Call for patent disclosure:

No one declared a patent.

Opens:

Review of ARs:

- SiSoft will propose a new reserved_parameter keyword table
  - TBD

- Ambrish: Send updated AMI BIRD proposal
  - Done

- Write parameter passing syntax proposal for a possible BIRD
  a) Propose a parameter passing syntax for AMI models
  b) IBIS spec should allow parameter value assignment for
     *-AMS using a syntax that is consistent with the
     parameter passing syntax of the AMI models
  c) Allow parameter passing for SPICE [External ...] also?
     - Berkeley SPICE does not handle paraeters at all.
     - Walter proposed handling this with a preprocessor

- Ian: send relevant papers on related IEEE work
  - TBD

- Arpad: Review the new macro library files.
  - TBD

We affirmed that the "electrically isolated" AR has been done.

-------------
New Discussion:

- Cadence AMI toolkit status:
  - Hemant should be distributing it by the end of the week

- Discussion of BIRD proposal:
  - Ambrish: Should it be TXT or PDF?
    - Bob: The BIRD should be TXT until the IBIS spec is PDF.
    - Michael M.: We can send both TXT and PDF.
  - The BIRD will be submitted by email, can be any time.
    - Michael M.: It must be available 2 weeks before a vote takes place.
    - Michael M.: BIRDs require a 3 meeting comment period.
    - Bob: Actually only standard changes require this.
      - BIRDs can be revised until voted into a standard.
      - Subsequent BIRDs might "touch it" and force changes.
  - Michael M.:
    - A change like parameter passing might be a big change.
    - There may be a lot of discussion.
    - We must consider all of the things that should be in IBIS 5.0.
  - Bob: other things will be in IBIS 5.0:
    - ICM
    - BIRD 98 (gate modulation)
    - BIRD 95 (power delivery)
  - Ambrish: It sounds like it may take a year before IBIS 5.0 comes out
    - Michael M.: EDA vendors can implement any time
  - Bob: Does the proposal ask for a new section following section 6?
    - Changes for [External Circuit] etc. are confined to a section 6a.
    - Trying to disperse the language may trigger editorial discussions.
    - Spreading it out would require forward links.
    - A new section 6b would be better.
  - Ambrish: Maybe we could use [External Model] instead of [Algorithmic Model]
    - Bob: The syntax is different.
    - Arpad: We could add a subparameter to [External Model].
  - We can send this BIRD soon and discuss at the next open forum Sep 21.
  - Arpad will send final BIRD to Michael M. by Sep 7.
  - Bob: The proposal should have people names, not just companies.

AR: Ambrish send updated BIRD 1.2 version to group
AR: All review BIRD proposal before this Friday

There will be a meeting next week, although some members will be travelling.

Next meeting: 4 Sep 2007 12:00pm PT
