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.
