7/7 Run placement/DRC review and report readiness before routing

Completed 11 design checks — found 198 issues.

Resumed and saved progress.
Completed:
Current status:
  • Placement has no overlap/out-of-bounds issues.
  • Remaining review errors are expected unrouted connections because routing has not started yet.
  • One important note: ESTOP is implemented on PC6 because PB11 is not exposed on the STM32F446RE LQFP64 symbol.
Ready for the next phase: route the PCB traces. Want me to go ahead?

Route pcb

Thought for a moment

I’ll route the PCB now. First I’ll check the board is ready for routing, clean up any blocking issues if needed, then run routing and review the result.

3/5 Run PCB routing

Thought for a moment

Pre-route validation says the board is structurally valid. There is one warning about a 3.3V connection at the STM32 VBAT pin being tight for the default track width, so I’ll proceed with routing and then inspect any leftovers.

Auto-routing your board.

Thought for a moment

The routing job failed to start due to a platform-side network/start error, not a board validation failure. I’ve reported it and will retry once before stopping.
