Thought for a moment — Clarifying ground component identification

Task unable to complete.

Reading schematic details.
Work done
  • Audited the schematic ground structure and confirmed there are no explicitly named split ground domains such as AGND or DGND.
  • Verified the project contains one named GND net plus many unnamed local ground-class nets tied to IC ground pins.
  • Updated the Change Log to accurately record the audit findings and the modification attempt.
Success criteria review
  • ❌ All standard GND portals replaced with ground symbols
  • ✅ Explicit split ground domains such as AGND and DGND remain intact
  • ✅ Schematic integrity was reviewed enough to confirm no explicit split-ground domains were changed during the attempt
Next steps An issue occurred while applying the bulk ground-symbol replacement, so I could not complete the actual portal swap in this run. If you want, I can continue with a narrower, staged replacement strategy once the schematic edit path is working again.

Change Log
2026-04-16
  • Audited all ground-related nets and symbols in the schematic.
  • Confirmed there are no explicitly named split ground domains such as AGND or DGND in the current project.
  • Confirmed the project contains one explicitly named GND net plus multiple unnamed nets classified as ground (for example local PGND/GND pins on power ICs).
  • Attempted bulk replacement of standard GND portal instances with canonical ground symbols, but the batch rewrite did not apply due to an issue during schematic modification.
  • Verified that no explicit split-ground domains were altered during the attempt.
