 8.  Rev 2.0 Review/Discussion/Approval of pending sections 
 We addressed all Rev 2.0 draft open issues brought up:
 o Bob Ward: Correction to temp range (typ min max):  "NA" is valid 
   for min and max only.
 o Bob Ross: Eliminate the word "usual" from the spec.
 o Bob Ross: Eliminate parameters, sub-parameters from General Syntax 
   Rule #1.
 o Bob Ross: [Component Name] argument can have blank characters.  Add 
   recommendation to not use them.
 o Bob Ward: [End Model Data] keyword is overloaded.  Add an [End Package 
   Model] keyword.
   AR Eric B: Post a note documenting the changes to the package model 
      section of Rev2.0.  [DONE]
 o Move all the various IBIS_CHK program notes to the end, after a "cut" 
   line.
 o Under the [Model] keyword, make a table specifying which sub-params 
   are required/optional.
 o Make the wording on power supply specs consistent.
 o And many more...  (See rev2.0x.txt file being posted by Stephen Peters.)

 AR Stephen: Call Kellee regarding BIRD 8.2 wording.

 9.  BIRD 14/16, New section for [Model] sub-parameters  
 Bob W. feels it is a nice feature, but Bob does not want this BIRD included in 
 the spec. yet.  Until reduction of model size becomes a real issue, he feels 
 this BIRD adds complexity we don't need -- no compelling need now.  Kumar 
 agrees.  This lead into a discussion of the need to discuss pin-centric vs. 
 model-centric IBIS philosophies.

 Consensus was that it is a good idea, but we will table this BIRD until there 
 is a real need and possibly add it in Rev 3.0.

 10. BIRD 15, Clarification on usage of the V/I tables    
 Consensus to let BIRD 15 stay as is in Rev2.0 draft.

 11. Wrap-up, Next Meeting Plans                
 Next meeting is 6/9/94, 8:00 am, at the DAC conference in San Diego.

 AR Kumar: Post IBIS meeting location details to the reflector Loire 
 Supposki (Kumar).  [DONE]

 The next meeting after DAC is 6/24/94.
