I’ll inspect the schematic/netlist for unconnected power pins, map each IC/module power pin to the intended rails, apply the needed wiring fixes, then run validation to catch remaining power/ERC issues.
Initial inspection found the IC supply pins already assigned to the expected rails; I’m making one focused power-net cleanup pass on rail metadata and the relay coil return so the power intent is explicit.
Power-net review and wiring cleanup is complete. I marked the main rails as Power/Ground, verified U1/U2/U3/U4/U5 supply pins are connected to their expected rails, and connected K1/K2 relay coil NEG return to AGND.
Open items:
K1/K2 relay coils are now tied from +5V_RELAY to AGND, so they will be continuously energized unless you intended to add switching control.
Suggested next steps:
Add transistor/MCU relay drivers if the relays should be controllable.
Review decoupling capacitor placement near each IC power pin.
Proceed with layout/routing checks for the updated power nets.
