Design Rule Checking
In electronic design automation, a design rule is a geometric constraint imposed on circuit board, semiconductor device, and integrated circuit (IC) designers to ensure their designs function properly, reliably, and can be produced with acceptable yield. Design rules for production are developed by process engineers based on the capability of their processes to realize design intent. Electronic design automation is used extensively to ensure that designers do not violate design rules; a process called design rule checking (DRC). DRC is a major step during physical verification signoff on the design, which also involves LVS ( layout versus schematic) checks, XOR checks, ERC (electrical rule check), and antenna checks. The importance of design rules and DRC is greatest for ICs, which have micro- or nano-scale geometries; for advanced processes, some fabs also insist upon the use of more restricted rules to improve yield. Design rules Design rules are a series of parameters provi ...

Electronic Design Automation
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), is a category of software tools for designing Electronics, electronic systems such as integrated circuits and printed circuit boards. The tools work together in a Design flow (EDA), design flow that chip designers use to design and analyze entire semiconductor chips. Since a modern semiconductor chip can have billions of components, EDA tools are essential for their design; this article in particular describes EDA specifically with respect to integrated circuits (ICs). History Early days The earliest electronic design automation is attributed to IBM with the documentation of its IBM 700/7000 series, 700 series computers in the 1950s. Prior to the development of EDA, integrated circuits were designed by hand and manually laid out. Some advanced shops used geometric software to generate tapes for a Gerber format, Gerber photoplotter, responsible for generating a monochromatic ex ...

Altium Designer
Altium Designer (AD) is a printed circuit board (PCB) and electronic design automation software package for printed circuit boards. It is developed by American software company Altium Limited. Altium Designer was formerly named under the brand ''Protel''. History Altium Designer was originally launched in 2005 by Altium, then named Protel Systems Pty Ltd. It has roots in 1985, when the company launched the DOS-based PCB design tool named Protel PCB (which later emerged into Autotrax and Easytrax). Originally it was sold only in Australia. Protel PCB was marketed internationally by HST Technology since 1986. The product became available in the United States, Canada, and Mexico beginning in 1986, marketed by San Diego–based ACCEL Technologies, Inc., under the name Tango PCB. In 1987, Protel launched the circuit diagram editor ''Protel Schematic'' for DOS. In 1991, Protel released ''Advanced Schematic'' and ''Advanced PCB'' 1.0 for Windows (1991–1993), followed by Advanced ...

Magic (software)
Magic is an electronic design automation (EDA) layout tool for very-large-scale integration (VLSI) integrated circuit (IC) originally written by John Ousterhout and his graduate students at UC Berkeley as part of VLSI Project. Work began on the project in February 1983. A primitive version was operational by April 1983, when Joan Pendleton, Shing Kong and other graduate student chip designers suffered through many fast revisions devised to meet their needs in designing the SOAR CPU chip, a follow-on to Berkeley RISC. Fearing that Ousterhout was going to propose another name that started with "C" to match his previous projects ''Cm*'', ''Caesar'', and ''Crystal'', Gordon Hamachi proposed the name ''Magic'' because he liked the idea of being able to say that people used magic to design chips. The rest of the development team enthusiastically agreed to this proposal after he devised the backronym Manhattan Artwork Generator for Integrated Circuits. The Magic software develop ...

Electric (software)
The Electric VLSI Design System is an EDA tool written in the early 1980s by Steven M. Rubin. Electric is used to construct logic wire schematics and to perform analysis of integrated circuit layout. It can also handle hardware description languages such as VHDL and Verilog. The system has many analysis and synthesis tools, including design rule checking, simulation, routing, Layout vs. Schematic, logical effort, and more. Electric is written in Java, and was released as part of the GNU project in 1998 under the GNU General Public License. In 2017, Electric development ceased, but support and bug fixes continue. Alternative design style for integrated circuits Unlike other systems that design integrated circuits (ICs) by manipulating polygons on different layers of the wafer, Electric views IC layout as connected circuitry, similar to the way schematic capture systems work. In Electric, designers place nodes (transistors, contacts, etc.) and connect them with arcs (wires). ...
