New Discussion:

Interconnect Task Group report:
- Arpad: There was no meeting

Arpad: Should we discuss the new repeater BIRD while Fangyi and Mahbubul
are both here?
- Mahbubul: It would be better to have time to prepare
  - An update could be sent ahead of next week
- Ambrish: Is this BIRD different from what we have?
- Fangyi: It is a new BIRD
- Arpad congratulated Fangyi on his EPEP best paper award

AR: Fangyi and Mahbubul send presentation to Mike for posting

BIRD 121.2:
- Arpad showed BIRD 121.2 draft 9:
- Radek: It may be missing part of the end
- Arpad: I will check
- Arpad: Parts of "Supporting_Files" are under Definition and other parts
  under Usage Rules.
- John: The directory of the IBIS file is ruled out for Supporting_Files?
- Arpad: That was not intended
- Walter: That sentence was added to prevent adding unknown files
- Arpad: You don't have to use dot, the files can be added by name.
- John: Not sure dot should be prohibited
- Arpad: It could be dot slash
- Ambrish: There could be tons of files there
- Mike: The IBIS and AMI files would have to not be double copied
- Arpad: Should wildcards allowed?
- Mike: That might make it too easy to copy unintended files
  - It would be best for the parameter to list all files explicitly
- Bob: Should the parser disallow asterisk?
- Radek: There could be cross OS issues
- Arpad: If a model is for one OS it should be safe to use a wildcard
- Mike: The rules for Perl globbing are platform independent
- Walter: We should keep it simple
  - Either say nothing or disallow wildcards
- Arpad: It would be better to disallow
- Arpad added a clause prohibiting wildcards
- Ambrish: The characters are actually allowed in file names
- Mike: We might say "there is no expectation of wildcard expansion"
- A sentence was formulated

- Bob: Is the sentence disallowing "." sufficient?
- John: A directory could be ".mydir"
- Bob: Should we exclude names beginning with '..'?
- Walter: The intent was to support current directory and below
- Ambrish: How does the model maker know what is around the directory?
- John: These files might be somewhere down a directory tree of files
- Ambrish: The AMI file is supposed to be at the top
- Arpad: We could change the language to disallow copying the full
  DLL_Path directory
- John: We can make it explicit that files must be same directory or below
- Arpad: Matlab might require files that are up and over
- Walter: Environment variables can be used for that
  - We could specify the names of those
- Ambrish: That is OS specific
- Mike: Is it clear that the files have to be copied to the same tree structure?
- Arpad: There is a sentence covering that
- Walter: This is an issue for all of IBIS
  - Every IBIS file has an implicit list of supporting files
  - It is assumed that they are in the same directory
- Arpad: This file will be posted for review
  - Hopefully we can vote on it next week

AR: Arpad send updated BIRD 121.2 to Mike for posting
