EAGLE Modules and Editions
3.1 EAGLEModules
A number of EAGLE editions are offered. You can add an Autorouter

The basic EAGLE software package comes with the Layout Editor,
which allows you to design printed circuit boards (pcbs), plus the Libra

tor you can already design packages (footprints), symbols and devices
(for a schematic). The CAM Processor is the program which generates
the output data for the production of the pcb (e.g. Gerber or drill files).

SchematicModule
If you have the schematic module you begin by drawing a circuit dia

gram. You can generate the associated circuit board at any time with a
mouse-click. EAGLE then changes to the Layout Editor, where the
packages are placed next to an empty board - connected via airwires
(rubber bands). From here you can go on designing with the Layout
Editor as usual. Schematic and layout are automatically kept consistent
by EAGLE (Forward&Back Annotation). Schematic diagrams can con
