《XCircuit》是開放源碼計(jì)劃的免費(fèi)線路繪圖軟體。 除了可畫出高品質(zhì)的線路圖（PostScript格式）供出版用以外，程式可產(chǎn)生供SPICE用的線路網(wǎng)清單（netlist）。
　　啟動(dòng)之后發(fā)現(xiàn)界面很象一個(gè)畫圖軟件,工具欄右邊發(fā)現(xiàn)有一個(gè)圖標(biāo),點(diǎn)擊就看到元件了,就可以拖出來(lái)畫圖了....可以保存成eps格式的,直接插入tex就好了,質(zhì)量號(hào)稱是出版級(jí)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.

圖是XCircuit啟動(dòng)后之使用介面圖,在 XCircuit 介面之最上方是基本操作選單如檔案 (File),編輯 (Edit),文字 (Text),選項(xiàng) (Options),視窗 (Window) 與網(wǎng)表 (Netlist) 等,而在此介面之最右側(cè)為基本工具圖示如繪制矩形 (draw box),繪制弧形 (draw arc) ... 等.至於在 XCircuit 介面之最下方則是一些編輯 態(tài)之 位,接下我們將針對(duì)基本工具進(jìn)詳細(xì)之明.
