schematics A schematic, or schematic diagram, is a designed representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the ...

simulation A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the s ...

simulation of mixed analogue and digital circuits and the creation and editing of printed circuit board layouts and, optionally, the manufacture of printed circuit boards. Subscription-free membership is offered for public plus a limited number of private projects. The number of private projects can be increased by contributing high quality public projects, schematic symbols, and PCB footprints and/or by paying a monthly subscription. Registered users can download Gerber files from the tool free of charge; but for a fee, EasyEDA offers a PCB fabrication service. This service is also able to accept Gerber file inputs from third party tools.

History

In June 2010, Dillon He and Eric Cui started a survey of EDA tools for a hardware project of their own. The search for an EDA tool capable of schematic capture,

circuit simulation Electronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit. Simulation software allows for modeling of circuit operation and is an invaluable analysis tool. Due to its highly accurat ...

and printed circuit board layout saw limited success, and He concluded that designing their own EDA tool would be beneficial. Their key goals were that the tools be platform independent, free, easy to learn and to use. The first version of the toolsuite appeared online in August 2013 and since officially launching in March 2014 the tool has developed rapidly with several major revisions and enhancements EasyEDA first received external investment in January and attracted more in November 2015.

schematics and symbols provides a useful way to port schematics to PCB layout without having to redraw them from scratch. Once Gerber files of a completed PCB design have been downloaded and checked - using a third party Gerber viewer - the user is free to choose a PCB manufacturer or, for a fee, they can submit the Gerbers directly to EasyEDA for manufacture. Alternatively, printable PCB layer image output is also supported in PDF, PNG and SVG formats for home PCB etching. The tool also includes sharing and collaboration features and a comprehensive parts and an expanding SPICE model library.
