    • No corrections noted.
    • Bard moved to approve, seconded by Jon, no objections or abstentions → minutes approved.

5. Review Open Action Items

6. Inter-group Collaboration

  • {Slide 13}
  • P1500 re-circulation ballot has closed, 35 comments to resolve.

7. Discussion Topics

7 a) Continue Review of Standard Draft

  • {Slide 14}
  • NOTE: New slides have been inserted into the meeting pack as slides 112 - 114 and consequently some references from last week's minutes do not transfer directly into this week's pack.
  • Re-capping and expanding on the material presented last week from Brad's work for P1687.
  • Key Assumption (slide 111) is showing a right-to-left flow for consistency with P1687 conventions.
  • The Target Grammar is stating the objective from the perspective of the application.
  • The Transformed Grammar is the result of transforming the stated objective into instance specific (fully qualified) instructions.
  • Slides 112 - 114 work through a specific example: The top left blue box from "1687 to 1687.1 Transformation Process" maps on to the grey box on the right of the two "1687.1 to 2654" diagrams - different stages of the process, the latter supporting the Transformation Node Model on slide 115.
  • Discussion on how this was different to the approach Peter had suggested that used nested wrappers.
  • Proposition that if all or part of the downstream hierarchy was known (it often is) then than known section could be described like a single node (effectively a black box) which might provide an efficiency and allow easier swap-in of Form-Fit-Function substitutes. 
  • This would work where the injection node was at or above the top of that block.
  • Document was not updated and latest version remains IEEESTD-P2654_Draft_D01_BGVT_20211115.docm.

8. Any Other Business

  • {Slide 15}
  • None.

9. Glossary: 

  • None.
  • Carried over:
    • Network will need to be defined
    • PTPG - Programmable Test Pattern Generator/Generation
    • Better define structural test boundary vs functional test
    • Transfer module/library
    • Injection transfer module/library
    • RVF Message (to be refined)
    • RVF Command (to be refined)
    • "Tooling" - need to be clear on what is meant.
    • "True System".
    • Comment that "End-User" is subject to perspective and so needs to be qualified.
    • ModelPoint.
    • System Element.
    • System Resource.
    • 'System' needs the concept of a controller capability added.
    • "Filtering" may need to be defined.
    • "Translation" may need to be defined.
    • "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.
    • 'Port' needs to be developed.

10. Takeaways:
