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.
Of these, LTSpice and Micro-cap are free proprietary softwares based on SPICE. Micro-Cap was released as freeware in July 2019, when its parent company Spectrum Software closed down while LTSpice has been free for a long time.
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 uses an integrated environment for all of the stages of the design process: Schematic capture, PCB layout, Gerber file generation/visualization, and library editing. KiCad is a cross-platform program, written in C++ with wxWidgets to run on FreeBSD, Linux, Microsoft Windows and Mac OS X. Many component libraries are available, and users ...
EAGLE saves Gerber and PostScript layout files as well as Excellon and Sieb & Meyer drill files. These are standard file formats accepted by PCB fabrication companies, but given EAGLE's typical user base of small design firms and hobbyists, many PCB fabricators and assembly shops also accept EAGLE board files (with extension .BRD) directly to ...
SolveSpace v3.0 is able to export 2D sketches and surfaces into DXF/DWG (AutoCAD version 2007), PDF, SVG, EPS, and HPGL file formats. Wireframes can be exported as DXF and STEP files. Polygon meshes can be exported as STL and Wavefront OBJ; NURBS as STEP. SolveSpace is able to export models in STEP, STL, and G-code for reuse in third-party CAM ...
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.
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.
