PCB Feasibility
Thought for 1 min 50 sec
PCB layout placement is done and ready for your review.
Accomplished:
- Resized the board to 260 × 180 mm with a 4-layer stackup.
- Placed all PCB components by functional block: high-current phases, control/ADC, auxiliary regulators, contactor I/O, CAN/JTAG, and edge connectors.
- Replaced U18 with the compatible TPS3431-Q1 variant because the original TPS3431SDRBR footprint had a blocking copper-overlap issue; I filed an internal part-quality report.
- Placement/pre-routing checks are now clean except for routing advisories that are expected and not blocking.
Open items:
- I stopped before routing at the normal placement-to-routing checkpoint.
- TPL9202 is still not suitable for real 24 V contactor coils; replace that driver approach before final PCB release.
- High-current power paths will need copper pours/bus geometry, not just thin auto-routed traces.
Suggested next steps:
- Review the component placement in PCB view.
- If placement looks good, tell me “route it” and I’ll start routing.
- After routing, run DRC/airwire cleanup and then review high-current copper widths/thermal areas.
Thought for 17 sec
I’ll route the PCB now: run the routing pre-check, set conservative trace-width priorities for power/control nets, auto-route the board, then review remaining airwires/DRC issues.
Worked for 33 sec
Routing could not continue because the account currently has no available ACUs, so AI layout/routing tools are unavailable.
Accomplished this session:
- Started the routing phase and prepared the routing checklist.
- Confirmed the intended routing flow: pre-check → set routing rules/width priorities → auto-route → DRC/airwire cleanup.
- Loaded the routing/remediation procedures needed for the next step.
Open items:
- Run routing pre-check again.
- Set power/control routing widths and priorities.
- Run the full-board auto-router.
- Review and fix remaining airwires/DRC issues.
- Add high-current copper/pour strategy after initial routing; auto-routing alone is not sufficient for the 40 A power path.
Suggested next steps:
- Add ACUs to the account.
- Then send “continue routing” and I’ll resume from the routing pre-check.
