Hi Eric, given how fast the standard is evolving and how varied the
vendor's interpretations are, it seems like there are some significant
differences in the AMI models I've seen. I have to concur with the other
responses that an "out of the box" AMI implementation is a bit unclear.
One convenient way that some EDA vendors are allowing customers to get
meaningful simulation results immediately is through vendor specific
design kits. The end user only needs to input their specific channel
(s-parameters, w-elements, field simulations, etc) and tweak some
parameters to match their specific devices. Ansoft has one of these
design kits available using the latest released version of Designer and
IBM HSS15 models. There is an overview of this kit, as well as HSSCDR
correlation available at
http://www.vhdl.org/pub/ibis/summits/nov09a/herrick.pdf. Although I have
not yet put together official design kits, we also have working AMI
examples from Rambus, Broadcom and Xilinx. Of course you will need to
contact these companies individually to obtain the models.
Thanks,
Chris

Subject: [SI-LIST] IBIS-AMI Vendor Support Help
Hello
I have been looking at channel designers from Mentor, Cadence, SiSoft,
and Sigrity that claim to support AMI models. However, to date I have
only seen Sigrity's channel designer support AMI models "out of the
box", and can generate the BER curves, and statistical eye's.
In the case of Mentor, it looks like they only have special support for
the Xilinx models embedded within the kit (? is this correrct ?). I
assume this means Mentor does not yet have a tool where you can take any
vendors AMI model and just drop into a schematic unless you work with
them to develop a kit similar to Xilinx.
Does anyone know if/how Mentor (Hyperlynx GHz), Cadence (Signal
Explorer), and SiSoft (Quantum Channel Designer) support out of the box
AMI models?

Eric
