17.2 / October 2016 Written in C/C++ (originally ) Proprietary Website OrCAD Systems Corporation was a software company that made OrCAD, a proprietary software tool suite used primarily for (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.

OrCAD was taken over by in 1999 and was integrated with since 2005. The name OrCAD is a portmanteau, reflecting the company and its software's origins: Oregon +. Contents • • • • • • • • • • 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. Durbetaki, who had left 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. 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) for, which shipped first in late 1985. In 1986, OrCAD hired Peter LoCascio to develop sales and co-founder Ken Seymour left the company.

The flagship SDT product was soon followed with a digital simulator, VST (Verification and Simulation Tools) and printed circuit board (PCB) layout tools. Over time, OrCAD's product line broadened to include -based software products to assist electronics designers in developing (FPGAs), including (CPLDs). In 1991, Durbetaki, then CEO and head of R&D, left the company. Windows 8.1.
