Michael Mirmak convened the meeting and took minutes.  No patents were declared. 

During the review of October 18 minutes, the team examined Arpad Muranyi's 
comments over the reflector regarding corrections to 

     "'Arpad noted that his AR regarding research for the phrase "less than allowed" 
     related to noise parameters was still open.'

     I think I was trying to say that I considered my AR done, because I did ask 
     Vladimir [Dmitriev-Zdorov of Siemens EDA], except that he wasn’t able to answer 
     the question, so the question is still open."

Arpad also found two typographical errors:

“Randy Wolff asked whether, regarding normalization for noise parameters whether [sic]
the existence”

“Randy suggesting [sic] ignoring the issue”

Arpad moved to approve the minutes with these changes; Lance Wang seconded.  
The minutes were approved without objection.

During AR review, Michael noted that his ARs regarding Sam Chitwood's inductance loop 
and referencing presentations, plus his AR regarding Pete Pupalaikis's compression
algorithms for network parameters, are still in progress.  

Michael added that he has an AR to ensure Steve Parker is posting relevant documents 
to the IBIS Interconnect Task Group page. [AR]   

All other ARs closed.  

Michael opened the discussion of the Touchstone 2.1 draft.  He summarized
the key changes, including updates to at least one equation and minor
formatting changes to the multiple resistance syntax descriptions.

Arpad asked about updating all the equations.  Michael confirmed that all 
of the equations use a more modern format.  The team made additional 
edits to italicization throughout the document.

Arpad mentioned that it would be nice to announce Touchstone 2.1 at the
upcoming summit meetings.

Michael took an AR to research Gonzalez's book to see if any reference 
to it should be added to the draft, regarding noise parameters. [AR]

Arpad moved to send the Touchstone 2.1 draft for distribution to the
IBIS Open Forum for approval.  As a point of order, Arpad asked about 
when any Gonzalez information would be added.  Michael suggested this
could be done during Open Forum review.  Arpad asked about the copyright
and registered trademark notations.  Michael and Randy noted that they
appeared to be correct, but that the specifics should be reviewed with
SAE ITC legal.

Walter Katz seconded the motion.  The motion was approved without 
objection.  Michael took the AR to send the document to the reflector. [AR]

Arpad will provide an update on pole-residue formats for next time. He
stated that the technical content is complete but the formatting needs 
to be revised. 

Walter added that he believed just one meeting would be necessary to 
decide between the formats.

Arpad moved to adjourn; Bob seconded.  The meeting adjourned. 

The next meeting will be held November 1, 2023.
