The correction-and-routing executor was launched with placement locked and the required sequence: fix U1’s TPS259470 footprint, clear its duplicate-pad DRC errors, then selectively route the protected 5 V, 3.3 V, USB, and LED-current nets.
Open items
The executor has not produced a completed report.
I cannot confirm whether any footprint or routing mutations landed.
Fresh DRC, USB pair matching, and connectivity verification remain outstanding.
Execution is paused because no ACUs remain.
No routing result should be treated as verified until the executor report and live board are reconciled after ACUs are restored.
Received notification from "TPS259470 Footprint Routing" that it finished — picking the work back up.
All 113 component footprints received board positions.
No routing
Completed
No routing tool was called. Project history after the pre-placement baseline contains only rewriteLayoutComponentPlacement / live-update commits; inspected affected paths are component placement rule sets, not standalone trace/via/route paths.
Placement checks and iteration
Completed with two justified footprint-internal DRC artifacts
Real placement-induced copper collisions were cleared; final placement/bounds/keepout checks are clear.
Routing-feasibility check
Completed
Current layout summary reports routing congestion as clear: enough space is available for traces. No traces were added.
Component-side counts
Top: 49 components
Bottom: 64 components
Total: 113 components
Every Bottom-side component is a resistor or capacitor; all connectors, ICs/modules, inductors, protection devices, LEDs, buttons, test points, and mounting holes remain on Top.
Major block locations
Coordinates use the board-center origin in millimeters.
ESP32 / boot-reset: U3 at (-6.0, 19.04) on the top edge, antenna facing outward. The module intentionally extends into the top antenna-overhang zone. SW1 is upper-left of U3; SW2 is at (-23.3, 8.0). C13/C14/C15 and pull/RC parts are placed around the module.
Main power and 3.3 V buck: J1 at the left edge (-37.4, -4.0); D1/U1 immediately inward around x=-32 to -27; U2/L1 at (-17.0, -8.0) and (-16.5, 0.2) with power capacitors/passives clustered on Bottom in the left/lower-left region.
Native USB data: J2 at the bottom edge (-12.0, -22.1); D2 at (-2.5, -12.0); U6 at (4.8, -4.0); USB source resistors are on Bottom near the U3 side of the corridor.
On-board/remote IMU: U4 at (7.5, 10.0) in the quiet upper-center sensor area. C17/C18/C19 are on Bottom adjacent to it. J3 is on the bottom-right edge at (25.0, -21.8) with D3/D4/D5 and series protection in the lower-right corridor.
ToF interface: J4 at the right edge (36.6, 1.5); D6 and D9 are immediately inward at (31.5, -1.5) and (33.5, 9.3).
LED driver: U5 at (24.0, -8.0); J5 at right edge (37.1, -10.65); J9 at (35.45, -17.4). R34/R35 and C20-C22 are clustered around U5 on Bottom.
Headers: J6 bottom-left at (-19.5, -23.42); J7 lower-center-right at (15.0, -11.2); J8 upper-right at (20.2, 13.0).
Test points: all 16 are on Top and distributed around accessible perimeter/functional-block positions.
Verification evidence
Placement and feasibility
Final autonomous-placement pass: 0 component-body overlaps and 0 keepout-spacing violations.
Board: 80 x 50 mm, four copper layers, rounded 2 mm corners.
Layout summary: 113 elements; routing congestion analysis states that routing space is available throughout the board.
Formal review did not return component-body-overlap, protected-intrusion, component-outside-board, or edge-placement errors in the requested error/warning filter.
Overlapping-copper closeout
Two real placement-induced copper collisions were cleared without routing:
M1 plated mounting-hole pad vs TP3 pad — moved TP3 from approximately (-36, 18) to (-36, 16.5). The original DRC pair was 1488476f-...__dd36a631 (M1's 6.5 mm plated center pad) vs b7d0eb69-...__8dac37d6 (TP3 pad).
J6 Pin_6 vs M2 plated mounting-hole pad — moved J6 from approximately (-21.3, -23.42) to (-19.5, -23.42), preserving 270° rotation and bottom-edge access. The original pair was 2eb2e17d-...__a1a1a132 vs fe3c2186-...__dd36a631.
Moving TP3 created a temporary body overlap with status LED D7; D7 was shifted within the same upper-left status area to (-31.5, 15), and the overlap then cleared.
Fresh DRC now returns only two U1 footprint-internal overlapping-copper findings:
DVDT / DVDT_2 — 930e8929-...__2130897f vs 930e8929-...__a1102636.
EN/UVLO_2 / EN/UVLO — 930e8929-...__a6cedaa8 vs 930e8929-...__ee0b1f33.
These are justified library-footprint artifacts, not board-level shorts:
The official TI datasheet identifies the device as RPW, VQFN-HR, 10 pins and lists only pins 1–10. DVDT is pin 7 and EN/UVLO is pin 1.
The Flux part incorrectly exposes 14 schematic terminals. Terminals 11–14 (ITIMER_2, EN/UVLO_2, PGTH/~FLT_2, DVDT_2) are marked no-connect in this project.
The footprint's _2 pads intentionally overlap/touch the matching outer lead geometry from TI's segmented RPW land pattern, but the _2 pads have no effectiveNetId. The connected outer pads correctly carry EFUSE_DVDT and EFUSE_UVLO.
Therefore DRC interprets the unnetted duplicate copper as a different-net overlap even though it represents one physical package lead. Moving U1 cannot resolve it, and changing the footprint geometry would risk violating TI's recommended land pattern.
No footprint edit was made. The correct library repair is to model the RPW device as 10 electrical pins and assign each segmented copper shape for pin 1 and pin 7 to the same terminal/net.
Autonomous-placement advisory residue
The final placement engine also reported advisory/internal items that are not current formal DRC errors:
2 bounds flags: identified by the placement engine as U3/J8. U3 is the intentional antenna overhang; J8's reported body coordinates are inside the board, so its item appears to be an edge-policy/advisory classification rather than a physical outside-board body.
2 “unplaced” flags: the engine did not return designators, while direct layout inspection confirms coordinates for all 113 components.
29 net-grouping advisories and 1 orientation-consistency advisory.
64 layer-policy advisories: these correspond to the 64 Bottom components, but direct inspection confirms all 64 are permitted resistors/capacitors; no forbidden part type is on Bottom.
Final status
Placement-induced copper collisions: 0 remaining. Formal DRC still displays the two justified U1 footprint-internal artifacts above; they require a library-part terminal/pad-mapping correction, not board routing or component movement. No traces were added and no net was routed.
