How to generate a symbol from a subcircuit file?

[medwatt]

I have the following subcircuit.

* Subcircuit

.subckt my_capacitor p n
C1 p n 1n
.ends my_capacitor

Pressing F9 to create a symbol does not create ports.

This approach doesn't work for SPICE models. Refer to the documentation for the proper solution: https://qucs-s-help.readthedocs.io/en/latest/SubLib.html#using-manufacturers-component-data-libraries The documentation describes OpAmp example.

There are two devices that allows to attach SPICE models:

• SPICE file
• SpiceLibComp -- for the whole library reference

The SPICE file device is more preferable. This device could be wrapped in a Qucs subcircuit and then library could be generated.
