LED Blinker PCB Layout

The schematic is complete with 11 through-hole components and 8 nets, but PCB placement and trace routing remain unfinished; the existing DRC reports airwires, so both auto-placement and routing are needed.
I can’t run or apply auto-layout because the account currently has no available ACUs, so AI execution features are unavailable. Once ACUs are available, the next steps are: define/confirm the board outline, auto-place components, verify placement and clearances, auto-route all nets, then run DRC and remediate remaining violations.
The schematic is complete, but the PCB still needs both component placement and trace routing. No new layout changes were applied in this session because the account has no available ACUs, so auto-layout execution is unavailable.
Remaining work: confirm the board outline, auto-place the 11 through-hole components, route all 8 nets, and run DRC to resolve any remaining violations.
The PCB still requires both placement and routing: recent changes adjusted some component positions, but the board remains unrouted with airwires.
I couldn’t run or apply auto-layout because no ACUs are currently available. Remaining work is to finalize the board outline, auto-place all components, route the 8 nets, and run DRC.
