Document Review and Assistance
Thought for 3 sec
I’ll route the PCB with priority on low-noise analog paths: short sensor-to-AFE/ADC connections, clean reference/power distribution, and separated digital control routing, then run airwire/DRC checks.
Worked for 24 mins 43 sec
I’m blocked now because the account has no available ACUs, so I can’t run the final post-route DRC/airwire verification.
Accomplished this session:
- Ran pre-route validation: board was routable with 51 PCB components / 47 nets.
- Auto-routed the board, adding 880 routing nodes.
- Found post-route issues: 2 airwires and 4 overlapping-copper errors, localized mainly around C15 GND plus GND connectivity near U9/U5.
- Removed two conflicting trace segments and ran one cleanup auto-route pass, adding 9 routing nodes.
Open items:
- Final DRC/airwire check still needs to be run once ACUs are available.
- If errors remain, inspect C15 GND pad / bulk capacitor footprint area first.
- Low-noise analog routing should be visually reviewed before fabrication, especially sensor → LMP91000 → ADC paths and the 2.5 V reference routing.
Suggested next steps:
- Re-run full post-route DRC and airwire checks.
- Fix any remaining localized C15/GND overlap issues.
- Review analog/reference routing quality manually before generating manufacturing files.
