Review of previous meeting minutes:
Minutes from the May 3, 2021 meeting were reviewed.  Bob Ross moved to approve the
minutes. Lance Wang  seconded.  Without objection the minutes were approved.


ARs:
- AR: Mike to check latest code for global variable change
  Mike said it was still there. Bob Ross said that was because BUG228 was not yet fixed.
- AR: Weston Beal to prepare presentation on IBIS Quality Specification and checklist
  Weston had not had time to work on this.
- AR: Mike LaBonte to prototype root name checking
  Mike had not had time to work on it more.


NEW ITEMS:

Parser bug reports:
Weston Beal asked if there was an existing testcase for a new [Merged Pins] bug.  Bob Ross
said the source code had test suites, and one of those might be used.  He said we had a
testcase for [Merged Pins].  Weston said he would check and see if there really was a new
bug.


Parser development:
Mike LaBonte asked if Bob Ross would be drafting a requirements specification for a new
IBISCHK 7.1.1 parser.  Bob said he would do that when he found time.  Bob described the
IBISCHK development process.  He said we would pad the development time estimate given to
us.

AR: Bob Ross to draft requirements document for IBISCHK 7.1.1


Future meeting logistics:
Mike LaBonte said he planned to wind down his IBIS involvement, although he did not have a
firm date to withdraw from IBIS Quality activities.  He asked if Weston Beal could
increase his involvement, and if the meeting time might be changed to help with that.  Bob
Ross said he could chair the meetings.  We talked about the level of effort for someone to
take minutes, agreeing that IBIS minutes in general were often much more detailed than
they should be.


IBIS quality checklist:
Mike LaBonte felt it would be good for IBISCHK to optionally produce a checklist file
noting the checks that could be performed manually.  Weston Beal said he had done
something like that, and that would put him in a good position to think about a new
development.  Bob Ross said some automated checks with tolerances could also be helpful.


IBIS press:
Bob Ross recommended the new book by Donald Telian, "Signal Integrity, In Practice: A
Practical Handbook for Hardware, SI, FPGA & Layout Engineers", which discusses among other
things the history of IBIS.


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


Bob Ross moved moved to adjourn. Weston Beal seconded. Without objection the meeting ended.


Meeting ended: 12:42 ET
