-----------------------MINUTES ---------------------------
Mike LaBonte conducted the meeting.
Call for opens and IBIS related patent disclosures:
- None
AR Review:
- Mike ask Lance if he can repeat his correlation presentation
- Done
- Lance has agreed, but can not join us today
- Mike check on IEEE FSV status
- No reply yet from Bruce Archambeault
- Bob: It is not very useful to us
- The tool doesn't work well
- The bucketing is arbitrary
- It is hard to relate numeric results to the visual
- It is not for us to promote FSV or create tools for it
- Vendors might do this, and they will promote it
- We agreed to consider this AR closed
- Mike ask Anders about his level of interest in External Test
- Anders is interested but his time is very limited
New items:
Mike: Our expressed priorities:
- Mike: Correlation is high on my list
- Eckhard has said the AMI checklist is important
- Anders is interested in external test
- Bob: Lance also likes external test
- I also like the checklist
Bob described IBIS parser changes:
- Bob: There are now at least 30 parser test cases
- Most of the changes are in AMI
- IBIS 5.1 is not yet voted, but the parser is mostly ready
- Mike: Will there be another 5.0 parser?
- Bob: No
- We will handle deprecation more rigorously from now on
- For 5.1 (AMI_Version x) is required and must be first
- There are no 5.1 models yet
- Omitting AMI_version implies a IBIS 5.0 model
- Mike: Older tools should be able to ignore (AMI_version 5.0)
- Bob: The parser will call that an error
- BUG 131 will be fixed
- This is about Table type in Reserved_Parameters
- The bug report itself has an error
- There are some rules about order of items
- AMI_version has to be first
- Mike: There should be no order requirements for AMI syntax
- Bob: Also Reserved_Parameters has to be first in 5.1
- Mike: It's easy to read in LISP-like files and check context after that
- Bob: For example you need to know the Labels before read a table
- Mike: A summit presentation on how to use parser code would good
- Snippets of code would have to be shown
- It might be interesting, and somewhat a sales pitch
- Bob: We would have to find someone who knows the code well
- It might be too technical for a summit
- We have added error code numbers but that adds complexity
- Mike: An application developer should be able to ignore the checker part
- IBISCHK should be written as a example parser application
- Currently it is more integrated than that
- Bob: The checker is very exhaustive
- The code is C, not C++
- Lex and yacc may have been used
- This might not be a good topic for an Asia summit
- Only Fujitsu might have bought the code there
Mike: How can be make progress on the AMI checklist?
- Eckhard: I presented on this in Naples
- Only about a two page checklist is needed
- Short descriptions should be on the pages
- It could be similar to Greg's list, which was too close to Opal
- Mike: The one line descriptions on Greg's list were hard to understand
- Eckhard: Good, simple checks can be described in two lines
- Bob: Eckhard could repeat the Naples presentation
Next meetings:
- Next meetings Sep 4 and Sep 18
- Meeting ended at 12:02 ET
