P-CAD
P-CAD was the brand name of Personal CAD Systems, Inc., a California based manufacturer of electronic design automation software. It manufactured a CAD software available for personal computers. The company was divested into ACCEL Technologies which was purchased by Altium in 2000. The last release of the software was in 2006 before it was retired in favor of the Altium Designer product. History Personal CAD Systems was founded in 1982 by Richard Nedbal and Roy Prasad. Both were former executives of American Microsystems, Inc. (AMI), a custom semiconductor company based in Santa Clara, California. Also, part of the founding team were Gregory Houston, VP Marketing, a former Calma executive, and Chi-Song Horng, Director of software engineering (later promoted as a Vice President), a former AMI software engineering manager. P-CAD was a play on personal computers, which were just becoming popular, following the launch of the IBM PC. The vision of the company was to disrupt the exis ...

P-CAD Interface For SPECCTRA
Specctra is a commercial PCB auto-router originally developed by John F. Cooper and David Chyan of Cooper & Chyan Technology, Inc. (CCT) in 1989. The company and product were taken over by Cadence Design Systems in May 1997. Since its integration into Cadence's Allegro PCB Editor, the name of the router is Allegro PCB Router. The latest version is 17.4 - 22.1 (October 20 2022). Specctra routes boards by presenting graphical data using a "shape-based" technology which represents graphical objects not as a set of points-coordinates, but more compact. This increases the efficiency of routing printed circuit boards with a high density of components, provides automatic routing of the same chain of tracks of different widths and more. Specctra uses adaptive algorithms implemented in multiple trace runs. The routing is carried out in three stages: # preview routing # autoroute # additional processing of autoroute results On the first pass, the connection of all conductors is perfo ...

Cadam
CADAM (computer-augmented design and manufacturing) is CAD-related software that was developed by Lockheed. CADAM was originally written for IBM mainframes and later ported to UNIX workstations, including the IBM RT PC. A variant of CADAM called Micro CADAM was also developed for PCs under DOS. History * 1977: IBM agreed to sell CADAM to aerospace companies. * 1981: CADAM Release 18.3 was released. It provided support for IBM mainframes running VM/CMS. * 1983: CADAM Inc is formed as a subsidiary of Lockheed Corp. * 1985: CADAM Inc successfully sued Adage over the CADAM look-and-feel. It was one of the first look-and-feel court cases. * 1987: CADAM Inc and SDRC won a massive GM C4 benchmark. CADAM agreed to port Professional CADAM to Sun, Apollo and HP. * 1989: CADAM Inc was sold to IBM. CADAM Inc, an IBM Company, was formed. * 1990: Microcadam was formed.

Schematic Capture
Schematic capture or schematic entry is a step in the design cycle of electronic design automation (EDA) at which the electronic diagram, or electronic schematic of the designed electronic circuit is created by a designer. This is done interactively with the help of a schematic capture tool also known as schematic editor. The circuit design is the first step of actual design of an electronic circuit. Typically sketches are drawn on paper, and then entered into a computer using a schematic editor. Therefore schematic entry is said to be a front-end operation of several others in the design flow. Despite the complexity of modern components – huge ball grid arrays and tiny passive components – schematic capture is easier today than it has been for many years. CAD software is easier to use and is available in full-featured expensive packages, very capable mid-range packages that sometimes have free versions and completely free versions that are either open source or directl ...

San Diego
San Diego ( , ; ) is a city on the Pacific Ocean coast of Southern California located immediately adjacent to the Mexico–United States border. With a 2020 population of 1,386,932, it is the eighth most populous city in the United States and the seat of San Diego County, the fifth most populous county in the United States, with 3,338,330 estimated residents as of 2019.

Printed Circuit Board
A printed circuit board (PCB; also printed wiring board or PWB) is a medium used in electrical and electronic engineering to connect electronic components to one another in a controlled manner. 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 (similar to wires on a flat surface) 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. Printed circuit boards are used in nearly all electronic products. Alternatives to PCBs include wire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logic Simulation
Logic simulation is the use of simulation software to predict the behavior of digital circuits and hardware description languages. Simulation can be performed at varying degrees of physical abstraction, such as at the transistor level, gate level, register-transfer level (RTL), electronic system-level (ESL), or behavioral level. Use in verification Logic simulation may be used as part of the verification process in designing hardware. Simulations have the advantage of providing a familiar look and feel to the user in that it is constructed from the same language and symbols used in design. By allowing the user to interact directly with the design, simulation is a natural way for the designer to get feedback on their design. Length of simulation The level of effort required to debug and then verify the design is proportional to the maturity of the design. That is, early in the design's life, bugs and incorrect behavior are usually found quickly. As the design matures, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Design Automation
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), is a category of software tools for designing electronic systems such as integrated circuits and printed circuit boards. The tools work together in a 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 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 photoplotter, responsible for generating a monochromatic exposure image, but even those copied digital recordings of mechanically drawn components. The process was fundamentally graphic, with the translation from electronics to graphics done manu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
