Details:
1. Review action items
Jim Engel and Mark sent proposals for the operating conditions
to the reflector.
Bob Dilly sent an item on DC-WG to the ESNUG mailing list, although
this hasn't appeared yet.
We talked again about including wildcards in the DCDL standard,
and there was good support for doing so, to avoid a large increase
in constraint file size as tools read and then write out constraints.
2. Discuss operating conditions proposals
We had a good discussion on this, with general agreement with Mark's
proposal. Supporting back-annotation of instance-specific voltage
and temperature values in DCDL was a question raised in the proposal,
and there was agreement that DCDL should.
There were a few issues that still need to be addressed:
- whether and how to specify a 4 point analysis
(min best case, max best case, min worst case, max worst case)
- whether and how to specify three operating points for
use in generating SDF min:typ:max triplets.
After some discussion, sentiment was leaning towards supporting the
4 point and 3 point specifications in a similar way as described in
the GCF 2.0 draft. Mark took an action item to update the proposal
to address this.
Thanks,
Mark
