CRC/DRC Status Check
Worked for 26 mins 33 sec
Completed the low-voltage CT schematic compatibility fix and ran checks on both boards.
What changed on the linked low-voltage board:
- R2 is now a 100 Ω series current-limiting resistor, not a CT burden.
- Added D3 BAT54S clamp protection:
- D3 pin 1 → GND
- D3 pin 2 → 3V3
- D3 pin 3 → CT_SENSE_CLAMP
- Final CT path:
- J5 pin 1 → CT_SENSE_RAW → R2 → CT_SENSE_CLAMP → U4 +
- J5 pin 2 → CT_REF → R3/R4 midpoint → U4 -
Review results:
- Current power-board project: clean, no open ERROR/WARNING/OPEN/UNCERTAIN issues.
- Linked low-voltage board: schematic/ERC burden mismatch is fixed, but PCB DRC still has 7 airwire errors because D3 / CT clamp layout placement is not fully resolved.
Open items:
- Low-voltage board needs D3 physically placed near U4/R2 and the CT clamp/reference airwires routed.
- Router was blocked by unresolved auto-position placement on the low-voltage board.
Suggested next steps:
- Open the low-voltage board PCB and manually place D3 near U4/R2.
- Route CT_SENSE_RAW, CT_SENSE_CLAMP, CT_REF, D3 3V3, and D3 GND.
- Re-run DRC on the low-voltage board until the 7 airwires clear.
- Then run a final cross-board manufacturing validation.
Estimated time saved vs. manual EDA workflow: ~2–4 hours.

Tesla Coil Driver System Design Notes
Architecture Updates
- Project refactored toward a two-board Tesla coil system with separate hazardous-voltage power and low-voltage control partitions.
- Power-board mains input/protection stage was added with first-pass fuse, MOV, NTC, EMI filter, and bleeder network.
- Hazardous-voltage placement was optimized and a rollback point was documented before placement cleanup.
Manufacturing Cleanup
- Replaced generic protection clamp parts LED1 and LED2 with real library parts: SMAJ5.0A-TR.
- Both parts now use SMA package library components with manufacturer metadata and datasheet association.
- Original net connectivity was restored exactly after replacement:
- Purpose remains unchanged: fast clamp/protection around the gate-drive path.
