Gerbvは、オープンソースのガーバーファイル (RS-274Xのみ)ビューアです。Gerbvは、いくつかのファイルを読み込み、画像等で表示することができます。ガーバーの閲覧を行うだけでなく、pick-placeファイルと同様にExcellon drillファイルとして表示することもできます。

ImageMagickはコマンドラインインタフェースやプログラミングインタフェースから様々なフォーマットの画像の作成/編集などができるフリーソフトウェアです。画像の一部を取り出したり、リサイズしたり、組み合わせたり、特殊効果を適用したり、文字を加えたりポリゴンや曲線を追加したりできます。

Qucsは、グラフィカルインターフェースを備えた回路シミュレータです。 このソフトウェアは、あらゆる種類の回路シミュレーション、例えば直流、交流、Sパラメータ、トランジェント、ノイズや高調波平衡解析などをサポートすることを目指しています。 純粋なデジタルシミュレーションもサポートされています。

gEDA is a suite of electronic design automation (EDA) tools. Currently, the project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.

FidoCadJ is a very easy-to-use editor, with a library of electrical symbols and footprints (through hole and SMD). Drawings can be exported in several graphic formats (PDF, EPS, PGF for LaTeX, SVG, PNG, and JPEG). Although very simple and not relying on any netlist concept, FidoCadJ can be considered a basic electronic design automation program. FidoCadJ uses a file format containing only UTF-8 text, which is very compact and suited for copying and pasting with newsgroups and forum messages. This determined its success, as it is quite versatile for simple mechanical drawings as well as for electronics.

Gnu Circuit Analysis Package is a general purpose circuit simulator. It performs nonlinear DC and transient analysis, fourier analysis, and AC analysis. Spice compatible models for the MOSFET (level 1- 7) and diode are included. This project is not based on Berkeley Spice, but some of the models have been derived from the Berleley models. It was formerly known as 'Al's Circuit Simulator'.

Electric is a complete EDA system that can handle many forms of circuit design, including Schematic Capture (digital and analog), Custom IC layout, Logic Simulation, Electro-mechanical hybrid layout, Programmable logic (FPGAs) and much more.

Qucs is a circuit simulator with a graphical user

1. It aims to support all kinds of

circuit simulation types, including DC, AC, S-parameter, and harmonic balance analysis.

GTKWave is a wave viewer for Verilog simulation. The viewer supports execution of Tcl scripts and enhanced Drag and Drop operations.

XCircuit is a UNIX/X11 program for drawing publishable-quality electrical circuit schematic diagrams and related figures, and producing 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.

Oregano is an application for schematic capture and simulation of electrical circuits. The actual simulation is performed by SPICE, which is required for simulation, but not necessary to run the application.

Gerber Viewer is a viewer for Gerber files, also called RS274X. It lets you load several files on top of each other, do measurements on the displayed image, etc. Using Cairo makes it possible to export Postscript and PDF files.

TkGate is an event-driven digital circuit simulator with a TCL/Tk-based graphical editor. It supports a wide range of primitive circuit elements and user-defined modules for hierarchical design. The distribution comes with a number of tutorial and example circuits which can be loaded through the "Help" menu, and the example circuits include a simple CPU, programmed to run the Animals game. TkGate has multi-lingual support for English, Japanese, French, German, Spanish, Welsh, and Catalan.
