Historically, Keysight offered a restricted "ADS Lite" version (discontinued after 2015). For 2020, they shifted to the time-limited trial model. However, some universities have site licenses that allow students to download a "nodelocked" version of ADS 2020 from their internal portals. Keysight Advanced Design System -ADS- 2020 Free Download
