next set...

wiggles.jpg is the layer 6 length-matching area: HX2N/P is the one
that's the longest, it snakes back on itself.  i length-matched all 3
signal pairs to 56.413, and left the CK lines at 57.134 just to give
the tiniest bit of delay (TI recommendations iirc).

no - not even enough space to do 5.1mil / 5.0 clearance... just...  too much.

the other images show the via'd portions, they're all either
symmetrical or perfectly length-matched to 0.001mm.
