Regarding [Test Load], we might want to enhance that to allow IBIS-ISS test
loads. That would remove one barrier to adding it to the IBIS files, in the
case where the model maker has data, but it's for a fixture that does not map
to the fixed topology of [Test Load].
Regarding Lance’s idea on external [Test Data], that could be CSV files, or we
could define yet another IBIS extension to contain all test data (and maybe the
test load too, to keep them together). I think I would prefer CSV, to make
creating the files easier. But then, how long before someone writes the BIRD to
put all I-V and V-T tables in external files?

Re:
Should we also consider adding the parameter settings (if differ than the
defaults in .ami file), Eye Opening/BER for the defined fixture/channel?
“Eye Opening/BER” are not outputs of the channel, they are outputs of the EDA
tool processing the Impulse Response output of AMI_Init or the waveform
output of AMI_GetWave. IBISCHK has no way of verifying this. There is no
specification on how “Eye Opening/BER” is calculated. If the Model Maker sets
the “Eye Opening/BER” generated when running the model with this test data on
EDA Tool A, there is no expectation that the user will get the same answer on
EDA Tool B. Who is to decide which EDA Tool is “Right”.

Hi Michael,
This is indeed an interesting idea, and it will be a great improvement
related to IBIS quality (for AMI models), I think.
In my experience, AMI users often face the different results given by
different simulators. This new feature would at least give a model vendor's
expectation for the simulations using given test fixture/channel.
Should we also consider adding the parameter settings (if differ than the
defaults in .ami file), Eye Opening/BER for the defined fixture/channel?
Also, there are some "complains" about the IBIS file size (too large due to
[Test data]). We could use this opportunity to redefine waveform attachment
for the [Test data].
My 2 cents,
Best regards,
Lance Wang

Please find enclosed my slides from today's IBIS-ATM meeting, regarding
expanding the existing [Test Data] and [Test Load] keywords to support AMI
model testing. I greatly appreciate the thoughtful feedback and suggestions,
and will incorporate them into any eventual BIRD.
