Power-pin net mapping (as currently wired)
Table
| IC | Pin | Pin # | Net it’s on | Notes |
|---|---|---|---|---|
| U2 | VIN | 3 | ^+12V | Net currently only shows U2:VIN connected. |
| U2 | GND | 1 | ^CHASSIS | This is why ERC reports a single-pin net for ^CHASSIS. |
| U3 | AVDD | 4 | ^+3V3 | Only pin 4 is connected to ^+3V3 right now. Other AVDD pins are not on this net. |
| U3 | AVDD | 8 | (unconnected) | Not on any net. |
| U3 | AVDD | 11 | (unconnected) | Not on any net. |
| U3 | AVDD | 15 | (unconnected) | Not on any net. |
| U3 | AVDD | 17 | (unconnected) | Not on any net. |
| U3 | AVDD | 21 | (unconnected) | Not on any net. |
| U3 | VDD | 28 | (unconnected) | Not on any net. |
| U3 | GND | 29 | (unconnected) | Not on any net. |
If you want, I can also list the AGND pins for U3 (there are several) and what nets they’re currently on, since those are part of the power/return path.
List U3 AGND nets
Check missing decoupling
Inspect U2 output net
Find U3 power pins
