Binary Wristwatch Design

Worked for 34 sec
Post-placement review shows the board is physically placed, but routing congestion is high around the MCU/SWD header/button area. I’m going to make a focused placement adjustment before routing so the autorouter has enough escape room.
Worked for 4 mins 37 sec
I adjusted the placement to reduce the worst congestion around the MCU and programming header. I’m starting routing now; the board is still compact, so I’ll verify carefully afterward.
Worked for 18 mins
Continued the PCB layout work: I adjusted placement to reduce congestion, routed the board, removed one overlapping trace, and ran a cleanup routing pass.
Current status: the board is mostly routed, but 2 airwire issues remain, both tied to an automatically generated copper fill/stitching connection that I couldn’t safely delete with the available layout controls. There are no remaining overlapping-copper errors in the checked set; next step is a manual/targeted cleanup of that fill or a small routing/ground-pour adjustment before manufacturing export.
