DOGS Placement Eval Run

Thought for 2 sec

The placement pass is complete: all 130 parts are inside the board with no reported overlaps, bounds, keepout, edge, or switching-stage findings. I’m independently checking the result and final design-review status before closing.

Independent review found three local bypass/bootstrap refinements: C28 at U2 and C22/C38 at U6. The edge connectors are correctly aligned to the board edge and intentionally overhang mechanically; I’m applying those three fixes and re-running explicit placement checks.

"PCB Placement Complete" completed.

Worked for 1 min 10 sec

flux

All 130 components are placed on the 100 × 100 mm board. U2/U3/U5/U6 power stages are compact, including corrected placement of bootstrap/bypass capacitors C28, C22, and C38.

Open items

182 airwires remain, as expected before routing.
Edge connectors intentionally overhang the outline while their edge rules remain aligned.

Suggested next steps

Configure power-net widths and copper zones.
Route the switching stages first.
Route remaining signals and run full DRC.
Clean up silkscreen and test-point labels.

Silkscreen Association Cleanup

Result: partial completion, not final silk signoff

Only three SVG path d attributes were changed in the existing Top silkscreen asset; asset identity and all other artwork were preserved. No component-position, footprint, board, stackup or electrical mutation was issued.

Table

Requested reference	Edit status	Result / blocker
R36	Completed	Horizontal at world center (-7.55,16.40) mm, to the right of its own footprint. Geometric verification passed; visual acceptance pending.
C34	Completed	Horizontal at (-7.75,15.20) mm, right of its footprint, below R36 reference. Geometric verification passed; visual acceptance pending.
R29	Completed	Horizontal at (0.00,11.90) mm, upper-right of its footprint. Geometric verification passed; visual acceptance pending.
R4	Failed to resolve; unchanged	No verified adjacent location satisfying occupied-footprint, neighboring-label and own-side constraints. R3/U1 and neighboring divider parts constrain available space.
R30	Failed to resolve; unchanged	Interior divider row has narrow surrounding gaps between U1, R4/R32 and R31. No verified clear adjacent location found.
R32	Failed to resolve; unchanged	Nearby C3/R33 and existing C29/R33 references constrain side/below placement. No verified clear adjacent location found.
R19	Failed to resolve; unchanged	Adjacent U6, R14 and C20/C21 constrain placement; existing R15 reference occupies the useful right-side region. No verified clear adjacent location found.
R31	Failed to resolve; unchanged	Divider-row gaps and existing C35 reference constrain adjacent locations. No verified clear adjacent location found.

The unresolved items are not proven physically impossible: a conservative AABB search with 0.15 mm clearances, 0/90-degree text, 0.8/1.0 mm height and <=0.5 mm own-footprint gap found no accepted candidates for them. Do not treat search failure as permission to shrink text below requirements, move components, or silently relocate references outside the eight-item scope. Further manual/local geometry work is needed.

Applied geometry and evidence

All three edited labels use uniform X/Y centerline scaling 0.65/0.85, giving 0.80 mm stroke-inclusive character height with 0.15 mm stroke; orientation 0 degrees. Source byte verification found changes exclusively in those three path attributes.

Table

Label	Own occupied-footprint gap	Minimum other-reference clearance
C34	0.22353 mm	0.240 mm to C7
R36	0.42353 mm	0.430 mm to R9
R29	0.27353 mm	0.300 mm to R31

All 369 comparisons against 123 unchanged reference/legend paths passed without stroke or bounding-box intersection. Thirty local component-box comparisons passed. Occupied body/pad AABBs were used conservatively; this is not an independent courtyard/CAM signoff. No routing or PCB-net regeneration was attempted.

Verification and visual blocker

Placement checks rerun at 2026-09-15T15:36:15.170Z returned zero selected errors and the same six switching-power-stage warnings as baseline (U2 input/switch detours and U3/U5 inductor detours). These warnings were deliberately not remediated in this silk-only task.

Pre- and post-edit layout raster views were requested and inspected. They remain malformed: giant black diagnostic text boxes and white silk on a white background prevent reliable local reference reading. The browser editor focus also failed because no requester frontend session was found. Numerical/source validation therefore must NOT be described as visual confirmation.

All eight labels are NOT confirmed unambiguous. Five remain unresolved, and final visual signoff for the three edited references is blocked. No assigned item was silently marked successful on placement checks alone.
