EEsof (/ˈiːsɒf/ EESOF; electronic engineering software), today known as Keysight EEsof EDA, is a provider of electronic design automation (EDA) software that helps engineers design products such as cellular phones, wireless networks, radar, satellite communications systems, and high-speed digital wireline infrastructure. Applications include electronic system level (ESL), high-speed digital, RF-Mixed signal, device modeling, RF and Microwave design for commercial wireless, aerospace, and defense markets.
EEsof was founded in 1983 by an entrepreneur, Charles J. ("Chuck") Abronson, and a former Compact Software employee, Bill Childs.
EEsof's first products included high frequency circuit simulators such as Touchstone and Libra. Although the Touchstone simulator itself is obsolete, its eponymous file format lives on. EEsof was acquired by Hewlett-Packard in 1993 and later spun out first as part of Agilent Technologies in 1999 and then as part of Keysight Technologies thus becoming Keysight EEsof EDA.
After the merger of HP and EEsof, the EEsof products were combined with the HP simulator, Microwave Design System (MDS). HP's own entry, MDS, had been introduced in 1985. It was developed in-house and comprised a linear circuit simulator with integrated schematic capture and graphical layout with back-annotation, a first for RF EDA software. MDS was offered on UNIX workstations from HP, Sun, and Apollo as well on the PC. Prior to the introduction of MDS, HP had a marketing relationship with EEsof and sold Touchstone software on HP platforms such as the Series 200 (but not on the PC). The marketing relationship ended after the introduction of HP's MDS product.
