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

Call for opens and IBIS related patent disclosures:

- No one declared a patent.

AR Review:

- Mike post outline
  - Done, but no announcement

New items:

Bob showed the IBIS Correlation Outline and made updates:
- Mike: Does any part of this not make sense?
- Anders: Why is there not a Simulation section?
- Mike changed Measurement to "Measurement and Simulation"
- Anders: The correlation has to check the same node on both sides
- Moshiul: The correlation setup belongs in section 3
- Anders: Why do we have Receiver Output correlation?
  - We deleted that
- Anders: Input correlation is not that same as others
- Mike: Is die capacitance comparison really correlation?
- Moshiul: This is effective capacitance as seen at the pin
- Anders: What will be our measurement points for that?
- Mike: Maybe we could drop Effective Capacitance correlation
- Anders and Moshiul wanted to keep it

Mike: Should correlation be against actual data in an IBIS file?
- Maybe it should always be against IBIS simulation, not IBIS data
- Moshiul: Some IBIS data should be checked directly
- Mike: I/V curves are extracted and recombined by simulators
  - Doing that and checking correlation could be worthwhile
- Anders: This can be simulator dependent
  - What is the scope of this?
- Anders: We should correlate the IBIS data, not simulators
- Bob: We should not make it a big project
  - The IBIS model is not the only variable
  - Measuring it through parasitics complicates things
- Mike:
  - There are two parts:
    - What to correlate
    - How to measure correlation
  - We should focus on the latter

Bob: We should keep the input section
- The effect of inputs on reflection is significant

Anders: Who would be using this document?
- Mike: IC vendors
- Moshiul: Mostly
- Mike: Maybe our document should have 2 sections:
  - sim-sim correlation
  - sim-data correlation

AR: Bob send updated IBIS Correlation outline to Mike
AR: Mike post updated IBIS Correlation outline to IQ web

Next meeting will be Apr 12

Meeting ended at 12:14 PM Eastern Time.
