Action Items:
Who When What
---------- -------------- --------
1. All asap Send a brief e-mail describing your Point
Of View on the charter and scope of DC-WG
to the reflector
2. All 4/14 Review the constraint dictionary
3. Enrico 4/14 Send out presentation on constraint
transformations
4. Greg 4/14 Check on the Ambit constraint donation
- still ok to use?
- up to date?
- ok to post on the web site?
4. Mark, Ravi 4/14 Prepare an outline of the overall
architecture for the standards document
Next Meeting:
The next meeting will be a teleconference on Wednesday, 4/15,
from 9-11 PST.
Details:
1. Charter/scope discussion
We didn't discuss the POVs as planned, because Jin had
only received one POV so far.
2. Constraint dictionary discussion
We discussed this briefly; not everyone had a chance
to review it prior to the meeting.
Jin went through his presentation on a conceptual model
for constraints.
Some topics which need to be considered in developing
the standard:
- Verification strategy/validation procedure for each
constraint
- Consistency checking between constraints
- Confidence level
- Precedence
- Logical versus physical relationships
3. Review of VSI requirements list (attached)
We went through the list without much discussion.
An important point was the distinction between
constraints (which describe how an IP block should be
implemented) and assertions (which describe restrictions
on how an IP block may be used).
4. Review of GCL Table of Contents (attached),
status update on GCL
The quick summary on GCL is that it was about 80%
complete for timing. The main thing which was missing
was a consistent description of the macros/operators to be
used in identifying design objects.
5. Status update on Ambit constraint language
donation
Greg indicated that he thought that the Ambit
donation to SC-WG could probably be used by DC-WG,
that it would probably be ok to post it on the DC-WG
web site, and that there might have been some changes
to the constraint language since the donation.
6. Short term plan for developing the
constraint dictionary for timing constraints
We didn't reach any conclusions on this; we probably
have to complete the definition of the charter and
scope first.
News:
The DC-WG e-mail reflector was converted to use Majordomo,
which is a program specifically designed for managing mailing
lists. The e-mail address is still dcwg@vhdl.org.
Thanks,
Mark
