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

AR Review:

- Roy will contact David to continue collaborating on correlation.
  Done. David will give feedback on Roy's by Thu

- Bob and Moshiul will collaborate to rewrite section 2.1
  Done, uploaded to web site

New items:

How do we know which IQ checks are covered by IBISCHK?
- David: Makes checking an IBIS file go slower.
- Bob: IQ is not a way to rewrite the IBIS spec.
- Should be a column in the checklist spreadsheet.
- example:
  4.1.3.	{LEVEL 2}  [Model] C_comp is reasonable
  C_comp must be defined, positive and less than 20pF.
- We established some time ago that this matches what IBISCHK does.
- If we document IBISCHK coverage, would want to give required version.
  - Spreadsheet column should have version numbers.
- IBISCHK does not have a 20pF limit, it is 1nF
- IQ should match what IBISCHK does
- No need for 4.1.3 if 4.1.4 is required for LEVEL 2

AR: Mike add IBISCHK info back into IQ spec & checklist

AR: Kim remove 4.1.3 and add to 4.1.4, send to Mike

Review of new IQ 2.1 section:
- We decided to review individually, outside the meeting
- Some confusion over the 1.1h document uploaded to the IQ archive.
  - Bob recalls the paragraph agreed on by him and Moshiul looking different.

AR: Bob check on draft 1.1h doc versions

AR: All review IQ 2.1 and comment by email

Some discussion about when to use "X"

Parallel editing efforts
- For the first time, we have edits by more than one person in progress
- Mike will remain the archivist
- Smaller edits can be sent to Mike as fragments

Should we renumber?
- Mike suggested that it may be best to leave IQ check numbers unchanged
  after deleting checks.
- This would leave a gap in the numbering.
  - An alternative is to leave the deleted check but mark it obsolete
- No decision on this, deferred to the next meeting.
