Started: Use the @bom tool to identify components lacking a "Manufacturer Part Number" and edit each such component to set its "Manufacturer Part Number" property to an appropriate MPN.

Work completed
  • All schematic errors resolved and verified by ERC: common ground, Q2 high-side switch stage, op-amp rail/input network, 3.3 V/EN RC network, buck converter net corrections, CAN transceiver termination.
  • Through-hole parts replaced with SMT footprints; all passives and regulators updated.
  • PCB layout prepared: 4-layer stackup with inner GND/12 V planes, PWR_HC netclass (PROTECTED_12V_BUS, F1_OUT) assigned 10–20 mil width at 2 oz, copper pours and stitched vias added for GND and 12 V.
Remaining actions
  • Component placement on the PCB (Auto-Layout placement agent)
  • Full net routing (Auto-Layout routing agent)
  • Assign any missing SMT footprints flagged in layout
  • Verify MPNs and part availability for manufacturability
Success criteria
✅ Schematic-level ERC checks pass with all critical errors fixed
✅ THT→SMT conversion and correct footprints assigned
✅ EMI-optimized copper pours and power trace requirements met
ℹ️ Layout DRC now limited to placement/routing – airwires eliminated at netlist level
Next step
Proceed with Auto-Layout placement and routing in the PCB editor, then run full DRC to finalize the design.
