It 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.

History
EEsof was founded in 1983 by an entrepreneur, Charles J. ("Chuck") Abronson, and a former Compact Software employee, Bill Childs.[1][2][3]
EEsof's first products included high-frequency circuit simulators such as Touchstone and Libra. Although the Touchstone simulator itself is obsolete,[4] its eponymous file format lives on.
