PCB Re-layout Routing


I’ll move only the FPGA passives blocking U3’s camera-pin sides, keep their electrical groups intact, then rerun DRC and routing feasibility without routing.
Moved FPGA decoupling capacitors C19–C29 outward to open the camera-pin fanout corridors and removed nine resulting stale traces.
  • All CAM1/CAM2 U3 pins now pass routing feasibility
  • No blocked camera nets
  • Overlaps, dangling traces, and outside-board components: 0
  • Board-wide airwires: 170
  • Only the informational exposed-pad via advisory remains
Route all remaining J2/J3 camera signals to U3, then run DRC.
I’ll route all remaining J2/J3 camera signals to U3 through the newly opened fanout corridors, then run DRC and report exact residual camera airwires or advisories.
Routed four additional camera connections:
  • CAM1_XCLK_SRC
  • CAM2_XCLK_SRC
  • CAM1_PCLK
  • CAM1_VSYNC
Blocked after two attempts: CAM2_PCLK, CAM2_VSYNC, and CAM1_HREF; remaining camera buses were not safely reachable. DRC shows 0 overlaps, dangling traces, invalid layers, or outside-board components. Board-wide airwires decreased to 166.
