Hi all.
I'm simulating an extracted view for a R-DAC. On my simulations results I'm seeing differences on DAC settling time between coupling and decoupling cases up to 20ns.
What would be the extraction method that best fit with Silicon Results?
My reasoning says me that coupling will be the most realistic because on decoupling method the capacitances are equally sum and tied from each node to ground.
I think that decoupling extraction is more used to reduce computational effort.
Thanks!
