Facts

• Both VHDL and Verilog are DL standards
• Both standards are in maintenance
• Dual Logo maintenance procedures were approved by
  IEEE and IEC, but require pragmatic validation
• Some procedure details have to be filled in

3
Proposed Plan

• Walk through the information flow identify and
  agree on areas for improvement/refinement
• Discuss the general major topics
• Actual flow requires that versions of the draft
  are produced and reviewed
• simpler for std in maintenance
• editor on duty
• Harder to understand IEC document circulation
  rules
• DASC should be minimally affected
• With extra rules IEEE groups might feel
  unreasonably constrained
• What are the first time process tune-up
  procedures
• Joint work to write procedure details, approval
• Execute maintenance for VHDL and Verilog
• Review and Update DL procedures

4
Submitting Dual Logo Candidatesto the IEC

• Candidate is formally submitted to the IEC
  Central Office
• IEC reviews candidate
• IEC Central Office sends a Question of Principle
  (QP) ballot to the SMB
• Should this document move forward as an IEC/IEEE
  dual logo document?
• If the ballot passes, the document is sent to the
  appropriate IEC TC for fast-tracking

Current IEEE DASC Dual Logo Submissions

• Computer Society/Design Automation Committee
• IEEE Std 1497-2001 IEEE Standard for Standard
  Delay Format (SDF) for the Electronic Design
  Process.. (IEC 61523-3)
• IEEE Std 1076-2002 IEEE Standard VHDL Language
  Reference Manual .. (IEC 61691-5)
• IEEE Std 1364-2001 IEEE Standard Verilog
  Hardware Description Language (IEC
  61691-4)
• IEEE Std 1076.4-2000 IEEE Standard for VITAL
  ASIC Modeling Specification.. (IEC
  61691-6)
• IEEE Std 1603-2003 IEEE Standard for Advanced
  Library Format (ALF) Describing Integrated
  Circuit (IC) Technology, Cells, and Blocks
• IEEE Std 1076.6-2004, Standard for VHDL Register
  Transfer Level (RTL) Synthesis
• IEEE Std 1364.1-2002, IEEE Standard for Verilog

Maintenance Procedure
Revised IEC-IEEE standard
The DLMT prepares a common compilation of
comments on the CDV together with proposals to
solve them
IEC-TC/SC takes final decisions on the comments
by email or at a meeting
IEEE takes final decisions on the comments
received
INFO
The DLMT prepares the FDIS based on commonly
agreed modifications.

Maintenance Procedure Notes

• Note 1 IEC may decide to continue its own
  route. If any material is used from the IEC/IEEE
  standard, a separate license agreement will be
  required.
• Note 2 IEEE may decide to continue its own
  route leading to publish a revised single IEEE
  logo standard replacing the previous one. If so
  IEC will withdraw the existing IEC-IEEE standard.
  Then IEEE may submit to IEC this new standard as
  a candidate for a possible new IEC-IEEE standard
  according to the agreement.
• Note 3 The organisation which initiates the
  process, proposes a convenor first. If the
  proposal is not accepted by the other
  organisation, another convenor has to be chosen
  amongst the members of the DLMT by mutual
  agreement.
• Note 4 At this stage, IEC or IEEE are requested
  to task the DLMT to provide a new draft for
  comments
• Note 5 The 2 ballot processes must be carried
  out in such a way that the deadlines are the same
• Note 6 At this stage, IEC or IEEE may decide
  either to continue their respective route or to
  task the DLMT to provide a new draft for vote by
  both organizations. If IEC decides to continue
  its own route, then note 1 applies. If IEEE
  decides to continue its own route then note 2
  applies.
• Note 7 The comments made at this stage must be
  limited to corrections of misspelling or obvious
  errors which may have been generated during the
  preparation of the FDIS.
