Implementing custom symbol/component libraries

[georgtree]

Hello!
Question is simple - what is the right way to implement custom library with custom symbols, connected libraries and deep hierarchy in Qucs-S?
Where to find the format description (assume some XML ?), how properly create links to libraries, etc.
Thank you in advance.

The procedure of the libraries creation is not documented. It is planned to include this in a new documentation. See #554 In a short words you should create a project containing subcircuits and the use Project->Create library menu entry. The take the library file from $HOME/.qucs/user_lib Wrap SPICE netlist in a subcircuit using spice netlist device. Don't use SpiceLibComp, because it will not embed the SPICE code in XML file. Normally you do not edit the XML yourself with the text editor. The full procedure of the library creation and XML syntax are beyond the scope of answer in github issue.
