Hi @User, I'm having trouble getting this working on my schematic. The example you provided works perfectly, and I've been copying from it to try and get mine to work but without success as of yet. The picture below is my top level schematic which saves only the operating point and nothing else (netlist and raw files attached). I have an

ngspice_get_value.sym

as shown, and an

ngspice_probe.sym

, and these are both at the top level. Simulation completes successfully and I then click on my "Backannotate" launcher which contains the following

name=h2
descr=Backannotate
tclcommand="ngspice::annotate"

Bit the probes still only show a

?

. Do you know what I may be doing wrong? Thanks in advance!
