Ken,
I would not abject if the IBIS-ATM committee votes to remove
Samples_Per_Bit from BIRD 121. We put his in BIRD 121 because certain IC
Vendors wrote models that would not work properly unless they were given
data with a specific number of Samples Per Bit (32 for the following
comments).
In order for IC Vendors to create compliant models, they will need to
rewrite their algorithms, or convert the data on input to 32 samples per
bit, and convert it back on output.

Hi Walter,
In the Data Management BIRD # 121, we do not like the idea of dictating
"Samples_Per_Bit" requirements on a model-by-model basis. This is a
dangerous approach. The models need to be developed such that they are
robust enough to handle the impulse response/waveform time domain data
they are presented with by the EDA tool. And there are also compatibility
issues that could arise if the Tx DLL wants one kind of sampling and the
Rx DLL wants another one. We think this parameter should be taken out of
the BIRD.
Thanks,
