The Gerber format is an open, ASCII, vector format for printed circuit board (PCB) designs. [1] It is the de facto standard used by PCB industry software to describe the printed circuit board images: copper layers, solder mask, legend, drill data, etc. [2] [3] [4] The standard file extension is .GBR or .gbr [1] though other extensions like .GB, .geb or .gerber are also used.
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.
KiCad (/ ˈ k iː ˌ k æ d / KEE-kad [7]) is a free software suite for electronic design automation (EDA). It facilitates the design and simulation of electronic hardware for PCB manufacturing. It features an integrated environment for schematic capture, PCB layout, manufacturing file viewing, ngspice-provided SPICE simulation, and
ODB++ is a proprietary CAD-to-CAM data exchange format [1] used in the design and manufacture of electronic devices. Its purpose is to exchange printed circuit board design information between design and manufacturing and between design tools from different EDA/ECAD vendors. [2]
Originally, the project planned to also write a PCB layout program. However, an existing open-source layout program, "PCB", was soon discovered by the project. Thereafter, the ability to target netlists to PCB was quickly built into the gEDA Project's netlister, and plans to write a new layout program from scratch were scrapped.
For each, copy the text in the gray box from this article, paste into an ASCII text editor, saving as a text file. Both files must have the same "base name" and sit in the same directory. To see it, opening the "asc" file with LTspice then click the "Run" button inside LTspice software. LTspice_RC.asc; LTspice_RC.plt
DipTrace is a proprietary software suite for electronic design automation (EDA) used for electronic schematic capture and printed circuit board layouts. DipTrace has four applications: schematic editor, PCB editor with built-in shape-based autorouter and 3D preview, component editor (schematic symbol), and pattern editor (PCB footprint).
The native file format for Autotrax is PCB File 4. Protel also produced a less expensive, cut-down package called Easytrax. This was later made available free, while Autrotrax still required a license; now both are free. Easytrax is identified by "PCB File 5" in its file headers and differs primarily in not allocating hole sizes to pads.
