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

Call for opens and patent disclosures:

- No one declared a patent.

- Bob: Pavani may be returning from leave soon

- Mike: We should skip Dec 29 but meet on Dec 22
  - We can meet Jan 5

AR Review:

- Moshiul rework IQ checklist for IQ 2.0
  - Started work but was pulled away

New items:

Mike showed the Accuracy Handbook:
- Bob: This is a good document
  - A good supplement to the cookbook
  - The question again is "How to designate levels?"
  - We can do better correlation
  - We can't tell vendors what to do
- Section header level review
  - 1.1 to 1.4 are OK
  - 2.1
   - Anders: Do we want to address accuracy or correlation?
   - Bob: They are intertwined
   - Mike: That is a section 3 discussion
   - Mike: Probably want to add to 2.1
     - 2.1.3 differential drivers
  - Bob:
    - 2.1.1 Simple CMOS drivers
    - 2.1.2 Differential
    - 2.1.3 De-emphasis modes
  - Mike: Some of this is about making models
    - Maybe it could move to the cookbook
    - then add correlation here
  - Bob: We don't want to have 3 projects at once
  - Mike: Is 2.2 needed?
  - Bob: This was all of IBIS when the Accuracy Handbook was written
  - Mike: There may not be many more keywords to add
    - The Accuracy Handbook is all about drivers
    - [Receiver Thresholds] would not apply
  - Bob: We would add [Diff Pin] and [Driver Schedule]
  - Moshiul: [Submodel] too
  - Mike: I could create a skeleton header
    - Also someone could update Table 1
- 3
  - Mike: This could go in the cookbook
  - Bob: Not to be belabored or expanded
- 3.2: Measurement Techniques
  - Mike: It covers the 3 things we measure
    - 3.24: Add BIRD95 keywords
  - Bob: The currents at ground terminals
  - Mike: The scope should clarify that this is not AMI
  - Bob: It's not about the package either
  - Mike: Could this be about packages?
  - Bob: Yes
    - That is a separate discussion, with field solvers, etc.
  - Mike: The title is "I/O Buffer Accuracy Handbook"
- 3.3 IV Curves
  - Mike: Section 3.3.1 is just circuit pictures
    - The 2 circuits in 3.3.1 look almost alike
    - Maybe we don't need these
  - Bob: Maybe we could pull back on this
- 3.4 Test Load Waveforms
  - Mike: Is this section about correlation?
  - Anders: Yes but it doesn't say how
  - Mike: This should be in [Test Load] language
  - Anders: That may be more helpful for simulation correlation
- 3.5 Capacitance
  - Mike: There are at least 4 ways to measure capacitance
  - Bob: This shows the TDR method
  - Mike: This could have a more complete discussion
  - Anders: It is not clear if 3.4 and 3.5 are for extraction or correlation
  - Mike: 3.2 is "Measurement Techniques"
    - It could be for either
    - 3.4.1 and 3.4.2 are for extraction
    - 3.4.3 on are for correlation

Meeting ended at 12:08 PM Eastern Time.
