[Arm-netbook] HDMI High-Frequency Layout: Recommendations

[Luke Kenneth Casson Leighton]

okaay, wiggle-progress... 1st image is left end, i think CX and TX0 i
can shorten even more, there's definitely plenty of space there, big
gap.

2nd image, right end, this is where i've added intra-pair wiggles at
the 45 degree bends.  i can't get away with a proper 4-turn using 45
degrees, PADS goes "nope that's too short a trace, i'm gonna assume
you want a straight line instead" - there's probably an option
somewhere for that but i've not found it.  alternatively i can add in
a (curvy) accordion....

anyway those wiggles are done by hand, some of them aren't pretty but
in mil those traces are now nearly all to within 0.01 mil.  i cheat a
little and have made some of the corners in places a very very tiny
arc, where you get better fine-grain control over the amount it takes
off.

HTXCN just before the diff-pair vias at the end i'm a little concerned
about, it looks a bit too... sharp-angled to make me feel totally
comfortable...  not a lot of space... i tried a single wiggle and it
went too far away from HTXCP for me to feel happy about it.... put in
two much smaller wiggles instead...

GND i'll remove as the absolute last thing.
