PCB Design Revision
Worked for 4 mins 37 sec
Added power-source markers to the rails and renamed the rails:
- VCC now includes J4:VCC, U1:VCC1, J5:2, MEGA1:+5V_1, MEGA1:+5V_3, and the VCC power marker.
- VIN now includes J3:1, MEGA1:VIN, MEGA1:+5V_2, U1:VCC2, and the VIN power marker.
ERC result: the two previous “power input not driven” errors are cleared. One warning remains on PWR_VCC:P1 because the marker symbol has a physical terminal that ERC still treats as floating; it does not affect the actual VCC/VIN rail drive status.
Run ERC/DRC and list any remaining schematic issues.
Thought for 9 sec
I’ll rerun both schematic/ERC and PCB/DRC checks now, then list only remaining schematic-side issues separately from layout results.
Thought for 4 sec
I’m blocked from running the requested ERC/DRC because the session has run out of execution credits.
Current known state from the last completed checks:
- PCB/layout DRC was previously clean after routing cleanup.
- The earlier missing-power ERC errors on J4:VCC and MEGA1:VIN were cleared after adding VCC and VIN power-source markers.
- One known schematic warning remained: Floating pin: PWR_VCC:P1 on the power marker terminal. This appears to be a marker-symbol warning, not a functional rail issue.
What remains:
- Re-run ERC and DRC fresh when credits are available.
- Confirm whether PWR_VCC:P1 is still the only schematic warning.
- If desired, replace/adjust the marker implementation so the power-source marker itself does not create a floating-pin warning.
Fix PWR_VCC warning
Inspect power markers

Re-run later
