I couldn’t analyze or modify the PCB because no ACUs are currently available, so the existing placement and routing remain unchanged.
Remaining work:
- Inspect the board for unplaced components, airwires, routing completeness, and DRC issues.
- Run auto-placement if placement needs improvement.
- Run auto-routing if unrouted nets remain.
- Apply the changes and verify the final board with DRC.
Add ACUs, then repeat this request to complete the auto-layout.
