Follow up...
The IBIS 3.2 spec has no mention of the Model statement needing an
"output logic threshold".
Looks like a Cadence problem?

Subject: model type IO_OpenPullUp and "output logic threshold"
requirement
All,
I got this warning:
"IOCell <LKPT_UP_0P25_1066_strong> is type IO_OpenPullUp and so:
should contain an output logic threshold"
Any ideas as to resolution?
It is purely a warning from the "DML check" performed by the Cadence
IBIS simulator's parser. I've started an inquiry into this one because
I can't find reference to this issue in IBIS specifications regarding
this model type requiring logic threshold data.
I have these lines in the IBIS file:
[Model] weak
Model_type I/O_open_drain
...and the same for strong and typical.
Thanks,
John
