2. IEEE Patent Slides

  • {Slides 5-9}

3. Review and Approve Previous Minutes

  • {Slide 10}
  • August 28
    • Draft circulated 8/28/17
    • No corrections
    • Heiko moved to approve, seconded by Carl, no objections or abstentions. Approved.

4. Review Open Action Items

  • {Slide 11}
  • [2.1] Bill: Ask Al Crouch about sharing the 1687.1 poster abstract with the group
    • See 5a. CLOSED.

5. Discussion Topics

a) ITC Poster

  • {Slide 12}
  • Poster for IEEE activities do not need to go through acceptance process. Abstract submissions are closed, but an abstract could still be submitted with the poster for inclusion in the proceedings.
  • Could be included in the poster introduction session on the Tuesday, but time is tight, maybe only two or three minutes per poster at most.
  • Bill will not be at ITC this year.

b) TTSC Objectives for group

  • {slide 13}
  • Purpose:
    • Interest:
      • General agreement that the group size shows that there is sufficient interest in the topic to move towards an IEEE standard.
      • That P1687.1 has approached us already to discuss the hand-off between SJTAG and P1687.1 shows that there is recognition of the SJTAG role from other groups. 
      • There are several people in the group that have prior experience of standards development.
      • The Analog Test Access group has a similar size of membership.
    • PAR development:
      • Diagnosis is paramount at system level. How do you deal with false alarms or No Fault Found cases?
      • May utilise "tools" like 1687.
      • Not trying to re-create 1149.5.

  • {Slide 14}
  • Consider:
    • Market acceptance:
      • Too early to think about this.

    • Relationship to other standards:
      • Contact with 1687.1 already started.
      • Analog Test Access not listed on slide.
      • Should we only be considering IEEE standards here? Phrasing suggests so, but there seems no harm in identifying industry standards that we'd expect to leverage.
    • Viable participation:
      • As above, group size seems to be sustainable and could easily grow when the formal standards activity commences.
    • Scope and objectives:
      • 1149.5 had features that should at least be included for consideration. A difference is that while 1149.5 required specific hardware to be implemented, SJTAG is largely hoping to exploit what is already in the design.
      • Analog summing may be used to identify if something is off-line and which item it is.
      • Should not be relying on the features of one or two specific lower-level standards (e.g. 1687). 
      • Maybe we want something that is an open framework that can be expanded.
      • Want to be "future-proof" if possible to accommodate new technologies, perhaps by "plug-ins" to a core standard.
    • New areas of expertise:
      • Presumably relates to opportunities for delivering tutorial and workshops at conferences.

6. Today's Key Takeaways

  • {Slide 15}
  • There is sufficient engagement to support a future Working Group.
  • Need to focus on Scope and Purpose.
  • Need to identify standards we will interface with.
  • Determine the "architecture" for the standard:
    • A single standard we amend or a base standard we complement with further standards?
    • Scope it so we can get it done.

7. Glossary Terms from This Meeting

  • None.

8. Topic for next meeting

9. Schedule next meeting

  • September 18.

10. Reminders

  • None.

11. Any Other Business

  • Both email reflector addresses on the slide are valid and have the same reach. The cisco.com address has been SJTAG's traditional reflector address but we should move to the ieee.org address sometime before transitioning to a working group.

12. List New Action Items

  • None.

13. Adjourn

  • Terry moved to adjourn, seconded by Louis.
  • Meeting adjourned at 12:03 PM EDT

Respectfully submitted,
Ian McIntosh
