Fangyi, Walter,
There are a couple of spelling mistakes in this paragraph
(marked with red bold):
As mentioned above, a Retimer Rx must has AMI_GetWave (GetWave_Exist = True)
and the AMI_GetWave function must return clock_ticks. The simulation platform
shall generate a digital input to the Retimer Tx by sampling the Rx AMI_GetWave
output waveform ½ UI after each clock tick, The digital stimulus shall have
values of -½ and +½ UNITS?.
In step 8b, shouldn't we mention that the resampling should
also include the Rx_Receiver_Sensitivity parameter's effect?
This paragraphs also needs a few editorial changes:
Step 7a. Redriver: The simulation platform convolves the impulse responses
returned by Rx1's AMI_Init in step 3 and by Rx2's AMI_Init in step 6 to
obtained the full channel impulse response and uses it to perform statistical
simulation.
Otherwise I think this is a good BIRD...
Thanks,
Arpad

Walter:
There are probably several other editorial corrections (that a committee can
make),
but a few to catch now are:
Under Transmitter Circuit:
.... within the limitations of SPICE --> ...within the limitations of the EDA
tool
under Receiver Circuit:
in this BIRD --> here
This BIRD defines what that unit excitation is when the Tsonefile parameter is
present -->
A unit excitation is defined when the Tstonefile parameter is present
And four times:
differential buff --> differential buffer
Also in Rx_R:
a reasonable facsimile thereof. --> a reasonable approximation.

All,
Please review version 158.3 (Tstonefile AMI models) before I send the final
version to Michael tomorrow afternoon.
The major change is that there are now two Tx voltage levels (Tx_Vol and
Tx_Voh) that determine the differential step response stimulus that is assumed
for generating the Impulse Response of the channel. This make BIRD158
Tstonefile models directly convertible to BIRD 160 external models, and gives
the model maker the ability to determine the common mode voltage when
generating the Impulse Response of a channel.
