A printed circuit board (PCB), also called printed wiring board (PWB), is a medium used to connect or "wire" components to one another in a circuit. It takes the form of a laminated sandwich structure of conductive and insulating layers: each of the conductive layers is designed with an artwork pattern of traces, planes and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Electrical components may be fixed to conductive pads on the outer layers in the shape designed to accept the component's terminals, generally by means of soldering, to both electrically connect and mechanically fasten them to it. Another manufacturing process adds vias: plated-through holes that allow interconnections between layers.
In integrated circuit design, integrated circuit (IC) layout, also known IC mask layout or mask design, is the representation of an integrated circuit in terms of planar geometric shapes which correspond to the patterns of metal, oxide, or semiconductor layers that make up the components of the integrated circuit. Originally the overall process was called tapeout, as historically early ICs used graphical black crepe tape on mylar media for photo imaging.
EAGLE is a scriptable electronic design automation (EDA) application with schematic capture, printed circuit board (PCB) layout, auto-router and computer-aided manufacturing (CAM) features. EAGLE stands for Easily Applicable Graphical Layout Editor and is developed by CadSoft Computer GmbH. The company was acquired by Autodesk Inc. in 2016 who announced to support the product up to 2026 only.
CADSTAR is a Windows-based electronic design automation (EDA) software tool for designing and creating schematic diagrams and printed circuit boards (PCBs). It provides engineers with a tool for designing simple or complex, multilayer PCBs. CADSTAR spans schematic capture, variant management, placement, automatic and high-speed routing, signal integrity, power integrity, EMC analysis, design rule checks and production of manufacturing data.
TARGET 3001! is a CAD computer program for EDA and PCB design, developed by Ing.-Büro Friedrich in Germany. It supports the design of electronic schematics, PCBs, and device front panels. It runs under Windows and is available in English, German and French.
OrCAD Systems Corporation was a software company that made OrCAD, a proprietary software tool suite used primarily for electronic design automation (EDA). The software is used mainly by electronic design engineers and electronic technicians to create electronic schematics, and perform mixed-signal simulation and electronic prints for manufacturing printed circuit boards (PCBs). OrCAD was taken over by Cadence Design Systems in 1999 and was integrated with Cadence Allegro in 2005.
XCircuit is a schematic capture program for drawing publication-quality VLSI electrical circuit schematic diagrams and related figures. It's part of the Open Circuit Design tools. It's primarily intended for ULSI/VLSI IC design and not for PCB design, the latter though is still possible. XCircuit regards circuits as inherently hierarchical and can save circuits both in PostScript (.ps) and Ngspice (.cir) netlists file formats for further processing. The program compiles PostScript files from special template-labels specified by user.
The Layout Versus Schematic (LVS) is the class of electronic design automation (EDA) verification software that determines whether a particular integrated circuit layout corresponds to the original schematic or circuit diagram of the design.
KiCad is a free software suite for electronic design automation (EDA). It facilitates the design and simulation of electronic hardware. It features an integrated environment for schematic capture, PCB layout, manufacturing file viewing, ngspice-provided SPICE simulation, and engineering calculation. Tools exist within the package to create bill of materials, artwork, Gerber files, and 3D models of the PCB and its components.
An Integrated circuit layout editor or IC layout editor is an electronic design automation software tool that allows a user to digitize the shapes and patterns that form an integrated circuit. Typically the view will include the components, metal routing tracks, vias and electrical pins. Software of this type is similar to computer aided drafting software, but is specialized for the task of integrated circuit layout. The typical flow for the layout of analog circuits might be :
TopoR is an EDA program developed and maintained by the Russian company Eremex. It is dedicated to laying out a printed circuit board (PCB). The current version is 6.3.17875 as of 2017-09-20.
In electronic design automation, parasitic extraction is the calculation of the parasitic effects in both the designed devices and the required wiring interconnects of an electronic circuit: parasitic capacitances, parasitic resistances and parasitic inductances, commonly called parasitic devices, parasitic components, or simply parasitics.
Altium Designer (AD) is a PCB and electronic design automation software package for printed circuit boards. It is developed by Australian software company Altium Limited.
PCB is a free and open-source software suite for electronic design automation (EDA) - for printed circuit boards (PCB) layout. It uses GTK+ for its GUI widgets.
DesignSpark PCB is a free electronic design automation software package for printed circuit boards. Although there is no charge for the software, the user must register with DesignSpark.com to unlock the program and it displays advertisements which must be acknowledged before the user can begin working.
Pulsonix is an electronic design automation (EDA) software suite for schematic capture and PCB design. It is produced by WestDev, which is headquartered in Gloucestershire, England, with additional sales and distribution offices overseas. It was first released in 2001, and runs on Windows.
Upverter is an electronic circuit design system delivered in a web browser, which enables hardware engineers to design, share, and review schematics and printed circuit boards. It additionally features the ability to generate a bill of materials, Gerber files, and a 3D rendering. Upverter provides web-based tools for editing schematic diagrams and for laying out printed-circuit boards. It does not require payment for open-source projects.
CircuitMaker is electronic design automation software for printed circuit board designs targeted at the hobby, hacker, and maker community. CircuitMaker is available as freeware, and the hardware designed with it may be used for commercial and non-commercial purposes without limitations. It is currently available publicly as version 2.0 by Altium Limited, with the first non-beta release on January 17, 2016.
