If you are looking for an easy to use, powerful and affordable schematic capture and printed circuit board design package that gets the job done, EAGLE is the number 1 choice!
CadSoft offers user friendly, powerful and affordable solutions for PCB design, including Schematic Capture, Board Layout, and Autorouter.
Take this Guided Tour and discover EAGLE. You will be surprised!
EAGLE provides a schematic editor, for designing circuit diagrams and a tightly integrated PCB layout editor, which automatically starts off with all of the components required by the schematic. Components are manually arranged on the board, with the help of coloured lines showing the eventual connections between pins that are required by the schematic, to aid in finding a placement that will allow the most efficient track layout.
It also provides a good autorouter, which once the components have been placed will attempt to automatically find an optimal track layout to make the electrical connections. It does not always manage to find a way of routing all the signals, although it permits manual routing of critical paths such as power and high frequency lines before letting the autorouter handle the other connections.
EAGLE is very popular with hobbyists because the free demo is able to create usable PCBs. (Free ECADs from some companies are crippled so that they won't save or won't print.) The only limitations of boards made with the EAGLE demo are: 2 copper layers; a maximum size of 80mm x 100mm (½ Eurocard)(~3in x ~4in). The demo version of the schematic editor module can only create single-sheet schematics.
