Next Meeting:
The next meeting will be a teleconference on Tuesday, 6/9/98,
from 9-11 PDT. Note the change of day.
Action Items:
Who When What
---------- -------------- --------
1. Mark 6/5 Send a skeleton version of the taxonomy
document listing all of the timing
constraints
to the reflector
2. Mark 6/9 Fix broken links on the web site
3. Mark 6/9 Investigate RAIL and get documentation on it
4. Mark 6/9 First draft of taxonomy for clocking
5. Greg 6/9 First draft of taxonomy for exceptions
6. Steve 6/9 First draft of taxonomy for parasitics
boundary conditions
7. Jin 6/9 First draft of taxonomy for timing boundary
conditions
Details:
1. Charter/scope discussion
We reviewed the revised document from Jin
- Constraint dictionary should be changed to constraint
taxonomy
We agreed that we should investigate RAIL.
2. Constraint dictionary discussion
We came up with several additional columns
- Range restrictions
- Dependencies / exclusivity of parameters
- Verification procedure
We reviewed the GCL table of contents, which lists
a number of different types of constraints. Additional
timing/clocking constraints we identified are
- modes
- clock delays
- tag-based constraints, where a tag (label) is used
to distinguish between arrival times associated with
different sources
We discussed how to make progress in defining the
taxonomy document, and agreed to partition the work
into several categories
- Parasitics boundary conditions
- Timing boundary conditions
- Exceptions
- Clocking
- Modes/constants
3. We also talked about having a face-to-face meeting at
DAC. Due to logistical difficulties, this wasn't possible
to set up. We should meet at ICCAD at least.
Thanks,
Mark
