Started: verifying derating and running ERC checks.
Reading schematic for C1, C2, C3 and 13 more.
Running 5 design checks.

Set R1's Resistance to "50kΩ"
Set R2's Resistance to "31.6kΩ"
Thought
Work done
- Removed optional bulk capacitors: C4, C10
- Downsized passives (0201 preferred; 0402 kept where higher effective C is needed):
- Normalized passive properties (Capacitance/Resistance formatting, Package, Role/Role Details) on the above parts
Success criteria review
- ✅ Optional bulk capacitors removed: C4, C10
- ✅ Remaining passives migrated to smallest packages feasible (0201 where feasible; 0402 retained for the 10 uF “critical” caps)
- ✅ Existing net connectivity preserved (no net rewiring performed; caps/resistors remain on VIN, +1V2, +1V8, U2_VOUT_NEG, GND as before)
- ❌ ERC still flags “Missing Power” on U2, U3, U5 (this appears to be a pin-type/power-flag issue, not a disconnected net)
Next steps
- I can clear the ERC “Missing Power” by adding the proper power-driving flag/source on VIN (and any other rails ERC considers “inputs”). Tell me if you want me to add a power flag / power source symbol to the VIN net.
