I re-routed using the active 6-layer stackup: fixed the auto-positioned TP pad blockers, reduced trace width for U1 fine-pitch routing, cancelled the stale out-of-credit route job, and ran two routing passes. Airwires improved from 53 → 9, but the router left 9 airwires, 3 overlapping-copper errors, and 22 dangling-trace warnings.
Open items:
- RUN/GND connectivity is not clean: verification shows the RUN-side reset pins are still in a separate 12-pin net labeled
GND despite repeated attempts to move them to RUN. I escalated this as a platform/data-repair issue.
- Remaining DRC: 9 airwires, 3 overlapping-copper errors, 22 dangling-trace warnings.
- Auto-route preflight still reports a duplicate-via cleanup warning.
Suggested next steps:
- Repair the RUN net manually or via project history/data repair before manufacturing.
- Re-run ERC on
SW_RESET, U1:RUN, R_RUN:P1, C_RUN:P1, and J7:6.
- Manually clean the 3 overlapping-copper errors, then route the final 9 airwires.
