1. IEC TC93 Liaison Report to DASC Alex Zamfirescu IEC USNC TA TC93 Convener IEC TC93 WG2 September 2004

2. News from IEC TC93 Affecting DASC
TC93 meetings will be hosted at IEEE Headquarters during the week of October 3 to 8
IEEE Std 1603 (ALF) was submitted as DL
TC93 plans to discuss
Interoperability of international standards
Simplification in future DA standardization
Maintenance procedures of DL Stds.
Closer TC93-DASC cooperation envisioned

3. More on IEEE-IEC Dual Logo Agreement

4. 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”

5. Current IEEE DASC Dual Logo Submissions
Computer Society/Design Automation Committee:
IEEE Std – IEEE Standard for Standard Delay Format (SDF) for the Electronic Design Process.. (IEC )
IEEE Std – IEEE Standard VHDL Language Reference Manual ………………………………….. (IEC )
IEEE Std – IEEE Standard Verilog® Hardware Description Language …………………… (IEC )
IEEE Std – IEEE Standard for VITAL ASIC Modeling Specification……………………………….. (IEC )
IEEE Std – IEEE Standard for Advanced Library Format (ALF) Describing Integrated Circuit (IC) Technology, Cells, and Blocks

7. 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 OK
See note 4
The DLMT prepares a second draft based on commonly agreed changes
IEC votes on CDV
(5 months)
IEEE sponsor ballot
( days ) NO
YES
See note 5

IEEE final ballot. Once approved IEC submits the FDIS for final vote (2 months)
See note 7
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 or at a meeting
IEEE takes final decisions on the comments received
INFO
The DLMT prepares the FDIS based on commonly agreed modifications.

9. 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.

10. Much Needed Joint IEEE/DASC-IEC/TC93 Efforts
Establish procedures to address DL Std issues
Develop roadmap for next generation standards
Common numerics! (involve DATC)
Formal specifications, information modularity
Develop strategy to cope with standardization complexity
Develop strategy to involve industries as well as experts from all the globe
