EAGLE is a scriptable electronic design automation application with schematic capture, printed circuit board layout, auto-router and computer-aided manufacturing features. EAGLE stands for Easily Applicable Graphical Layout Editor and is developed by CadSoft Computer GmbH. Cadsoft Computer GmbH was acquired by Autodesk Inc. in 2016.
EAGLE contains a schematic editor, for designing circuit diagrams. Parts can be placed on many sheets and connected together through ports.
The PCB layout editor allows back annotation to the schematic and auto-routing to automatically connect traces based on the connections defined in the schematic.
EAGLE saves Gerber and PostScript layout files and Excellon and Sieb & Meyer drill files. These standard files are accepted by many PCB fabrication companies.
The schematic editor allows you to create a symbolic easy-to-read representation of your design.
The layout editor brings your design to life.
The board represents the physical reality of your design.
The autorouter is a useful tool for placing copper traces between components.
Export Gerber, BOM and SVG
The online export options allow you to export to a variety of formats to share and manufacture your work.
Pros and Cons:
Pros: Eagle CAD is easy for hobbyist just starting out with printed circuit CAD designs and includes free options for limited versions of the tool.
Cons: This software is not mainstream with corporate businesses that have internal PCB designers. Also, to use this tool for higher technology boards requires more manual calculations and routing compared to the higher-end CAD tools.
