Xrosstalk talks AMI

Comments(2)Filed under: PCB Signal and power integrity, PCB design, SerDes

There's a great issue of Xrosstalk magazine out there that talks about algorthmic modeling for high speed SerDes channels.  Cadence as well as other EDA companies give their take on the subject. 

Here's a link to the articles:


What are your thoughts?

Thanks for the link to the magazine! Modeling and simulating high speed SerDes channels is definitely a real challenge a lot of engineers are facing now. I think a lot of engineers got comfortable with their 3 Gbps designs and had their design rules down but now at 5 Gbps and above you almost have to start over again. IBIS-AMI is a very interesting idea that allows you to model the complicated pieces of your SerDes design using an open language like C or even Matlab. It's still in the early stages so it will be interesting to watch how it progresses.

IBIS-AMI should become an official standard as part of IBIS 5.0 when the vote takes place by the IBIS committee on August 29.  As Tim says, this is in the early stages, but it might be a good idea to check with your SerDes vendors now to see what their plans are regarding support for this modeling approach.  It is the only way that you will be able to simulate a 6+ Gbps serial link with models from different SerDes vendors on each end of the link.  Let us all know what your preferred vendors are saying regarding IBIS-AMI support.
