LayoutEditor is an IC/MEMS layout editor. It features all angle elements, a font generator, macros, Boolean operations, drc, netlist-driven layout, LVS, and cross-platform compatibility. Supported formats include Calma GDSII, OASIS (Open Artwork System Interchange Standard), DXF, CIF (Caltech Intermediate Form), Gerber, DEF/LEF, and many others.
LinkCAD is an all-in-one converter for AutoCAD DXF, Gerber RS274X, Calma GDS-II, CIF, PostScript, IE3D, TLC, and more. LinkCAD allows you to convert your mask or PCB layout between all the supported formats. Typical users are layout designers in the electronics industry, and mask designers for micro-technology applications.
Liquid PCB is a computer aided design application for designing printed circuit boards. Unlike other PCB CAD applications, you are not restricted to straight tracks and 45º angles. Instead, you can freely draw tracks any way you like, and the tracks themselves will move and bend as required to maintain your design rules. Vias and components are also free to move and rotate. The user interface exposes all functions through the multi-directional expanding mouse menu and the keyboard instead of through icons and menus.
Pcb is a handy tool for the X Window System to design printed circuit boards. All coordinate units are 1/1000 inch. A layout consists of lines, arcs, polygons, elements (lines, pins and arcs), vias, and text information seperated into several layers. Each of them is identified by a unique name and color (if supported by your display). SMD circuits are also supported. Eight layers are supported, in addition to a silkscreen layer. Visibility of pins and SMD pads and vias is controllable. All files are 7-bit ASCII, and can be preprocessed with any Unix command that writes its results to stdout (GNU m4 is required). Zooming, unlimited undo, and unlimited redo are supported. Pcb is intended to be a simple tool without memory and time consuming features like autorouter and autoplacement. Layout related settings are saved together with the data.
