Thank you.
So, to SiSoft's key areas of concern:
- Will BIRD 147, as proposed, will allow a TX/RX pair to perform training
during Init and then *continue* to perform training during Getwave?
Our understanding is YES, based on Ambrish's responses in the 9/23
meeting. This needs clarification in the written BIRD, but we understand
the intent.
- Will BIRD 147 permit standardization of the .bci file described by
Walter in the 9/30 meeting?
Our understanding is YES, based on this recent set of emails.
Walter should provide that presentation & .bci file example to be posted
in the IBIS-ATM Work Archive.
Unfortunately, I will miss next Tuesday's meeting as I will be on the road
- I plan to be there for the 10/21 meeting.
Todd.

Hi,
Yes, Ambrish, you have my intent correct.

Hi Arpad,
I believe that is what Ken meant (correct me if I am wrong Ken). After
reviewed by the IBIS subcommittee - it will be IBIS approved and be called
ibis_xyz.bci - where xyz is the requested name.
Thanks,
Ambrish.

Ken,
Thanks for your answer. I think there was another aspect to Todd's
question in addition to what you answered. Is it OK to call that
"private-public" protocol an IBIS approved BCI file? (Todd, Walter,
correct me if I used the wrong words, but I thought this was a big part of
your question)...
Thanks,
Arpad

Hi Todd,
I was planning on addressing your "hinge question" from last week
regarding backchannel in the IBIS-ATM call today, but it was cancelled. So
responding here in email.
OK, so the intent of posting BCI files to the IBIS website for industry
standard protocols (ex. PCI Express, 10Gbase-KR, etc.), is to make them
available to all AMI model developers, enabling them to code their AMI
models to include backchannel functionality for these standards, and
thereby enabling interoperability between AMI models from different AMI
model suppliers for those standards.
If an AMI model developer has control over both Tx and Rx AMI model
development, they can also make up their own BCI file, as long as it
adheres to IBIS-legal syntax, and define their own Protocol_Specific
parameters that the Tx and Rx understand. We have been calling this a
"private protocol". Any IBIS-compliant EDA tool should be able to use
those AMI models along with the BCI file, and everything should just work.
This is all perfectly legal, and you don't need to get the BCI file posted
to the IBIS website or anything. It could just be distributed with the AMI
model kit from the AMI model supplier.
OK, so with that backdrop, your hinge question from last week:
###############################
If SISoft worked together with some SerDes IP suppliers, and put together
Tx and Rx AMI models along with a BCI file for a private protocol, would
SISoft have the option to provide the BCI file to the IBIS sub-committee,
and have it posted to the IBIS website?
###############################
I don't see any reason why not. You wouldn't have to do that, as you could
just give the BCI file out as part of the AMI model kit. But if you wanted
to make it public, and maybe attract others to adopt it, I don't see any
issues with that. It would have to be of legal IBIS syntax and pass IBIS
review just like an IEEE standard BCI file, but then I don't see any
problem with posting it on the IBIS website.
Thanks,
Ken

I need to cancel today's ATM teleconference. Sorry for the inconvenience.
If there are any urgent topics to be discussed I would encourage to use
our email reflector...
Thanks,
Arpad
