Objective
Report-only verification that the Bottom GND polygon exists and behaves correctly. Do not modify the design.
Scope (STRICT, NO EDITS)
  • Do NOT create, move, or edit any object.
  • Do NOT start routing or place polygons/zones.
  • REPORT ONLY.
Tasks
  1. Polygons inventory
    • List all polygons/fills with: • Layer • Net • Approx. area (if available)
    • Confirm there is at least one polygon on Bottom layer tied to GND.
  2. Connectivity spot-check (report-only)
    • For these GND pads, report whether they have thermal/solid connections to the Bottom GND polygon: • J24V_IN:GND • D1 (TVS):GND • U1 (buck): GND pad • U2 (3.3 V LDO): GND/EP • J_SDCARD: shield GND
    • If thermal spokes cannot be programmatically detected, state “unable to auto-detect” and just report whether the GND polygon touches those pads.
  3. Targeted DRC (categories only; no edits)
    • Run/check these categories and summarize counts: • Floating/Isolated copper (islands) • Overlapping fills / polygon overlaps • Protected intrusions (keep-out violations) • Clearance violations (global)
    • If any violations remain, list each with: • Category • Object(s) • Coordinates or reference • One-line hint on what to adjust manually
  4. Crystal keep-out confirmation
    • Report if any keep-out rules/zones are present around the crystal loop (Y1, C15, C16).
    • If present, confirm the Bottom GND polygon is not filling inside that keep-out.
  5. Suggested GND stitching via spots (TEXT-ONLY)
    • Suggest 3–6 coordinates or reference-near spots where stitching vias would most help (buck GND loop, TVS/J24V_IN GND, LDO GND/EP, SD shield corners).
    • Do not place vias; suggestions only.
Output format
Return a concise checklist:
  • Polygons found (layer/net/area)
  • GND polygon on Bottom: YES/NO
  • GND contact at key pads: per pad YES/NO (or “undetected”)
  • DRC summary: counts per category + short list of remaining items
  • Crystal keep-out: present YES/NO; fill inside keep-out YES/NO
  • Suggested stitching via spots: bullet list (text-only)
Important
This is a verification pass. DO NOT queue actions or start long plans. If any step is unsupported by the API, say so and continue with the rest.
