Review of ARs:

- Mike update macro library documentation
  Will do it this week

- The modification of the API BIRD to accommodate the Pole-Zero approach will 
be tabled for now.  We will attempt to go ahead with the
  time-domain proposal for now, then later on address modifications for the 
frequency-domain approaches.

- Public domain HSpice syntax
  Todd has sent email to Synopsys, no response yet

- Syntax proposal for parameter passing BIRDj
  No update from Arpad yet

New Discussion:

Todd gave a presentation describing serdes concepts and terminology:  "Serial 
Link Analysis Terminology"
for us to standardize on.

Arpad:  Is "Equalization" an appropriate term for the waveform processing done 
by the transmitter?
Kumar:  Good point, "filtering" may be more appropriate in this context
Todd:  No problem to change, just wanted to put a stake in the ground with this 
prez.

Arpad:  May want to include some feedback loop in the picture of the RX section
All:  Where should we delineate the RX?  Where should the RX model boundaries 
be?
Todd:  Should there be any possibilities made for the RX to return data to the 
EDA tool?

Todd:  Is an API really necessary for the TX?
Kumar:  Didn't want to proscribe any implementation.  In the case of certain 
optimization schemes, will need TX to be more
        algorithmic, so API probably necessary.

Todd:  IBIS presupposes some structure for a buffer.  Do we need to do the same 
here?  At least give it some structure, instead of
       trying for ultimate flexibility?

- Init() call is processing impulse response.
- GetWave() call is processing data stream.

Walter: driver has no idea what the receiver is doing unless there is a
back-channel.
Mirmak: model makers will be using statistical analysis, not building a
real-time functional model.
Walter:  Do we want the EDA tool to be handling the optimization, or the model?

AR:  Kumar will incorporate some of the terminology, as presented in the SiSoft 
presentation, into his API proposal, especially into
     the examples.

Todd:  Is IBM or TI or (??) willing to expose their parameters, or their 
filter, to the EDA tool?  Would this be exposing too much of
       their secret sauce?

Bob R.:  It's not exactly clear to me where h(t) is in the presenation.
Todd:  h(t) is passive channel only.

AR:  Todd will send presentation out to group, and Mike L. will post on website.

Next meeting: Tuesday 19 Dec 2006 12:00pm PT
