New ARs:


Discussion:
a. (BUG245)_dratf1 - Pending BUG regarding Platform in AMI
   The group reviewed the initial work of this bug report and added some 
   details from previous emails discussing this message.
   Bob noted that if this message should be a numbered message then we should 
   also make all other error and warning messages to have numbers.
   Bob reminded the group that Mike LaBonte delivered a presentation about how 
   the parser checks executable AMI models some years ago when the parser was 
   enhanced to check the executables.

b. BUG243_draft1 - compiler warnings
   Graham Kus Mathworks, etc. Make File Warning messages during architecture 
   compile with:
   "<file name> warning: variable '<variable name>' set but not used 
   [-Wunused-but-set-variable]. Michael Schaeder may provide some feedback 
   concerning gcc compilation. Curtis Clark’s suggestion. Bob get direct input 
   from Atul. Note, Linux and Windows messages are different.
   Bob showed his first draft of the bug report. He included those who 
   provided input on this topic as reporters of the bug. The bug report 
   includes various email messages from the reporters. The report also 
   includes feedback from Atul with some guidelines on how we should specify 
   which warnings should be dealt with. Different compilers on different OS 
   generate different warnings depending on the flags given to the compilers. 
   Bob will state that the warnings should be corrected as much as possible. 
   Bob will work on the report to specify which compilers to check and the 
   specific compiler flags to use in checking.

c. Quality Specification and checklist power aware discussion.
   Mic Schaeder checked [Merged Pin] check and it is working properly.
   Weston sent a new draft of the specification document to the task group 
   email list for review. Arpad Muranyi suggested during the IBIS Open Forum 
   meeting last Friday that he might have some details to add regarding using 
   Touchstone models in EMD files.
   There was no other feedback nor discussion on this topic this week.

d. BUG244_draft1 - Randy Wolff’s write-up based on Arpad Muranyi’s original 
   concern about IBIS Ver in IBS file referenced from an EMD file discussed on 
   May 2, 2023.
   Bob showed the latest draft of the bug report. The bug report includes the 
   text of the EMD and IBS files for the test case. The group discussed 
   possible changes to the text of error message E5810 to indicate that the 
   IBS file was checked for IBIS v7.0 compatibility.


Tabled topics (no discussion without motion):
a.	Secure Development Lifecycle (SDL) investigation (Security fixes 
    continuation), (TSCHK2, BUG6)
b.	TSCHK2 V2.02 BUG5 and BUG6 (implementation on hold)


Weston moved to adjourn. Randy seconded. Without objection the meeting ended.

Meeting ended: 1:12 pm ET
