Stripboard Magic is a Windows application for designing PCB layouts on stripboard (aka prototyping board). It was released by a British company called Ambyr which ceased trading a long time ago.
The interface is a quite primitive and a little strange but the program is functional even on Windows XP. It also works great under wine in Linux, at least with version 0.9.38 and above.It should probably work on older versions too.source
TINA Design Suite is a powerful yet affordable software package for analyzing, designing and real time testing analog, digital, VHDL, MCU, and mixed electronic circuits and their PCB layouts. You can also analyze RF, communication, optoelectronic circuits, test & debug microcontroller applications. A unique feature of TINA that you can bring your circuit to life with the optional USB controlled TINALab II hardware which turns your computer into a powerful, multifunction T&M instrument. Electrical engineers will find TINA an easy to use, high performance tool, while educators will welcome its unique features for the training environment.
Easy to use schematic entry. Enter any circuit within minutes with TINA’s easy-to-use schematic editor. Enhance your schematics by adding text and graphics elements such lines, arcs arrows, frames around the schematics and title blocks. Choose components from the large library containing more than 20,000 manufacturer models. You can check schematics for errors with TINA’s advanced ERC functions. The schematic editor supports complex hierarchical designs, team design and version control.
Powerful analysis tools. Analyze your circuit through more than 20 different analysis modes or with 10 high tech virtual instruments. Present your results in TINA’s sophisticated diagram windows, on virtual instruments, or in the live interactive mode where you can even edit your circuit during operation, develop, run, debug and test VHDL & MCU applications.
Integrated PCB design. The new fully integrated layout module of TINA has all the features you need for advanced PCB design, including multilayer PCB’s with split power plane layers, powerful autoplacement & autorouting, rip-up and reroute, manual and ”follow-me” trace placement, DRC, forward and back annotation, pin and gate swapping, keep-in and keep-out areas, copper pour, thermal relief, fanout, 3D view of your PCB design from any angle, Gerber file output and much more.
Advanced presentation tools. Make stand-out reports and presentations of schematic diagrams, annotations, formulas provided by symbolic analysis, Bode plots, Nyquist diagrams, poles and zeros, transient responses, digital waveforms, and other data using linear or logarithmic scales. Customize presentations using TINA’s advanced drawing tools to control text, fonts, axes, line width, color and layout. You can create, edit and print documents directly inside TINA or cut & paste your results into your favorite word processing or DTP package.source
PCB is a printed circuit board design program that was written by Thomas Nau from the University of Ulm in Germany. The program is currently being maintained by Harry Eaton at the Johns Hopkins University Applied Physics Laboratory. PCB is distributed under the GNU General Public License (GPL). This article will demonstrate the use of PCB by making a circuit board from the microphone preamp circuit shown in the LWN feature article on Xcircuit . Pcb allows you to produce custom prototype quality circuit boards in a few hours with inexpensive equipment. Short development cycles have previously been restricted to the domain of software projects. Hardware designers can now benefit from improved, if still somewhat slow, cycle times. source
FreePCB is a free, open-source PCB editor for Microsoft Windows, released under the GNU General Public License. It was designed to be easy to learn and easy to use, yet capable of professional-quality work. It does not have a built-in autorouter, but it can use the FreeRoute web-based autorouter at www.freerouting.net. Some of its features are:
The EAGLE Layout Editor is an easy to use, yet powerful tool for designing printed circuit boards (PCBs).
The program consists of three main modules
General features
Also ,the EAGLE Light Edition can be used for free.CadSoft offers special conditions for EAGLE users who need more power than provided by the Freeware Edition, but don’t want to spend the full price of the Standard Edition. Since these users are typically hobbyists, this special license is granted on a non-profit base, which means that it must not be used in any commercial context. Or, in plain English: you must not earn any money by using this special non-profit EAGLE license.The non-profit license is a single user license that enables all the features of the EAGLE Standard Edition (limited to four signal layers and 160x100mm routing area) with all three modules (Layout+Schematic+Autorouter). source
