Trends in RF Computer Aided Design

GHz frequencies, Gb/s data transmission rates and Gsps data sampling rates are typical in today’s high-performance electronics design. Time domain metrics such as eye-diagrams, TDR measurements and SSN are now appearing simultaneously on the same spec sheet with frequency domain metrics such as phase noise margins and insertion loss. Large transistor counts, high non-linearities and increased full-wave behavior of on-chip and on-board interconnects have become commonplace. This talk will describe the revolution in RF design tools that is occurring to meet these challenges. It will describe new approaches to circuit simulation that integrate transient simulation with harmonic balance from the same integrated schematic. It will describe procedures that combine electromagnetic field simulation with electrical circuit simulation for modeling on-chip interconnects and other passive structures. And it will describe the seamless integration of 3D electromagnetics with circuit simulation currently used at IC foundries such as UMC and TSMC.
