Dual Logo Procedures
Alex Zamfirescu IEC USNC TA TC93
Convener IEC TC93 WG2
November 2004

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
![Page 3: Dual Logo Procedures Alex Zamfirescu IEC USNC TA TC93 Convener IEC TC93 WG2 November 2004.](https://reader036.fdocuments.in/reader036/viewer/2022082620/5a4d1b027f8b9ab059987667/html5/thumbnails/3.jpg)
Proposed Plan
• Walk through the information flow – identify and agree on areas for improvement/refinement
• Discuss the general major topics1. Actual flow requires that versions of the draft are produced and
reviewed - 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 constrained4. 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 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”

Dual logo maintenance process see pages 2/3
An IEC-TC/SC needs to revise an IEC-IEEE standard
IEEE needs to revise an IEC-IEEE standard
MCR PAR
IEC and IEEE agree on a common need
YES
Dual logo maintenance team (DLMT) set up with members from IEC and
IEEE and a convenor jointly accepted ( see note 3 )
IEC disagreessee note 1
IEEE disagrees see note 2

Maintenance
Procedure
The DLMT prepares a draft for comments (CD)
IEC National Comments( 3 months )
IEEE experts internal ballot( electronic )
The DLMT prepares a common compilation of comments with possible proposals for change
IEC-TC/SC takes decision by correspondance or at a TC/SC meeting
CDV OK? See note 4
IEEE takes decision for the next step ( possibly a second internal ballot )
INFO
Ballot OKSee note 4
The DLMT prepares a second draft based on commonly agreed changes
IEC votes on CDV(5 months)
IEEE sponsor ballot( 30-45 days )
INFO
NO NO
YES

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.
