@Stefan Schippers, I am trying to annotate the current , other parameters in schematic using back annotation command : xschem annoate op but annotation is not happening? is this issue with xschem version? Can you tell which version of xschem i need to update. I am using xschem version: XSCHEM V3.1.0

for annotation in the schematic to work you need to do a

.op

command followed by a

write xxxx.raw

where

xxxx

must be the same name as the circuit. If you are simulating

opamp.sch

then save simulation operating point with

write opamp.raw

usually you should do:

.options savecurrents
.control
  save all
  op
  write xxxx.raw
.endc
