Eric,
Its my understanding that Xilinx was the first and currently the only
vendor providing AMI models, but that there are a number of vendors to
announce availability in the not to distant future. Since the AMI model is
wrapped up as a DLL, enabling silicon vendors to model their device
behavior anyway they see fit, the tool vendors and their customers are
dependent on the silicon vendors to jump on the AMI bandwagon. Once the
silicon vendors endorse IBIS-AMI I'm sure the tool vendors will be very
willing to work cooperatively with them to develop and support their AMI
libraries.

If that's not the current state of the market it would be great if the
tools/silicon vendors can list their vendors with available AMI libraries -
or otherwise timetable

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?

Best Regards,

Eric

Marc,

I believe this is a chicken-egg situation. Silicon providers will adopt the models their customers are asking to support. We currently offer Verilog-A behavioral models on the 40nm Stratix IV, but have only recently seen a strong momentum with IBIS-AMI.

All,

I need to point out that IBM drove the development of the IBIS-AMI
standard and delivered the first IBIS-AMI models. IBM had compliant
models ready before IBIS 5.0 was approved in August 2008. Xilinx is a
definitely driving demand for IBIS-AMI adoption, but IBM delivered
models first.

If you are at DesignCon 2010, I invite you to attend our Thursday
paper on IBIS-AMI model correlation to simulation and measurement
(9AM, session 7-TH1), which is co- authored by SiSoft and IBM.

Todd.

Hi Marc and Eric,

Cadence has recently updated the 16.3 release to include IBIS 5.0 support.. This includes the "out-of-the-box" support you are discussing. There was recently a post on the Cadence community blog pages - please feel free to have a look and comment - http://tinyurl.com/yzzaxph.

Thanks and regards,

brad

Thanks for your encouragement, Todd.

We have it in our plans to update the publicly available toolkit. Until then (and after), we will continue to happily answer any questions from customers.

Brad,

That's good news. Is Cadence going to modify their IBIS-AMI toolkit as well? The .ami files in the Cadence toolkit don't conform to the .ami syntax and have been a source of confusion to some.

Thanks!

Todd.
