Keysight EDA actively engages with component manufacturers to create model libraries that will enable you to access the latest models and technologies. There are numerous vendors providing libraries for Keysight's PathWave Advanced Design System (ADS) RF and Microwave Design Software.

Component vendors use Keysight software, hardware, and expertise to develop models for use in electronic design automation (EDA) simulation tools. By assisting vendors in this process and using a web-based model delivery approach, Keysight EDA customers can augment their existing ADS libraries of over 100,000 parts with the latest available parts from the industry. Additionally, Keysight EDA provides an easy-to-use Library Builder tool to vendors who would like to supply ADS model libraries for their components.

The ADS models provided by the vendors listed in the table below generally fall in one or more of these three categories: ADS design kits (these may include symbols and/or layout footprints), models in the Keysight EDA’s industry-standard Touchstone .snp (S-Parameter) format, and SPICE models compatible with ADS. Additionally, Modelithics, Inc. provides high-accuracy RF and Microwave active and passive simulation models  for components from several vendors.

Note: If you are a vendor and would like to be added to the following table by providing your model libraries for ADS, or would like to extend your current model libraries to include symbols and/or layout footprints, please send us an e-mail at
