2. Agenda

  • Eric moved to accept the agenda, seconded by Brad, no objections.

3. IEEE Patent Slides

  • {Slides 5-10}
  • Patent and Copyright slides reviewed.
    • Noted that P1687.1 had asked about use of IEEE standards within working groups. As IEEE owns the copyright they are available to WGs.

4. Review and Approve Previous Minutes

  • {Slide 11}
  • Meeting #50, January 20 (draft circulated January 20)
    • No corrections noted.
    • Brad moved to approve, Eric seconded, no objections or abstentions → minutes approved.

5. Review Open Action Items

6. Inter-group Collaboration

  • {Slide 13}
  • Proposal for Special Session at ETS 2020 on the value of P1687.1 and P2654 and the synergies between them. Unlikely that we will have anyone attending to directly support this (Jan may be able to attend ETS but will not know for some time).  Current understanding is that P2654 will give a statement backing the presentations.

7. Discussion Topics

7 a) Sketch out an outline of the draft

  • {Slide 14}
  • Bullet points recorded during the earlier meetings are now moved to a separate reference file: http://files.sjtag.org/P2654WG/P2654_Reference_Pack.pptx.
  • Draft outline is in slides 17-22 of this week's pack (linked in the heading of these minutes).
  • Proposal from last week included suggesting existing diagrams that can be used for the standard. Difficult research old slide packs and presentations during the call so take those suggestions off-line.
  • Content topics within sections 5 and 6 expanded textually {slides 18-19}.
  • Additions located to try to follow a logical "flow" of introduction of new themes, but shouldn't be considered definitive at this stage.
  • Some notes indicate where illustrations my be helpful.
  • Resume next week from section 7.
  • Forum thread for comments on the outline: http://forums.sjtag.org/viewtopic.php?f=3&p=1444#p1444.

8. Any Other Business

  • {Slide 15}
  • IPC APEX: Louis would prefer to work with the five slides already sent to IPC, but would like some notes added so he has a "script" to work from if asked questions.  Brad hasn't seen the slides (they are simply the graphic blocks from the ITC Poster exported to individual slides), so Louis will pass them on.

9. Today's Key Takeaways

  • None.

10. Glossary Terms from This Meeting

  • None.
  • Carried over:
    • "Interface" is missing.
      • No obvious IEEE accepted definition.
      • 1687 has definitions for specialised forms: Device Interface and Instrument Interface.
      • We may need specialised forms for Software Interface and Hardware Interface.
      • "Interface" is overloaded and requires disambiguation.
    • 1687.1: Transformation.
    • IEEE 1856: Sense - "Sensor" done, Acquire, Analyze not really defined.
    • Device - do we mean a packaged device? May be many devices in a package. "Device" is often used as a modifier, e.g. "device package", "device identification".
    • Use Case Context, Application Context
    • Legacy Infrastructure, SJTAG Infrastructure (placeholders for now, really for working group to define).
    • "Generators": May need to be qualified as "Test Generators" (used by the integrator/tester) and "Model Generators" (used by IP providers, interface designers, etc.).
    • AccessLink and DataLink descriptions will need to be revised.
    • See P1687.1's definitions on Slide 31 of the pack presented by Jeff Rearick on Jan 14, 2019.
    • "State", "Vector", "Sequence" and "Pattern" as proposed at April 8, 2019 meeting.
    • "Event", "Access Interface" as proposed at April 15, 2019 meeting.

11. Schedule next meeting

  • February 3, 2020.
    • Absences: None advised.

12. Topic for next meeting

  • Continue on outline of the draft from section 7.

13. Reminders

  • None.

14. List New Action Items
