I get this error when I press "netlist" Error: undriven node: #net1 I'd like to find where net1 is, since it's not labeled on the schematic right now. Clicking on the wire just reveals the name of the pin I assigned the node to. How can I find where net1 is?

In xschem, go to the 'view' menu, 'show/hide', enable 'show hidden texts'. That should add net labels to the pins of most components

Hi, I checked the "View" settings and found the option already enabled. Attached is my schematic (it shows a question mark on the drain terminal, perhaps that's relevant) (pdk used here is sky130)

Just looking at the screenshot here, you may want to connect the substrate of M1 (the B pin)

A useful command is this:

xschem instances_to_net {#net1}

It will return something like this:

{ {m5} {b} {690} {-290} } ....

If there are more instances attached multiple items will be returned The first sub-item is the instance name, followed by the pin name attached to the specified #net1, The last two numbers are the coordinates so you can locate the instance(s) involved.

Ah, thank you for the detailed explanations, the problem was indeed with body terminal which I forgot to ground (as was confirmed by the command)
