ERC Summary for CT_Energy_Harvester_PMU
Critical Errors:
  • Overlapping Copper (51 errors): Multiple copper shapes are shorted together (e.g. GND vs HARVEST_IN, etc.).
  • Airwires (26 errors): Numerous nets (e.g. D3 net, U1:VIN to D3, etc.) have unrouted connections.
  • Layers with Multiple Fills (1 error): Conflicting copper fills on the same layer.
  • Missing Manufacturer Part Number (1 error): SUBLAYOUT1 (the LDO symbol) has no MPN assigned.
Warnings: None
Successes: Many nets correctly routed and parts have footprints.
Next Steps:
  1. Resolve copper overlaps by adjusting trace/fill shapes.
  2. Route all airwires.
  3. Assign an MPN to SUBLAYOUT1.
  4. Re-run ERC to ensure no remaining critical errors.
