XCircuit is a UNIX/X11 program (realeased since 3.6.0 version with Artistic License) for drawing publishable-quality electrical circuit schematic diagrams and related figures, and produce circuit netlists through schematic capture. XCircuit regards circuits as inherently hierarchical, and writes both hierarchical PostScript output and hierarchical SPICE netlists. Circuit components are saved in and retrieved from libraries which are fully editable. XCircuit does not separate artistic expression from circuit drawing; it maintains flexiblity in style without compromising the power of schematic capture. There are drawing programs, and there are schematic capture programs. All schematic capture programs will produce output for inclusion in publications. However, these programs have different goals, and it shows. Rarely is the output of a schematic capture program really suitable for publication; often it is not even readable, or cannot be scaled. Engineers who really want to have a useful schematic drawing of a circuit usually redraw the circuit in a general drawing program, which can be both tedious and prone to introducing new errors. XCircuit is flexible enough to be used as a generic program for drawing just about anything, and is competitive with powerful programs such as xfig. It is especially good for any task requiring repeated use of a standard set of graphical objects, including architectural drawing, printed circuit board layouts, and music typography.
