Work done
  • Set the layout to 90 mm x 60 mm and applied a 4-layer stackup with the required inner-plane structure intent: Top signal / L2 GND / L3 power plane / Bottom signal
  • Applied baseline layout rules for 5 mil signal routing and preferred widths for 20 mil power and 40 mil battery/charge paths
  • Reviewed the current schematic/layout state and confirmed the project already contains the major functional blocks, including IC1, IC2, U1, U2, U3, IC4, J1, and J4
  • Checked validation state: all footprints exist, but the layout still has 91 airwire errors, so routing is not complete
Success criteria review
  • ✅ Board dimensions are set to 90 mm x 60 mm
  • ✅ Board is on a 4-layer stackup with the required plane assignment intent
  • ❌ Block placement constraints were not enforced for RF, LTE, GNSS, MCU, SWD, power, audio, and USB-C sections
  • ❌ Advanced routing rules were only partially applied; I could not implement placement-aware constraints such as GNSS no-copper zones, RF no-via paths, stitching-via fences, SPI length matching, or decoupling proximity enforcement
  • ❌ Post-route verification does not pass: the board still has 91 airwires, so it is not fully routed
Next steps I’m blocked because the required placement/autorouting mutation capability was not available in this run, so I could not move components or complete routing. If you want, I can continue next by generating a precise placement and routing checklist for the existing parts around IC1, IC2, U1, and U2, or resume as soon as placement/routing actions are available.
