2. Steve 2/16 Present changes to parasitics portion of the taxonomy.
Open action items:
Who When What
---------- ------ --------
1. Steve, Jim, 2/2 Discuss PVT-dependent constraints and relationship
Greg -> 2/16 to conceptual model
2. Jim 1/19 Add operating conditions to the taxonomy
-> 2/16
3. Jim 1/19 Investigate whether IBM could provide the
-> 2/16 Einstimer educational material as a reference
Closed action items:
Who When What
---------- ------ --------
1. Jim 2/2 Prune the list of IBM patents that might cover
the DC-WG work
2. Greg 2/2 Investigate the semantics of the BuildGates
set_port_capacitance_limit command
3. Greg, Steve 2/2 Talk about reconciling the parasitics portion
of the taxonomy with the BuildGates strawman
4. Mark 2/2 Follow up on Tau '99
5. Mark, Greg 2/2 Come up with a proposal for the semantics of
how source latency and jitter, common ambiguity,
common jitter, and inter-clock uncertainty relate
Next Meeting:
The next meeting will be a teleconference on Tuesday, 2/16/99,
from 9-11 am PDT.
Details:
1. Prune the list of IBM patents that might cover the DC-WG work
Jim sent e-mail regarding one patent. US patent #: 5210700
What do we do with this information?
2. Investigate the semantics of the BuildGates
set_port_capacitance_limit command
The command set_port_capacitance_limit command in BuildGates, while
worded in the strawman to imply it constrains only the external cap,
does limit the cap on the entire net, internally as well as the contributions
externally.
3. Talk about reconciling the parasitics portion of the taxonomy
with the BuildGates strawman
Completed. Steve and Greg met. Steve's absence at the meeting (he called
in 10 minutes after we finished :-( ) prevented us from reviewing these
changes.
4. Follow up on Tau '99
Subject: DC-WG and Tau
Date: Mon, 1 Feb 1999 16:43:38 -0800
From: mhahn (Mark Hahn)
To: gschulte
Greg,
Here's status on the TAU-99 action item I had. I got a copy
of the workshop schedule, and there isn't really any time
available to have a side meeting at the workshop itself.
The workshop falls on Monday and Tuesday, March 8-9, which
is on a DC-WG/SLDL joint working group week. I propose that we
plan for a combination face to face meeting and teleconference
on Wednesday morning, March 10th. The focus of the meeting
would be DAC planning.
Mark
5. Come up with a proposal for the semantics of how source latency
and jitter, common ambiguity, common jitter, and inter-clock
uncertainty relate
In revision 0.6 of the taxonomy.

We reviewed the document and had some questions for Mark. Overall,
the clock structures looked complete.
