LTspice: How to convert .asc file to netlist?

Question

Using LTspice I can create .asc files which contain the information about my circuit. Is there a way to convert this information to a netlist? I am looking for a way to create a component and then add it to the library. I can use a text-editor to write it directly and then save it as a .lib file. However for more complicated circuits I would like to use the LTspice GUI and to create such components. Converting .asc to netlists would be a way I can think of. Any relevant ideas are appreciated.

Answer 1

Under the View menu option there is an entry called "SPICE Netlist" which creates a popup window where you can copy the text you want. You can also go into the File menu option and select New Symbol to create symbols you can associate with the .lib files you create, to provide a pretty image to go along with it. (You do need to match up pins and watch out for grounds.)

There is a very good group that can directly answer all these questions and more at LTspice group on Yahoo groups.

I have also written a schematic parser that can read up the LTspice schematics. I wrote it to generate ASCII schematics automatically from these files. It could be adapted to prepare a net list. But I think the LTspice program itself does enough already. Unless I misunderstood your goals.
