Forum: Analog Circuits Multiple instances of "Vsn"

Some labels are not properly attached to the corresponding pin(s).

Circuit elements like C2 too, but this usually works without any error 
message.

You have to use "Edit-Label Net F4" instead of "Edit-Text 'T'" to assign 
net names.

The simulation runs at least w/o error messages after correction. You 
should verify the circuit anyway - Vout remains at Vpn constantly.
