Has anyone investigated the effects of trace 'tromboning' (i.e.,
folding the trace to add length) on flight-time and signal integrity
in general. I'm interested in some rough rules-of-thumb on flight-time
increases/decreases given a fold with a length of 'x' and a distance
between the traces of 'y'. (The environment is current
state-of-the-art 100Mhz+ multi-layer boards). How much separation is
needed to eliminate any problems (assuming the problem is
Also, is this handled correctly in current simulators (such as Quad).
