I have an opamp .cir file that I want to add to my LTSPice library.

How do I proceed to do so? Which are the steps?

:cir - am I right in assuming it is a PSPICE file? You cannot, as far as I know, directly read a PSPICE file into LTSPICE. You'll have to recreate the circuit in LTSPICE manually.
What you can import into LTSPICE is a netlist, see here, provided the netlist is LTSPICE compatible. Usually some tweaking may be required.

Hi everyone, I need to run a simulation on LTspice on the xor port 74HCT1G86 whose Spice model is available on the manufacturer website. What is dowloaded is a htc.cir file that containg multiple components of the same family. Obviously i am interested in simulating just one, following the tutorials I have understood that I have to create a new symbol starting from the netlist file. In particulat i managed to create the symbol but as I copy-paste the .subtsk on the .op Spice directive there is an error saying that a declared variable is not recognized. Is there a way to run a sort of main file that contains all the dependencies of the library? Thank you
