RE: Merging modes

Yes. Use the dynamic clamp submodel without pulse
table which makes it static, and specify non-driver mode.
Then copy your I-V curve (pd or pu) into the submodel
as a clamp curve. This will do what you need, and is
legal in terms of the spec.

Subject: Merging modes

I have an I/O where the output PFET is switching when used
as a driver, however it acts as a fixed termination impedance
when used as a receiver. I created two modes of operation
where one mode models the I/O as an output and the
characteristics of the PFET reside in the [Pullup] table and
another mode that models the I/O as a input where I combined
the characteristics of the PFET termination with the power
clamp in the [Power_Clamp] table. This worked ... however the
customer views this as unacceptable because they have to change
model assignments between driver and receiver modes and is
requesting that I merge these modes into one mode using the
I/O model type. Is this possible?

Thanks,
Jerry
