The CircuiTikZ package for the graphical drawing of circuits was largely developed at the Chair of Technical Electronics. In recent years, CircuiTikZ has become the quasi-standard for documenting circuits in LaTeX.
In recent months, intensive work has been carried out on a new graphical user interface (GUI) for CircuiTikZ. This will be greatly expanded in the coming months, but is already available.
