Re: Agenda and slides for Nov 2006 meeting

Dear Victor:

Thank you for the quick reply. Note that at this time there are already
two divergent valid Verilog standards, the IEEE Verilog 2005 and the
international DL IECC/IEC Verilog standard, and that this is not a
consequence of anything done in IEC.

The maintenance process for Dual Logo International Standards
is not only an IEC process but an agreed upon IEEE/IEC one.

In the DASC we can debate what worked and didn't work for us and
try to make this work as smoothly as possible. However, at this time
the next step is a reply from DASC about DASC desirability of participating
in the international standard maintenance of Verilog. Could you provide such
answer, or we need a motion and a vote on it?

Note that I am just acting as Liaison, and I can not guarantee any result,
what will be decided about the next version of the IS will be in the hands of
the maintenance committee, which could be a joint IEEE/IEC one, if DASC accepts
to participate, or only IEC if it refuses. At this time there is no
other way to
influence the outcome without participation.

As a personal remark I would add that there are several views about
how Verilog should evolve.

A. One, looks at merging the Verilog LRM content into SystemVerilog and
considering SystemVerilog to be the next and unique version of Verilog.

B. A second view considers that Verilog has many users and will continue
to have for many years to come, and therefore there should be two standards
available Verilog and SystemVerilog. This is also given the fact that
it is not clear at
this time if SystemVerilog after LRM merger would be a proper super set of
current Verilog which is in use today. The trend for drastic
deprecation has been
already set in motion with the IEEE 2005 version where PLI completely vanished.

A third less popular view is
C. Verilog should evolve to support new ESL challenges, and cover
design exploration phases where MathWorks or Mathematica are used
today, without possibility of automatic optimizations (manual loops between
HDL tools and high level tools are needed today). This is because
SystemVerilog was designed to solve the top bottleneck from 6-7 years ago
which was verification. The new challenges, SoC support, ESL design,
and Low Power design were less visible at that time. The advocates of C-view
concur that an ESL language should be kept simple to provide for easy
human interaction, and confidence that an algorithm does cover the intent.

Other people may have other views, all we can agree is to stick with the
P&P, not point fingers, and keep a decent and constructive open dialog.

Please remember that the question to be answered is about the DASC
participation
in the Verilog IS maintenance process, and please rest assured that I very much
appreciate the time, your effort, and your interest in the correct
evolution of standards.

Sincerely,

Alex Zamfirescu
