I chose one potentiometer from the all_files folder. But still I am unable to simulate my circuit if I use this component in my circuit. Same error message appears again - "Unknown sub-circuit called in: x001 n003 n008 nc_01 potentiometer rtot=50K wiper = 5"".
I haven't used the Potentiometer models so I can't say with certainty. ?But the one you picked is a subcircuit. ?(That might be true of all of them.) ?It is not only a symbol. ?You must also import or include the subcircuit definition. ?In the case above, it is looking for a subcircuit definition named "potentiometer", and it can't find it.
Check where you found the symbol and look for a subcircuit model that goes with it. ?The subcircuit model should begin with the line
.SUBCKT potentiometer ...
followed by other stuff. ?You can either call it with an .INCLUDE statement, or paste it directly into your schematic.
