--------------------------------------------------------------------------------
Opens:
- Upcoming meetings on January 22nd and 29th are cancelled. January 29th is the
week of DesignCon. The group decided that the January 22nd meeting should be
cancelled so the Editorial Task Group can use the time slot if necessary for
final work on IBIS 7.0. (see below)
- Bob asked that anyone planning on attending the DesignCon IBIS Summit register
soon. He asked anyone planning on presenting to submit a proposal to him by
Friday, January 18th.
-------------
Review of ARs:
- Randy to investigate if/why/how a clock waveform input might be used.
- In progress. Justin's presentation at the IBIS Summit will touch on this.
- Michael M. to investigate if/why/how a clock waveform input might be used.
- In progress.
- Michael M. to check with IP experts on whether DC_Offset is useful for Tx.
- In progress.

meeting. Walter moved to approve the minutes. Bob seconded the motion.
There were no objections.

New Discussion:
DC_Offset BIRD197.2:
After Walter sent out BIRD197.2 draft 1, Randy had replied with a draft that
addressed some editorial issues. The group agreed with Randy's changes and
proceeded with his draft version as the basis for the following changes.
Bob noted that the text in the Required: and Direction: fields should not be
italicized. Bob noted that the text in the Required: field should say it is
illegal before "7.0" not "7.x".
Arpad asked for the Example's Value entry to be changed from .5 to 0.5.
Arpad suggested we improve the wording of the sentence:
"DC_Offset should be the same as the average of the step response beginning and
end voltages."
The group agreed on:
"DC_Offset should be the same as the average of the step response initial and
final voltages."
Walter moved to submit the version with these modifications to the Open Forum.
Bob seconded. There were no objections.
Upcoming meetings:
Walter noted that there is no meeting on the 29th because of DesignCon. Walter
suggested that we might cancel the ATM meeting on the 22nd as well. This would
allow the Editorial task group to use the time slot for last minute work on IBIS
7.0 if necessary. Arpad agreed and noted that he was willing to cancel the
meeting on the 22nd if people expected to be busy with DesignCon preparations
and IBIS 7.0. Michael M. noted that Editorial was meeting Wednesday and Friday
of this week, and might use the ATM timeslot on the 22nd for mop up work if
required. Arpad cancelled the ATM meetings on the 22nd and 29th.
Walter suggested that we plan to formally introduce IBIS 7.0 and the DesignCon
Summit, though it was too late to meet the earlier goal of introducing it in
time to be voted on at the Summit. Michael M. said the schedule would likely
align nicely with the goal of introducing IBIS 7.0 at the DesignCon Summit.
Walter noted that there will be a panel discussion on IBIS AMI modeling at 3:45
on Thursday at DesignCon. Walter, Michael M., Justin, and others will be on
the panel.
- Walter: Motion to adjourn.
- Michael M.: Second.
- Arpad: Thank you all for joining.
AR: Randy to submit BIRD197.2 to the Open Forum.
