Discussion:
IEEE meeting clearances
Nothing under discussion or presentation for this meeting was identified as being proprietary or restricted.
Dot1 status
- no vote causing heartburn. (ai-4, done)
Dot3 status
extension through '06 (ai-5, done)
AI-1: update spec for "extended memory counting"
Greg is still working, AI-1 still open
AI-2: create TRC for the Teseda tester using the D09 draft
Bruce had several email discussions. One proposal was copied around to the dot-3
group, to support a "|" option to support defining multiple blocks with
selection or identification of only 1 of those blocks in order to pass the
constraint checks.
Some discussion followed about the issues with these choices - for instance,
failing a block when there were other blocks available may not be informative
(because a "pass" is established when at least one block passes, even though
others may fail). So errors about failing blocks may not be pertinent until it's
known that ALL blocks fail - and once all blocks fail, you probably want to
generate errors for each block so the user can review what's the closest
possible match (which may not be the block with the fewest failures).
AI-3: address issues listed in "Dot3" (5/19 minutest)
on-going
AI-6: solicit pin-file formats
Jason volunteered to contact Inovus for their pin-map format.
AI-7: re-vamp the sub-set proposal and take it to the UG
done.
Discussion about
"intent" of a TRC file
Jason raised some questions about maintaining test intent. For instance, when,
in a test program, is the specified timing critical or not? For example,
consider scan behavior and shift timing, vs. path delay launch-capture timing:
the shift timing is flexible with no loss of test functionality, but the path
delay timing may not be (additionally, it may be only one particular event-pair
in this operation that is critical...). Test rules might not be violated because
of shift timing, if the shift timing is modified a bit, but the path delay
timing shouldn't be so freely toyed with.
The discussion wandered around whether this was a specification of the test
program - or even part of the device spec - or was this part of the constraints
problem? Jose proposed that the tester definition file defines maximums, but
that a subsequent operation maps onto tester resources.
Tony speculated on the need for more application-options to identify the purpose
of various TRC blocks, to support a "maximum values" block vs. a block that is
intended to check resource allocations.
No specific actions were indentified with regard to this issue, however, it is
expected that this will be examined further in the context of specific TRC files
that are being created.
