Just in case anyone is following this, some more updates. Silkscreen, via moving, more efficient traces, etc...
I plan on laser engraving the layout on monday to check pad layouts, then ordered on Tuesday. from Advanced Circuits. I have all the parts in stock, so there will be no waiting there.

Before you do that, here is the updated files. This has a Breakout on the same file.
I moved one of the connectors to the middle of the board, want to see if you can do that with the other?
I added a third connector for power, but I don't intend to use it. Its just there if its needed.
I would also appreciate it if you could check to make sure the male/female connector pins map correctly to the XTAG connector.
Plan on ordering once you take a look!

Moving that connector will take a while... and really I do not see the benefit... I always thought connectors near the edges of boards were preferred to the ones in the middle... Give me please a couple of days.

That is fine, I guess it provides a polarization.
Don't bother with that, just checking!
Thanks!

Update! I just pattern'd the boards, so I can get 8 breakouts and 8 boards from one run. I have to cut it my self, and it wont be as good of a cut, but hey, it saves money!
BTW, when you are checking, check on the PCB vs component datasheets. I want to eliminate the possibility of a mistake in a library ruining the lot.
I didn't bother uploading the schematic as they are not consistent, and it is the same.

I updated the panel. I removed 4 of those breakouts, and added 4 of another type. This breakout is more practical to use in designs.

Updated just the main board. I didn't realize that I just needed to connect two mode pins to TRST_N to have it automatic, so I connected those. Since that pin is right next to the mode pins, I was able to cut a lot of stuff out, and pushed the entire left side towards the processor. This decreased board length by .0625", so I added that length on the other side and was able to bring out 2 more 1 bit ports.

Here is what I am going to send to the fab house.

The panelized PCB arrived today, hopefully it is ready to test soon.
