Hi Mr Gert,
Thanks for your recommendation! It's very helpful to me.
And I have one more question below:
To verify the channel which have the frequency is larger than 3Ghz (ex.
PCIE3.0/4.0, XFI). What is the accuracy simulation tool? How about Cadence
Sigrity?
Thanks.

Hi Hung,
it really depends on the area you are woking, the signal speed and the
desired accuracy.
Especially the signal speed/edge rate makes a lot of difference because at
really high digital speeds you need to get firm with Material Properties,
Weave effect, Periodic loading, skin effect and so on. Thats a really wide
field, that is not covered in many books. But in this area Hyperlynx will
not give you the needed accuracy in an effective process. Up to 3Gbps you
can use Hyperlynx for Channel simulations with good accuracy.
Besides reading Books I recommend a "learning by doing". I think the best
thing to start with is to first verify Measurement and simulation starting
with some easy straight trace (including Coax connectors), and then go
ahead with a Channel that also contains a two PCBs and a connector. The
differences you see in the beginning will lead you to the topics and Papers
that have the desired information. Look at the data in single ended,
differential, time- and frequency domain, all must be the same in
simulation and measurement. After this exercise you will have a different
view on simulation, tools, PCB-materials, PCB Manufacturing and so on, and
you will be more effective in reading books and papers.
Good luck,
BR
Gert

Subject: [SI-LIST] How to begin to study Signal Integrity
Hi Experts,
I have started to study SI for 6 months. Begin with Signal and Power
Integrity-Simplified book and some tech-doc, app note from Hyperlynx.
Currently, my job is extracting S-parameter and verify SerDes by IBIS-AMI
simulation.
Can the experts give me the recommendations or documents to study SI
effectively? I use Hyperlynx tool to do SI simulation.
Thank you so much.
