Review of ARs:

  - Done, draft 8

- Mike check BIRD 121.2 draft 6 for correct numbering inside
  - Fixed

- Walter & Ambrish clean up BIRD 150
  - In progress

- Walter update BIRD 123
  - Walter: Radek planned to check the clock PDF section
  - Radek: In 5.0 we had the RjDj option, should be included here
  - Walter's motion to submit the BIRD was delayed

-------------
New Discussion:

- Interconnect task group report:
- Walter: Last week was mostly a presentation by me
  - There has been an email thread about what can be in a package
  - We might make part of the model dependent of the die, part on the package

Arpad showed BIRD 121.2 draft 8:
- Arpad: Bob had asked for a change to the description field
  - Added clarification "current working directory of DLL process"
- Ambrish: The description needs to be fixed to "where the DLL is located"
- Arpad made the change
- John: We should be clear that it is a process running the DLL
- Bob: Do we have to spell out which Supporting_Files are files and directories?
- Mike: The tool can figure that out easily
- Arpad: We should be clear about forward and backward slashes
- Radek: It does not say if the path 
- John: The contents of directories should be copied
- Ambrish: That should be documented
- Bob: We need to say if paths are allowed
- Walter: We would not allow paths to items in subdirectories
- Radek: We should allow that
- Arpad: We should say that a subdirectory item in a copied directory just copies the directory

AR: Walter add slash and directory clarifications to BIRD 121.2

Walter motioned to submit the BIRD 123 update in current form to Open Forum:
- Arpad: There have been no recent changes
- Radek seconded the motion
- Arpad showed the BIRD
- Ambrish: Is numeric literal correct?
- Bob: Default is optional
- No one objected to the motion

AR: Arpad send BIRD 123 draft 5 to Open Forum

BIRD 150 was tabled

Arpad: Fangyi mentioned repeaters
  - We will schedule time for his proposal

Ambrish showed Back-Channel Support BIRD draft 3:
- Ambrish: This is now in the IBIS 5.1 document format
  - It proposes the "Bits" type
  - It has Training and Backchannel_Protocol parameters in the .ami file
  - A number of other parameters are defined for the .bci file
- Bob: The Format of Training_Done is not right
  - It should not have a Default
  - Description has to be a string
- Mike: Is the .bci file written incrementally?
- Ambrish: It is written once
- Walter: It is read-only, supplied with the AMI file
- Bob: Does the .bci file have a version number?
- Ambrish: It could have [BCI Version]
- Walter described IBIS spec update scenarios
  - It probably would be best to have [BCI Version]
- Ambrish: I will add this
- Walter: There are industry standards for backchannel protocol
  - We should have real examples to work with
- Ambrish: There may be issues getting this from an IC vendor
- Alfred: I might be able to create an example
- Radek: We should allow newer .bci files with older .ami files
- Walter: The protocol could specify things only the tool needs to know

Arpad: We should finish the two BIRDs in progress then focus on backchannel
