Call for patent disclosure:

No one declared a patent.

Opens:

Donald Telian asked to discuss use of materials presented

-------------
Review of ARs:

- Todd clarify "electrically isolated" in BIRD
  - Maybe at the end of the summer
  - TBD

- Michael Mirmak get specific data on the non-linear behavior problem
  - Long term, drop from AR list

- Arpad: Write parameter passing syntax proposal for a possible BIRD
  - Question about if this is for just the API or for IBIS SPICE extensions
  - Michael M: this might be split up
  - Michael M asked Arpad to clarify the AR text
  - TBD

- Arpad clarify text of "parameter passing syntax" AR
  - TBD

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

- Hemant will publish an open source reference model by Jul 17
  - Ambrish will present a model and program today
  - TBD

- Ian send relevant papers on related IEEE work
  - TBD

- Ambrish send presentation to Mike
  - Done

- Todd send draft Asia summit presentation
  - Done

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

AMI tools cross testing progress:
- SiSoft and Cadence swapped model source
- Both sides debugging problems
- Mike S. looked at code sent by Ambrish
- Not done yet
- Should have interoperability by the end of this week.

Todd gave his proposed Asian summit presentation:
- Page 1:
  - Title page typo will be fixed
- Page 2:
  - Need to indicate that this flow is not where people are now
  - Ian plans to show 2 step process
  - Single step process brings a performance hit
- Page 4:
  - Doug: Stateye is not really separate from Matlab
  - Michael M: may be legal restrictions on mentioning Matlab
- Page 5:
  - Discussion of digital vs. analog equalization modeling
- Page 7:
  - Michael M: Some characterization is done without existing IBIS
  - Michael M: Check with companies on exact names
- Page 10:
  - Michael M: Might run into a time limit, may want to remove this one
  - Previous slide has some of the same content
- Page 12:
  - Donald: Is there a connection between 2 step process and Init/GetWave?
  - Todd: No, Init and GetWave are essentially steps 2a and 2b
- Page 13:
  - Originally submitted by Cadence/IBM
  - Radek: should Cadence and SiSoft be mentioned?
  - Todd: this is freely distributable, public domain
  - Bob: Will there be a public record of who gets the kits?
  - SiSoft and cadence willing to remove company names from presentation
  - Todd: copyright allows people to redistribute freely anyway
  - Todd: Not many people have asked for the software so far
- Page 14:
  - Arpad: Change title to reference DAC
    - Term "as of" may not be clear to non-English speakers
  - Arpad: Should this mention the parameter passing BIRD?
  - Todd: Can we simply not mention a date?
- Bob: Need separate presentations for the 2 conferences
- Will not be posted on the ibis-atm website yet

AR: Todd update Asia summit presentation

Donald Telian asked when software would be ready:
- Todd: Want to
  - Get feedback over the summer
  - Incorporate feedback in Sept
  - Present to IBIS committee
- Donald: Some people might want to see the IBIS early
- Todd: Demonstrating success will help the approval process
- Michael M: Targeted for IBIS 5.0
  - Next June would be optimistic
- BIRD 74 was approved but missed IBIS 4.2
- Todd: Cadence has a new proposal that would simplify the IBIS file
  - Changes parameter declarations
  - Changes to IBIS would be minimal
  - EDA vendors still discussing

Donald Telian asked if the work can be used by others:
- Todd: It's all public
- Michael M: Please include appropriate credit

Next meeting: 14 Aug 2007 12:00pm PT
