-----------------------MINUTES ---------------------------
Mike LaBonte conducted the meeting.

AR Review:

- Mike add David's text for 4.2.21, 4.2.23, 4.2.25 to IQ spec
  - TBD

New items:

AR: Mike post Roy's doc in work archive

- Roy suggested that there should be documentation for ibischk
  - Mike, Bob, and Michael Mirmak have made various efforts
  - Access to the source code is limited
  - Bob: at end of year IBIS usually has money to lose

Continued review of IQ specification:

- 5.1.1. {LEVEL 2}  [Model] parameters have correct typ/min/max order
  - We reviewed usage of min/typ/max data in IBIS
    - Bob said that min/typ/max is by process corner for all data except C_comp
      - The min data is slow, max data is fast
      - C_comp min is the lowest value, which admittedly is usually fastest
      - Expected min temperature value is highest for CMOS, lowest for bipolar
    - Kim pointed out that it is difficult to determine slow/fast by looking
      at IV tables
      - Looking at area under IV curves may not be correct
    - David said that package values are in numerical order, and 
    - Bob: package values are not correlated with buffer corner
  - This check should explain the exceptions
  - Kim said the current text of this check is contradictory
  - David said that Hyperlynx takes max [Package] for slow sims
    - But this check is only about model data
  - Moshiul said that IBIS [Temperature] is not really used by simulators

AR: Bob modify 5.1.1 to explain [Temperature] better

Roy prepared a report to IEEE EMC group on IBIS activities
- Covers:
  - ATM
  - IQ (David Banas presentation)
  - ad-hoc Interconnect group, Touchstone 2
  - Mirmak SPICE3 proposal
  - FSV for model accuracy
- Half of the 1000 person conference interested in our area
- They have a TC-10 standards committee working on FSV
  - Interested in working with us
  - 1/3 of their papers would be of interest to ibis-list
- Dr. Albert Rulie, inventor of PEEC method very interested in
  putting an IBIS wrapper around SPICE
- We could put relevant IEEE papers in our work archive
- They talked quite a bit about IBIS

Next meeting:
