6. Inter-group Collaboration

  • None.

7. Discussion Topics

7 a) P2654 C4 Model perspectives

  • {Slide 14}
  • Brad described and demonstrated the methods for editing and extending C4 Model diagrams, and detailed where the PUML (Plant UML) files could be found on his GitHub site.
  • "Person" is really a role and essentially equivalent to UML's "Actor".
  • Discussions largely centred around "ATPG" and manual TPG and what terminology might be most appropriate for each category. This was not fully resolved.
  • The scope of "Automated/Automatic" in ATPG may be subject to interpretation.  Usual inference is that the test generation is automated, but could be read as implying that the tests are applied automatically.
  • Noted that "Cluster Tests" could not reasonably be taken to be only automatically generated or only manually generated: While some tests could be automatically generated based on CAD/device model data, other cluster tests may require design knowledge or intent that requires human input.
  • We're looking at board-level currently, system-level in on another diagram.
  • «System» doesn't equate to our view of what a system is and the term, like some others, is a carry-over from using Plant UML as the diagramming basis.
  • Reminder that the value of the C4 Models is the ability to tunnel down through the diagrams to increasingly finer detail.

8. Any Other Business

  • {Slide 15}
  • None.

9. Glossary: 

  • None
  • Carried over:
    • 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.
