									Dual Logo Procedures
      Alex Zamfirescu
  Convener IEC TC93 WG2
       November 2004

• 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
                        Proposed Plan
•   Walk through the information flow – identify and agree
    on areas for improvement/refinement
•   Discuss the general major topics
      1.   Actual flow requires that versions of the draft are produced and
               -   simpler for std in maintenance
               -   editor on duty
      2.   Harder to understand IEC document circulation rules
               »   DASC should be minimally affected
      3.   With extra rules IEEE groups might feel unreasonably constrained
      4.   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
Submitting Dual Logo Candidates
           to 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

            The DLMT prepares a draft for comments (CD)

          ( 3 months )                          ( electronic )

            The DLMT prepares a common compilation of
            comments with possible proposals for change

 IEC-TC/SC takes decision                 IEEE takes decision for the
 by correspondance or at a                next step ( possibly a
 TC/SC meeting                            second internal ballot )

                The DLMT prepares a common compilation of
                comments on the CDV together with
                proposals to solve them

    decisions on the comments          INFO         on the comments received
     by email or at a meeting

                     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
•   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.
