6. Discussion Topics

6 a) Preview of 1687.1 slides for AutoTestCon

  • {Slide 12}
  • Brad took the group through a preview of the P1687.1 presentation that Al Crouch would be delivering at AutoTestCon tomorrow (August 27th).
  • Presentation title: "P1687.1: Accessing Embedded 1687 Instruments using Alternate Device Interfaces other than JTAG".
  • In what form are the callbacks expected to be supplied? Translatable code or a behavioural description? This has not been decided.
  • Are Functional Registers exclusive to 1687.1 or could other functionality in the device also be accessing them? These are a way of making existing instruments accessible at the DPIC. The description comes from PDL and can't really be used by other device functions.

6 b) Recap on past SJTAG survey data

7. Any Other Business

  • {Slide 13}
  • None.

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
    • LRU and SRA.
