Action
Items:
Dave - got in touch
with Greg Maston regarding the specs/selector/category portion of the STIL 1999
specification, regarding the longevity (persistence) of the Meas data. There is
presently (in the STIL 1999 spec) to put information into the Meas and to
reference it from elsewhere. Ernie: - but what if you refer to a measurement
that hasn't been made yet? Jim: - does the syntax for an equation constrain it
to be numerical only? or can it have other "types" such as text strings or
something that means "not a number"? (the consensus is "not
yet").
Some general
discussion regarding the mechanics of .Meas in the STIL 1999
spec.
From our perspective
(STIL.4), we may have the following issues to resolve: a) what if there is a
reference to a .Meas - before a value is assigned into the .Meas?, b) what if
the selector identifies an undefined (empty) expression?, c) how to get a
measured value into the .Meas? d) what if a .Meas is used by the next serial
number device for which it is not applicable (this is one of a few different
"persistence" issues).
Possible
resolutions: 1) a selector block which does not specify all of the specs in use
then a) user can refer to the desired expression explicitly, (such
as var.Min) b) any undefined expressions take the value from an
adjacent expression (i.e. if Min is specified, but Typ isn't, then Typ
would gets its value from Min) (we think this may a problem if Min & Max are
specified, but not Typ), c) require this to be a run-time error (when the
undefined expression is referenced).
Discussed various
persistency issues: a) until end of test, b) until end of device, c) until end
of lot, d) until the program is unloaded, e) even beyond the execution of this
program.
(we didn't get to
item #2 on the agenda).
