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

Call for opens and IBIS related patent disclosures:

- Mike: We could look at AMI BIRDs for their IBIS Quality implications

- Greg: How many of us will be at DesignCON summit?
  - Anders and Bob will be there
  - Eckhard and Mike will not be there

AR Review:

- Mike report on status of External Test BIRD 
  - This is not a BIRD, Anders was asking for the [External Test] proposal
  - Mike sent that to Anders
  - Anders: We should look into this at some point

New items:

Mike showed the spreadsheet of IBISCHK error messages:
- Bob: It is surprising how many error messages we have
  - The comment column was most requested, and the most work
  - I added the Category column
  - We can promote and demote messages Warning <=> Error without number change
- Mike: Surprising that there are codes for internal errors
- Anders: Is this posted online?
- Bob: The best place would be where IBISCHK5 is downloaded
- Mike showed the IBISCHK download pages

AR: Bob upload IBISCHK5 message spreadsheet to web

- Mike: There is no check for duplicate platforms in [Algorithmic Model]
  - You could have multiple models for one platform
- Bob: The EDA tool should treat that as a selector
- Mike: We should ask the ATM group about this
- Bob: We also have a problem with open-ended platform specifiers
  - What if "Linux" is not always spelled that way?
- Mike: We left it that way intentionally
- Bob: I challenge that decision
- Anders: We could define the ones we know, but allow others to be used
- Bob: That could be a BIRD
- Mike: Could it be a 5.1 BIRD?
  - This is just a clarification
- Bob: The 5.1 work load is high
- Mike: The existence of a BIRD might be enough to make a difference

- Mike: The spec allows for multiple lines only for different executables
  - Two lines with the same Platform_Compiler_Bits could have different .ami files
  - What would the EDA tool do?
- No one in the group had seen an occurrence of this type of problem
- Bob: This is a quality issue

Mike showed the BIRD list:
- Bob: BIRD 149 will come up in the ATM meeting today
- Mike: Should we file QUAILs for BIRDs like 115?
- Bob: It performs no meaningful checking as it stands
  - We might drop all checking until we have better checking
  - Budget is an issue
  - Spec quality is also an issue

Next meetings:
- Next meetings Jan 24 and Feb 7

Jan 24 agenda:
- Discuss IBISCHK5 parser expansion for AMI

Meeting ended at 12:07 Eastern Time.
