Friendly Greeting
Worked for 12 mins 4 sec
The preflight improved after correcting an inherited 2 mm trace-width rule, but the board still has footprint-level pin conflicts and many inaccessible pads. I’ll proceed with the router so it can complete every connection that is physically feasible, then report the exact residuals.
Worked for 35 mins 40 sec
Auto-routing has been applied to all feasible connections. I’m running the final board checks now and documenting the remaining footprint-level blockers.

His Holiness, Señior Solveig, I applied placement optimization, removed obsolete routing, corrected the inherited 2 mm trace-width rule, and ran a fresh auto-route. The router added 354 traces/vias, but 117 airwires remain because of inaccessible or overlapping footprint pads.
Open items
- Duplicate/overlapping
U5footprints. - Invalid pad overlaps within
J4andIC2. - Numerous blocked pads around
U3and several 0201 passives. - One locked legacy trace could not be removed.
- The PCB is not yet manufacturing-ready.
Suggested next steps
- Repair or replace the malformed footprints and duplicate
U5. - Unlock and remove the remaining legacy trace.
- Re-run placement and routing after those corrections.
- Perform a final manufacturing DRC review.
