I am trying to find information on how the package hierarchy work with the new
BIRD189 syntax.
This is the only thing I could find so far:
[cid:image003.png@01D4960C.B1CCF400]
But this does not say anything about how this "overriding" should be done.
Does this mean that
if I find [Interconnect Model Set] in an .ibs file, that none of the legacy
package models should be
in effect, even if this [Interconnect Model Set] doesn't provide a model for a
bunch of pins, or
does it mean that only those pins which are described by the [Interconnect
Model Set] should
be overridden in the legacy models?
I know we talked a lot about this because there is an added complication here
due to coupled
package models. But if this is the only thing we say, I think it is too vague.
We should try to be
a little more specific, similar to what we did in the [Pin Numbers] section.
This might need a
BIRD, so I am willing to let it slide until v7.1, but we should at least list
it as a known issue...
Thanks,
Arpad
