA 21, V-Net
No report was given.
The meeting was adjourned for the day.
Draft 0.2
Thursday
Opening and Introductions
Dick Somes, DEC, called
the meeting to order and asked members to introduce themselves.
General Announcements
Wayne Fischer said that
he had been asked by Warren Andrews to help with the technical
program for the RTC conference being planned for the third week
in January 1997. Wayne asked members who would like to participate
to contact him.
The group then discussed
future meeting locations. The next meeting will be held in San
Diego at the Doubletree Carmel Highland Resort on November 13
and 14. The January 1997 meeting is tentatively scheduled for
Monday and Tuesday, January 13 and 14. The bulk of the meeting
is planned for Tuesday with Monday afternoon available as overflow
time. The meeting will take place in Santa Clara in conjunction
with the RTC conference.
The March meeting is planned
for either the Orlando or St. Petersburg area. The May meeting
will be held in Phoenix. The July meeting will be held in the
north. Suggestions included Ottawa, New Hampshire, Minneapolis,
and Vancouver.
VME2000 LLC Simulation Report, Wayne Fischer, FORCE
Wayne stated that the LLC met before the VSO meeting and discussed
the next steps for the simulation. One of the goals for 2eVME
is to achieve incident wave switching. Therefore, Robert Cutler
has been ask to design a circuit that will be placed between
ETL drivers and the backplane to ensure incident switching in
all cases especially for strobes. This circuit will slow the
signal edge insuring incident wave switching and will also reduce
overall noise in the system.
VITA 11, Autobahn and VITA 14, CXC/Modpack
Hermann Strass, Technology Consulting, could not attend the meeting.
John Rynearson noted that Hermann was continuing to resolve issues
from the previous task group ballots and planned to attend the
November meeting.
VITA 17, Front Panel Data Port, Jonathan Jones, ICS
Jon was not able to attend the meeting but will report on FPDP
at the November meeting.
VITA 18, VME on SEM-E, Mary Mosier, NSWC
Mary noted that she had received no comments on the alternative
pin assignments presented at the July meeting. She solicited
comments and stated that a decision would be made by November.
VITA 20, Conduction Cooled PMC, Jing Kwok, DY4
An off-line task group meeting was held and the group submitted
draft standard 1.1 for review.
VSO Procedural Discussion, John Rynearson
Continuing the discussion from Wednesday, John stated that at
the July meeting the question had arisen regarding alternative
standards paths. In other words, could a standard developed within
the VSO be taken to another formal standards body such as ISO,
IEC, CEN, etc. Additionally, did it make sense to have a standalone
VSO or a VITA standard? Discussion ensued. Some members felt
that it should be VITA's stated policy that all standards developed
within the VSO be taken to ANSI. Other members felt that the door
should be left open to other standards organizations. Similarly
some members liked the idea of a VSO or VITA only standard while
others pointed to problems with trade association or consortia
developed standard. No clear consensus developed so no action
was proposed.
IEEE P1101.10, P1101.11 Report, Frank Hom, Electronic Solutions
P1101.10 and P1101.11 are standardization efforts taking place
under the IEEE. Status reports are provided to the VSO because
of member interest. Frank noted that draft 5.1 of P1101.10 is
currently in IEEE RevCom. Eike Waltz, Rittal, and chair of P1101.10,
has received a letter from DASA stating their willingness to license
certain technology referenced in IEEE P1101.10 for a reasonable
and non-discriminatory fee.
Frank noted that P1101.11 draft 1.0 is available for review and
asked individuals interested in being on the working group to
contact him.
VITA 1.x, VME64 9U x 400 mm Format, Bob Downing
Bob reported on the completed task group ballot. Out of 24 ballots
total, 18 were affirmative, 1 was negative, and 5 were not returned.
The negative ballot concerned connector numbering. Paul Vena,
CSPI suggested that separate numbers be used to distinguish DIN
connectors from hard metric connector options. This suggestion
was accepted and will be included in the next draft standard.
Bob also noted that he had added an annotation to each rule,
recommendation, etc. to improve readability. As a result of these
changes, the 9U draft standard will be reballoted.
IEEE 1101.2 Report, Kim Clohessy, representing DY4
Kim noted that IEEE 1101.2 was up for reaffirmation within the
IEEE and asked whether those present felt it should be reaffirmed
or revised. IEEE 1101.2 is the conduction cooled standard for
DIN style modules. Those interested in this effort should contact
Kim Clohessy (kim_clohessy@oti.com).
High Availability VME Meeting, Lou Francz, Dialogic
Lou asked that the VSO meeting be temporally adjourned so that
the H.A. VME meeting could be convened. Dick Somes hearing no
objection adjourned the VSO meeting and Lou Francz called the
H.A. Meeting to order.
Lou reviewed the of goals of H.A. VME. The goal is to provide
an architecture that will allow system integrators to construct
systems to whatever level of availability required for a specific
application. For example, Lou noted that the telecom industry
uses the four 9's requirement (i.e., downtime can only be 4 minutes
per year, .9999).
One area discussed was the status of the utility communications
channel (UCC). The UCC can be used to diagnose and potentially
correct faults on the parallel VMEbus. A straw vote designated
1149.5 as the protocol for the UCC at a previous meeting. However,
one of the provisions for acceptance of 1149.5 was the general
availability of silicon. Bob McKee noted that Silicon Devices
has decommitted from making an 1149.5 compliant device. Therefore,
the use of 1149.5 for the UCC will be reconsidered. Other candidates
are: USB, CAN, and Access Bus. Bob requested that terminology
used by H.A. VME be consistent with ANSI/VITA 3-1995, BLLI. Doug
Endo, Hughes, expressed concern that members keep in mind software
requirements for H.A. VME. The group discussed the possibility
of an inexpensive bus monitor card that would plug into the back
of a VMEbus system and provide fault detection.
Lou asked that another H.A. VME meeting be held in November.
Lou adjourned the H.A. VME meeting.
*** LUNCH ***
Dick Somes reconvened the VSO meeting.
VITA 19, BusNet, Paul Fischer, FORCE
Paul stated that the BusNet task group had met for the last two
days. A number of house keeping issues were resolved. The group
decided to break the effort into multiple draft standands: 19.0
summary, 19.1 busnet access (current draft standard), 19.2 logical
link control. The task group plans to have a final draft available
by January 1997. A breakout room will be required for the November
meeting.
Study Group, VISION, Jim Pangburn, Fermi
VISION specifies an API for software running on a master. VISION
is object based and network-enabled. "Components" are
used to implement slave access mechanisms. Jim noted that LeCroy
has expressed interest in sponsoring this effort. Therefore one
more sponsor is required for task group status. Any VITA member
that is interested in this effort should contact Jim Pangburn,
Fermi, at pangburn@fnal.fnal.gov.
Action Items
John Rynearson and Dick Somes will put together a method for revising
the VSO P&P and submit it to November attendees with 30 days
notice for discussion at the November meeting. Task group ballots
for VME64x and 9U VME64 will take place. There will be an VME2000
LLC meeting before the November VSO meeting. Wayne Fischer asked
that the issue of non responding balloters be reviewed for discussion
at the next meeting.
There being no further business the meeting was adjourned.
Minutes submitted by John Rynearson
