Re: [BP] Simulations for EIT
If we set the Tx time to 25 ps then you will need 890 mV at the die pad
to get 800 mV the package pin. If you use 20 ps you will need only
850mV. So we need to spec Tx transition time. Also the package will add
3ps of Dj whick is a part of the Tx budget.

Charles,
When are we planning the next channel adhoc phone conference?
Should we have one sometime next week? One possible set of goals would
be to report the results for the listed General Idea #1, simulation of
the selected channels with the selected conditions.
I noticed an item missing from these conditions, the transmit
transition time. What does the group thing we should put this at? Also
a second set of simulations on these channels under more worse case
condtions should be done. I'd recommend the change to the conditions to
be: Tx amplitude target=800mVpp, crosstalk=1200mVpp; Tx equalization for
crosstalk set to the preset state; add ideal delays between the
transmitter and channel and between the channel and receiver such that a
worse case result is obtained. Any other worse case conditions not
already covered?
