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.
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.
