You got me thinking, Dave, about "contamination" too.
Something we work at being attentive to here. I'm not
an attorney, but I get concerned when asked to even
"review" intellectual property that's related to the
area I am working in.

If Synopsys charges for access to their standard, then
one should be careful about separating such access from
work on the DC-WG standard, lest it become "encumbered".
There seems to be consensus that its desirable for the
standard to be freely available- a topic of some discussion
with regard to the Cadence donation.

Perhaps it would be best to let Synopsys compare the
direction of DC-WG versus Synopsys Design Constraints (SDC)
until the legal implications are understood.

Sorry, Ibna.

Respectfully...... Bob
