Re: [Qucs-help] Add a library

[<Mic...@al...>]

Hello,

it is not neccessary to create these files with a text editor.
Indeed the format is not intented to be created this way.

The best way is the following:
Just create the component as a subcircuit and paint a nice
symbol for it (see online help). Then build a library from
that subcircuit with "Project->Create library..." from the
menu. Now a user library was created in "~/.qucs/user_lib/".
You can have look into it with a text editor if you like,
or just use it with the "component library" tool.

Have fun,
    Michael
