OrCAD
OrCAD is 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 electronic prints for manufacturing printed circuit boards.
The name OrCAD is a portmanteau, reflecting the company and its software's origins: Oregon + CAD.
==Company==
Founded in 1985 by John Durbetaki, Ken and Keith Seymour as “OrCAD Systems Corporation” in Hillsboro, Oregon, the company became a supplier of desktop electronic design automation (EDA) software. In 1984 Durbetaki began designing an expansion chassis for the IBM PC. Durbetaki, who had left Intel Corp. after five years as an engineer and project manager, decided, along with brothers Keith and Ken Seymour, to start his own company to develop add-on instrumentation for the PC."〔Oregon Business | 1 May 1989 | Paul Gerhards, ("Designing software for "real" engineers: OrCAD Systems Corp." ), accessed 2012-04-01〕 Durbetaki began creating his own schematic capture tool for his use in the PC expansion chassis project; but eventually shelved the hardware project entirely in favor of developing low-cost, PC-based CAD software. The company's first product was SDT (Schematic Design Tools), which shipped first in late 1985.
