6. Discussion Topics

6 a) Planning our Standard

  • {Slides 13-19}
  • Bullet points recorded last week are retained in this pack for reference.
  • Organization of standards has differed over time: The layout of 1149.1 is quite different to e.g. 1581 or 1149.10.  Template does not impose any particular structure.
  • "Educational" aspects within the standard should be limited to what gives useful background and context (probably as introductory preamble) and examples of applying elements of the standard (probably within annexes).
  • Some standards give the bare facts and do not offer any guidance on application. It is left to external articles and papers to show how the standard can be used.
  • Bullet points collected last week browsed to see what categories are suggested. Brad added slides to end of pack to collect thought. {slides 21 to 23}.
  • Standards typically classify sections of content as ether "normative", defining what is necessary for compliance with the standard or "informative" (or non-normative) which gives additional information help with interpreting the standard. We can use these as broad headings and sub-classify within those. This is done in the additional slides: Refer to the pack (linked at the top of these minutes).

7. Any Other Business

  • {Slide 20}
  • Posts to SJTAG LinkedIn Group are essentially "private" to the group. Members need to post on their own pages so messages are flowed to their wider contacts. Some Group Managers "recommend" popular postings so that members can share onwards.
  • Joel volunteers to look after social media postings for the group. Apart from LinkedIn, consider Twitter and a Facebook page: May need to consider what "identity" we want for those platforms.

8. Today's Key Takeaways

  • None.

9. 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 meeting.
    • "Event", "Access Interface" as proposed at April 15 meeting
