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 (German: Einfach Anzuwendender Grafischer Layout-Editor) and is developed by CadSoft Computer GmbH. CadSoft Computer GmbH was acquired by Autodesk Inc. in 2016.
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.
A large group of textual and video tutorials exists for beginners to design their own PCBs.
SparkFun Electronics is a company that has grown due to the hobbyist market exemplified by Make magazine and others. Many of these companies offer EAGLE part libraries which define schematic shapes, pinouts, and part sizes to allow for correct layout in the PCB layout editor. Other popular libraries include Adafruit, SnapEDA, and Dangerous Prototypes, element14 (a subsidiary of Farnell, former owners of CadSoft) also have some libraries available from their site.
The German CadSoft Computer GmbH was founded by Rudolf Hofer and Klaus-Peter Schmidinger in 1988 to develop EAGLE, a 16-bit PCB design application for DOS. Version 2.6 changed the definition of layers, but designs created under older versions (up to 2.05) could be converted into the new format using the provided UPDATE26.EXE utility. Support for OS/2 and Windows was added later on.
Starting with version 4.0 in 2000, EAGLE was converted to 32-bit. EAGLE version 4.0 officially dropped support for DOS and OS/2, but was among the first professional electronic CAD tools available for Linux. A 32-bit DPMI version of EAGLE 4.0 running under DOS was still available on special request in order to help support existing customers, but it was not released commercially. Much later in 2015 a special version of EAGLE 4.09r2 was made available by CadSoft to ease installation under Windows 7.
Version 5.91.0 introduced the new XML file format in 2011, but continued to read the older binary format. It could not, however, write files in the former format, thereby not allowing collaboration with EAGLE 5.12.0 and earlier. EAGLE 6.0.0 no longer supported Mac OS X on the Power PC platform (only on Intel Macs), and the minimum requirements were changed to Mac OS X 10.6, Linux 2.6 and Windows XP.
Version 7.3.0 introduced native 64-bit versions for all three platforms in 2015. Version 7.6.0 dropped support for the 32-bit Mac OS X version in 2016.
On 27 June 2016, Autodesk announced the acquisition of CadSoft Computer GmbH from Premier Farnell, with Premier Farnell continuing to distribute Cadsoft products for Autodesk. Autodesk changed the license to a subscription-only model starting with version 8.0.0 in 2017. Only 64-bit versions remain available any more.
As of EAGLE version 8.0, there are Premium, Standard, free, and student & educator editions, with the Standard and Premium versions sold on a monthly or annual subscription basis, requiring online reactivation at least every 14 days.
|Version||Schematic sheets||Layers||PCB size||Use||Cost/month||Cost/year|
|free||2||2||80 cm²||For individual, non-commercial use only||free||free|
|student and educator||999||16||4 m²||For student and educator use only||free||free|
In spring 1991 EAGLE's dongle protection scheme had been cracked causing a decline of 30% in sales, while sales for a reduced demo version with printed manual had seen a significant increase. As a consequence in 1992 CadSoft sent thousands of floppy disks containing a new demo of EAGLE to potential users, in particular those who had ordered the former demo but had not subsequently bought the full product. The new demo, however, also contained spy code scanning the user's hard disk for illegal copies of EAGLE. If the program found traces of such, it would show a message indicating that the user was entitled to order a free printed manual using the displayed special order code, which, however, was actually a number encoding the evidence found on the user's machine. Users sending in the filled out form would receive reply from CadSoft's attorneys. The act of spying, however, was illegal as well by German law.
In 2014, EAGLE 7.0 introduced a new FLEXlm-based Flexera licensing model, which wasn't well received by the user community, so that CadSoft returned to the former model of independent perpetual licenses with EAGLE 7.1.
Despite announcements to the contrary in 2016, Autodesk switched to a subscription-only licensing model with EAGLE 8.0 in January 2017. Without an online connection to a licensing server to verify the licensing status every two weeks, the software would fall back to the functionality of the freeware version. This caused an uproar in the user community, in particular among those who work in secure or remote environments without direct internet access and users for whom it is mandantory to be able to gain full access to their designs even after extended periods of time (several years or decades) without depending on third-parties such as Autodesk to allow reactivation (who may no longer be around or support the product by then). Many users have indicated they would refuse to upgrade under a subscription model and rather migrate to other electronic design applications such as KiCad.
