Electric is used to draw schematics and to do integrated circuit layout. It can also handle hardware description languages such as VHDL and Verilog. Electric has been open-source for many years, and is currently available through the Free Software Foundation (GNU). Advantages: No install — a single Java .jar contains the program and all help ...
The following table is split into two groups based on whether it has a graphical visual interface or not. The latter requires a separate program to provide that feature, such as Qucs-S, [ 1 ] Oregano , [ 2 ] or a schematic design application that supports external simulators, such as KiCad or gEDA .
KiCad schematic editor for schematic capture KiCad PCB editor for board layout and design KiCad 3D viewer showing both VRML and IDF features on a demo board KiCad 3D viewer. KiCad uses an integrated environment for all of the stages of the design process: Schematic capture, PCB layout, Gerber file generation/visualization, and library editing.
EasyEDA is an integrated browser-based tool for schematic capture, SPICE circuit simulation (based on Ngspice) and PCB layout. [3] [4]Import from Altium Designer, CircuitMaker, Eagle, Kicad and LTspice file formats as well as generic SPICE netlists is supported.
This permissive open source license allows its integration as a simulation engine into several — proprietary or free/libre — EDA tools such as KiCad, [10] [11] EAGLE (program), [12] CoolSPICE, Altium and others. Ngspice has a command line input interface and offers plotting capability.
Code-based EDA tool that allows hardware engineers to design electronic circuits and PCBs using a programming-like environment. It integrates hardware design specifications directly into code, enabling intelligent design capture, version control, and continuous integration practices. [15] FreePCB: Windows: GPL: Yes-Gerber: No
Altium Designer supports import & export of various PCB and CAD data exchange file formats. [ 11 ] [ 12 ] The tool's native file formats are the binary file formats *.SchDoc and *.PcbDoc . It can also import and export AutoCAD *.dwg / *.dxf and ISO 10303-21 STEP file formats.
LTspice schematics are stored as an ASCII text file with a filename extension of "asc". [30] The following example shows the contents from a small LTspice schematic file for a simple RC circuit with four schematic symbols: V1 is 10 volt DC voltage source, R1 is 1K ohm resistor, C1 is 1 uF capacitor, ground.
