CADENCE SIP RF ARCHITECT While system-in-package (SiP) design makes it possible to combine RF and analog content on the same substrate, it presents a number of challenges. These include designing and integrating RF/analog chips with substrate-level buried RF passive devices as well as enabling top-level pre- and post-layout circuit simulation of the entire SiP design. Cadence SiP RF Architect provides the proven path between analog design and simulation and SiP RF layout. It enables designers to create a single, system-level, circuit simulation-ready schematic for RF/analog die, SiP substrate, and packaged and embedded discretes.
