Has anyone ever tried to simulate the effect of serpentine coupled lines in
SPICE?
The scenario is 6 mil lines running through many slots of 2mm shielded
connectors. With two tracks per channel, these data traces are serpentine,
and couple closely every time they go around ground contacts, with 6 mils
spacing and 8 mils spacing to ground.
I was thinking of creating 3 distinct LRC tline models and cascading them,
any thoughts on the accuracy of this?
These data traces are routed to vias at most slots, so there will be
capacitive coupling from the vias also. Has anyone found this situation to
create significant crosstalk (>3%)?

Thank you very much,
