Circuit components are saved in and retrieved from libraries which are fully editable. XCircuit regards circuits as inherently hierarchical, and writes both hierarchical PostScript output and hierarchical SPICE netlists. The link to XCircuit for OS-X is: package xcircuit. XCircuit is a program for drawing publishable-quality electrical circuit schematic diagrams and related figures, and produce circuit netlists through schematic capture. XCircuit: Quick Start The frames version of the XCircuit website has a number of menu items down the left side.
