Hi all,
I just finished updating the channel equalization optimizer in *PyBERT*.
I chose to use the *Pulse Response Zero Forcing* approximation to DFE behavior
for this.
I got curious about the accuracy of this approximation, and dug into it fairly
deeply.
I posted my work, in hopes that it is of interest to, at least, one other
person on this list:

I can, usually, be found at the Hyatt lobby bar for an hour or so, after the
DesignCon show floor closes, if anyone would like to discuss this in person.
Hope to see you all, at DesignCon,
