EAGLE by Cadsoft is a flexible and expandable EDA
schematic capture, PCB layout, autorouter and CAM program widely used since 1988.
, for designing circuit diagram
s. Parts can be placed on many sheets and connected together through ports.
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

PCB layout
The PCBPrinted circuit board
A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. It is also referred to as printed wiring board or etched wiring...

EAGLE saves Gerber
Gerber File
The Gerber format is a file format used by printed circuit board industry software to describe the images of a printed circuit board . The Gerber format is the de-facto industry standard for printed circuit board image transfer.There are two versions. RS-274X is the most commonly used today...
