Re: PAR scope and direction

In Purpose: The providers of these conforming descriptions are the producers of devices or assemblies with digital interfaces that are intended to be used in an automated fashion within a larger assembly. Would "integrated circuits or printed circuit board assemblies" instead of "devices or assembli...

Re: PAR scope and direction

Here is an attempt to put these "Need Statement" bullet points into sentences. The following would need quite a bit of word smithing, but perhaps it is a start ... While many standards exists at the device level, with diverse feature sets, there is currently no standard that captures the aggregatio...

Re: PAR scope and direction

- in this latest Scope draft, I wonder if “description“ is superfluous in the first sentence? “ This standard: 1) defines a representation of conforming behaviors of interfaces and transformations, ... ” - Should there be an “and” before 2) in the first sentence of this new Scope draft? - in 2), sho...

Re: PAR scope and direction

I think we are stating and restating our positions over and over again. A good analogy might be to consider SJTAG as a standard for drills. There may be many different considerations and different ideas about how best to accomplish making standard drills, but undoubtedly the underlying need for dri...

Re: PAR scope and direction

Perhaps it would help address Louis' concerns if we include a sentence in the Needs statement that says that SJTAG recognizes the need for some form of standardized measurement of test coverage and quality of test, but this standardization effort (this PAR) does not attempt to address that need?

Re: PAR scope and direction

SJTAG is intended to improve the ability to test, diagnose and provide prognostic health information about systems. What about the "need" (?) to program / reconfigure modules / components in a system? Do we want to mention that in this list? Or do we want to focus on test and let programming/config...

Re: PAR scope and direction

In that case I'd think "Need B" would need to be supported by a standard first, and then additional standards / extensions can be developed for various use cases (such as "Health Reporting"). Then, perhaps, the "original" purpose statement could be taken as is / tweaked as needed to fit "Need B" and...

Re: PAR scope and direction

So, are we now considering to mention specific use cases in the Purpose statement of the PAR for an initial SJTAG standard, referring to "test and diagnostics"? A previous draft "purpose" didn't mention specific use cases: The purpose of this standard is to provide a means to seamlessly integrate co...

Re: Suggestions for ITC Poster, 2017

To expand on the outline for the poster, I'd suggest we include: a definition for "system" (to be commented on / picked apart by the audience Configurations (Target level, device/subsystem/system...) <-- anybody have a suitable drawing(s) ? show the "SJTAG Universe" Venn diagram (mentioning that the...

Re: Study Group title and Call for Participation

Based on feedback so far, and on some input from Adam Cron regarding what is required for the call for participation invite, I have revised the draft for further review/discussion: This is a call for participation in the "System Test Access Management" Study Group (also referred to as 'SJTAG'). Thos...

Re: Study Group title and Call for Participation

We can always ask Adam Cron if he really has a strong objection to SJTAG, and if he doesn't we could just keep it. The concern was that that name may make people think we are only addressing the JTAG infrastructure, while we actually now consider other interfaces, too (such as I2C, SPI, etc.).

Study Group title and Call for Participation

(Keep in mind that whatever we choose as title for the study group doesn’t necessarily need to be used as the eventua...

Re: PAR scope and direction

Based on hints given in the scope and need statements, I'd propose something along the following to be part of the purpose statement: The purpose of this standard is to provide a means to coordinate component access topologies, interface constraints, and other dependencies at the board and system le...
