Review of previous meeting minutes:
Minutes from the 21 JUN 2022 meeting were reviewed. Lance Wang moved to 
approve the minutes. Bob Ross seconded. Without objection the minutes were 
approved.


AR review:
 - Bob submitted draft5 of IBIS V7.2.0 parser contract to Jose Godoy (SAE ITC) 
   for review.
 - Weston has created a working document to discuss quality checklist updates. 
   This will now be an item to discuss on the weekly agenda.
 - Bob requested a description of code changes in bug5 (Touchstone) from Mic 
   Schaeder who submitted the bug and edited source files.


New ARs:
 - Bob will ask Mike Labonte if he is willing to compile the V2.0.2 tschk2 for
   Windows, Linux, and Unix.


NEW ITEMS:
Bob asked if we should a) ask Mic to provide the various compiled programs of
tschk2 for windows, Linux, and Unix, b) if we should ask some IBIS member to
do it, c) work with Atul (parser developer) to work on tschk2, or d) do 
nothing for now until we have more bugs to fix in a new release of the 
utility. Bob will start by asking Mike LaBonte, since he has done this in the 
past and might have the appropriate programming environment already configured.

The task group continued the discussion of quality items specifically 
regarding the Composite Current tables. The current (I-T) tables must be 
aligned in time with the rising and falling (V-T) waveforms. If a model author 
removes initial delay in V-T tables, the same delay must be removed from I-T 
tables and they might unknowingly remove some signficant data from the I-T 
tables. Is there a way to programmatically check for this error? Bob commented 
that there were a couple of presentations at recent IBIS summit meetings to 
show improved methods of using the composite current information in 
simulations.


Tabled topics (no discussion without motion):
  - IBISCHK security fixes

Lance moved to adjourn. Bob seconded. Without objection the meeting ended.

Meeting ended: 12:48 ET
