《XCircuit》是开放源码计划的免费线路绘图软体。 除了可画出高品质的线路图（PostScript格式）供出版用以外，程式可产生供SPICE用的线路网清单（netlist）。

　　启动之后发现界面很象一个画图软件,工具栏右边发现有一个图标,点击就看到元件了,就可以拖出来画图了....可以保存成eps格式的,直接插入tex就好了,质量号称是出版级的。

　　XCircuit is a UNIX/X11 (and now Windows, if you have an X-Server running) 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.
