Hi all,
I need to calculate equivalent lumped capacitance seen by an IO driver
which is connected to PCB trace (approx 3 Inches) and then cable. The average
rise/fall time is 600ps. I have information about the PCB trace
capacitance/inches. Will my assumption be correct if I take PCB-trace length
(for lumped-capacitance calculation) which provides 300ps delay.
What would be the best way to simulate IO driver as far as
rise/fall time accuracy is concerned assuming lumped model for Tx line.
Thanks
sushil
