IBIS AMI Backchannel Reflector Overview

The IBIS AMI Backchannel Reflector is maintained by IBIS

Goal is to produce an IBIS BIRD that will

Enable Channel Standards Groups to define communication protocols between
the Tx and Rx DLLs.

Enable IC Vendors and AMI Model Developers to write IBIS AMI models that
are

Portable Model will work with multiple EDA Tools

Interoperable Vendor A Tx will work with Vendor B Rx

Enable EDA Vendors to develop tools that will support AMI Backchannel
models

Two presentations and lively discussion was had at the IBIS Summit at
DesignCon 2011. As a result of these presentations and discussions I will
shortly start several e-mail threads in the Backchannel Reflector. One
important issue brought up was the interface layer(s) that need to be
supported (i.e. does the Rx model communicate to the Tx model in commands
like "Increase Pre-Cursor tap by 3", and/or the actual binary stream that
the Rx sends to the Tx.

The complete set of presentations at this year's IBIS Summit can be found

The two papers presented on SerDes Backchannel were:

Initial discussion topics for the reflector include:

1. Shall we continue to call this "Backchannel"

2. Review of AMI modeling, including statistical and time domain
methodologies.

3. Confirm the mechanism that data is passed back and for the
between the Tx DLL, Rx DLL, and EDA Tool.

4. Determine the generic format of the data passed back and for the
between the Tx DLL, Rx DLL, and EDA Tool.

5. Determine Reserved Parameters that will be used to communicate
information between the EDA Tool and the Rx DLL, and between the EDA Tool
and the Tx DLL.

6. Determine the interface layers that need to be supported.

7. Determine the methodology that Channel Standards Groups (e.g.
IEEE Ethernet, PSIe-Gen3) define communication protocols between the Tx
and Rx DLLs.

8. Consider forming Reflector subgroups that might wish to resolve
issues like the above without overloading the general membership of the
mailing list. Specifically do we need a IEEE Ethernet subgroup and a
PCIe-Gen3 subgroup.
