      6/14/95    Birds of the Feather meeting at DAC
      6/15/95    General session meeting at DAC 1:00 - 5:00 p.m.
      7/7/95    (916) 356-9999    _______ 
 
 All meetings are 8:00 AM to 10:00 AM Pacific Time.  We try to have agendas out 
 7 days before each open forum and meeting minutes out within 7 days after.  
 When you call into the meeting, ask for the IBIS Open Forum hosted by Will 
 Hobbs and give the reservation number.
 
 NOTE: "AR" = Action Required.
 
 -------------------------------- MINUTES -------------------------------------
 
 CHECK-IN, INTROS, ANNOUNCEMENTS, TREASURE'S REPORT
 There were no corrections made to last month's minutes.
 There were no new participants.  

 NEW AGENDA ITEMS: 
 None.

 PRESS UPDATES: 
 Electronic Design April 17 and May 1 issues have articles referencing IBIS.
 
 Derrick received over 30 new requests for additions to the IBIS reflector 
 after Jon Powell advertised the IBIS open forum while answering a question 
 from someone in Germany regarding the SI mail list.  We now have 185 
 interested persons on the reflector.

 NEW MODELS AVAILABLE:
 National sent a "SuperI/O" model to Michael for posting.  [Update: it is now 
 posted to vhdl.org.]

 EIA IBIS MEMBERSHIP UPDATE:
 We now have 16 paid members (indicated in the participant list above).

 PROGRESS TOWARD ENLISTING NEW IC VENDORS
 Many of the IBIS members are IC vendors.  We decided to remove this as a 
 regular meeting topic.

 GOLDEN PARSER 2.1 STATUS
 Beta 5 and Beta 6 were dispersed.  Bob Ross went through the test matrix and 
 found four issues in the Beta 6 parser:  
 
 1. The parser crashes in certain conditions like invalid pin counts.
 
 2. On banded matrix, the parser and spec agree, but ignore symmetry.  It 
    confuses banded and triangular matrix forms.  This needs a BIRD.
 
 AR Bob -- Post your banded matrix correction as BIRD29.
 
 AR Bob -- Work with Ron and Paul to correct these in the parser.
 
 3. Sparse matrix problem with alphanumerics (a fundamental problem for PGAs) 
 gives wrong results.
 
 4. Correlation between pin numbers in .ibs files and those in the .pkg file.  
 Bob posted a test case that demonstrates this problem.
 
 Bob feels the parser needs another spin before we release it, but it is 
 getting very close.  We discussed treating Paul and Ron fairly through extra 
 compensation.
 
 AR Will -- Contact Paul and Ron.  Negotiate a fair compensation for their 
 additional work.
 
 Arpad and Bob have checked some of the case sensitivity changes, and it seems 
 to function under Windows, DOS, and UNIX.
 
 By consensus, we decided to roll all pending BIRDs into the ballot-review 
 process.  We also agreed that any changes proposed through the ballot process 
 will be reviewed via the BIRD process.

 SPEC BALLOTT STATUS
 After some confusion, the IBIS spec is out for EIA ballot.  IBIS spec ballots 
 went out to the general EIA mailing list last week, mailings to the IBIS 
 roster list were sent this week.  

 PLANS FOR IBIS MEETING AT DAC (JUNE 2ND - 16TH)
 We will have a face-to-face meeting at DAC to elect officers and conduct other 
 business Thurs. 6/15/95, 1:00 pm to 5:00 pm, Marriott Hotel, tentatively 
 "Pacific 1" room (check the hotel register for confirmation).
 
 Topics:
   Election of officers
   Status of balloting
   Support of MCMs and SIMMs (if we have time)
   Package Issues (if we have time)
 
 AR Will -- Send Jon your "history of IBIS" foils.
 
 [Update: Patty Rusher will attend the face-to-face.]
 
 Placards.  Jon had 40 placards made.  2,000 EDN article reprints have been 
 ordered and will be available at the EIA booth.

 REV 2.1 UPDATES
 o S2IBIS 2.1  Bob Ross reported that very little has occurred.
 o Cookbook    Bob has plans for some submissions.
 o Overview    No discussion.

 BIRD 26 - TAB CHARACTERS DISCOURAGED IN .IBS FILES
 Voted and approved unanimously (8 members voting).

 BIRD 27 - NEW KEYWORD FOR DIFFERENTIAL I/O
 Bob Ward explained his BIRD.  TI has a chip that switches a lot of 
 differential pairs.  This BIRD removes redundancy by adding keyword to 
 override the default differential threshold V_diff value (currently 200 mV) 
 and make it the subsequent default value instead of having to repeatedly 
 override the default.  Bob Ross pointed out that the BIRD would not result in 
 smaller files, and he made some suggested enhancements to the BIRD to 
 eliminate columns and save data.  We will continue this discussion after DAC.
 
 AR Bob Ross -- Send your ideas for altering BIRD27 to Bob Ward 
 ([email-masked]).

 BIRD 28 - PACKAGE MODEL EXTENSION
 Stephen led a lively discussion on this Bird.  Stephen has made changes 
 suggested by various people, notably Kellee Crisafulli.  Lots of discussion, 
 sorting out how this BIRD addresses relatively simple packages and is not 
 intended to address SIMMs and MCMs.  There is a lot of interest in MCM and 
 SIMM support, so the question is, should we create a format to describe SIMMs 
 and MCMs, and if so, does this Bird become redundant?  We will continue to 
 discuss it over the reflector.
 
 NOTE: This BIRD does not currently address MCMs.

 SUPPORT OF MCMS AND SIMMS?  IF YES, HOW?
 Concepts for handling MCMs were tossed around.  Anyone is welcome to post EGG 
 proposals for handling MCMs.
 
 Mike Ventham pointed out that adding more scope to the spec can make it more 
 complicated/intimidating for prospective model writers.  We need to better 
 communicate what is and is not required
