Advanced Design System

Advanced Design System (ADS) is an electronic design automation software system produced by PathWave Design, a division of Keysight Technologies. It provides an integrated design environment to designers of RF electronic products such as mobile phones, pagers, wireless networks, satellite communications, radar systems, and high-speed data links.

Keysight ADS supports every step of the design process — schematic capture, layout, design rule checking, frequency-domain and time-domain circuit simulation, and electromagnetic field simulation — allowing the engineer to fully characterize and optimize an RF design without changing tools.

Keysight has donated copies of the ADS software to the electrical engineering departments at many universities.
