Tesla,
1st, I would consult with the creators of your AMI model and ask for a
correlation report which shows how well the AMI model matches their
reference data. This will give you a feel for how accurate the your AMI
model is, and should give you some kind of error bound of its behavior.
2nd, I would evaluate your simulated system at the BER level as required by
the interface specification. If your model is capable of also running
Statistical Analysis (in addition to the bit-by-bit time domain analysis),
this is a very nice way of obtaining a BER bathtub that goes low enough
(1e-15 or lower). I would suggest that you take advantage and use this
mode of simulation in addition to the Time Domain mode. If you don't have
this mode of simulation then I would certainly simulate more than 10e6
bits. I regularly simulate 2e9 bits or more.
Good luck,

Hi Experts
i am doing a medium loss 10Gbps channel IBIS-AMI simulation. The channel
loss is 15dB at 5GHz. After 10Mega bit by bit AMI simulation, an eye
diagram with 0.65UI width and 0.12V(p2p) height is got at the RX die side.
Is this a good system?How much margin should i allocate for AMI
simulation?
Good day.
Tesla.
