Mike LaBonte conducted the meeting.

Call for opens and IBIS related patent disclosures:

- No one declared a patent.

AR Review:

- Anders prepare External Test Load/Data presentation for DesignCon
  - No report (Anders had not yet joined)
  - Bob: There is some room in the agenda
    - We need to know the agenda by Thu Jan 27
    - Reproduction deadline might be Jan 25

New items:

PWL source experiment discussion:
- Mike showed PWL waveforms with 10 digit resolution
  - here are some differences from the source simulation
- Bob: Arpad showed a presentation at one time about an HSPICE issue
  - It may be necessary to go beyond regular float resolution
- Moshiul: The time step has to match
  - Need to set DELMAX

Anders presentation for IBIS summit.
- Anders: The words need to change
- Slide 1 
- Slide 2
  - Mike: The circuit diagram should be darker
    - It would be nice to estimate data size
  - Anders: We need to discuss if there is a limitation on probe points
  - Mike: We could see how many waveforms typical quality reports have
  - Moshiul: What does "limited to a static structure" mean?
  - Anders: Maybe it should be "fixed topology"
  - Mike: "Existing [Test Load]" might be better
  - Anders: We found that we could not get needed probe points for bench data
  - Bob: That limitation might be stated in the spec
  - Anders: Maybe Stimuli should be Stimulus
    - Also should add that larger test data is possible
- Slide 3
- Slide 4
  - This needs a picture
- Slide 5
  - This needs a picture
  - Maybe it should show the ISS terminals
- Anders: There is nothing about diff
- Mike: Maybe slide 2 should mention that
- Bob: We do have some kind of support for that
- Mike showed the IBIS 5.0 spec
- [Test Load] does have differential provisions
- Bob: there is R_diff_far
- Anders: It is not shown in the picture however
- Bob: We will have to work out the probe point syntax
- Anders: The Test load subckt should define the probe points
- Moshiul: Will this change the IQ designation?
- Anders: We added a G designator for golden waveforms
- Mike: What should the title be?
- Anders: [External Test Load/Data] Concepts
- We will review this Jan 25

AR: Anders and Mike finalize IBIS summit presentation

Next meetings:
- Next meetings Jan 25 and Feb 08

Jan 25 agenda:
- Review IBIS summit presentation

Meeting ended at 12:18 Eastern Time.
