XCircuit is a UNIX/X11 program 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.
