For those able to attend EDAP conference, there are several SI/PI tutorials
planned.
Here is the website with descriptions:

There are several things wrong with your eye diagram,
for one, it doesn't seem that you have enough bits in
it, but the waveforms which make it up contain too many
wiggles which indicate lots of reflections in your
layout.
As I said before, I don't think you should expect to
get your training from emails in this forum. Please
take a class or read some books, or at the minimum
do a Google search on the topic. Here is one link
I found by typing "eye diagram" into Google:
http://www.highfrequencyelectronics.com/Archives/Nov05/HFE1105_Tutorial.
pdf
and there are many more...

I have uploaded eye-diagrams whatever i have captured in the following
link in picasa. Please clarify.

Subject: [SI-LIST] Query on Eye-Diagram of RX ADC
Hi Techies,
I have a question on Eye-diagram. We are having an interface
between ADC
and
Virtex-5 FPGA. this interface is High-Speed differential
interface. Iam
simulating the interface with Hyper Lynx BoardSim. I want to
know What
are
the things i need to look up in the simulation so that i can say
my
layout
is fine?
I have generated an eye-diagram using HyperLynx but what exactly
it will
tell. As far as my knowledge is concerned an eye-diagram can't
tell us
that
our impedance matching and our layout is correct. Correct me if
iam
wrong.
Can you just share me your thoughts on what to observe. Iam new
to SI
tool
and analysis so please help me in this. Iam also attaching my
simulation
results with this mail. Please let me know how to add files as
this
group is
not allowing pictures to be shared.
Thanks & Regards
Srikanth Chundi
