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.
