Bringing RFIC Design And Verification Into The Modern Era


For decades, developers of radio frequency (RF) chips and other analog/mixed-signal (AMS) integrated circuits (ICs) have used traditional techniques for design and verification. Most RFIC designers have continued to hand-craft active and passive devices, manually place and route their circuits, and rely on the bring-up lab to validate their pre-silicon SPICE simulations. It is often said that a... » read more

The Value Of RF Harmonic Balance Analyses For Analog Verification


By Pradeep Thiagarajan and Scott Guyton The world we live in is intricately connected by electronic systems that are expected to function flawlessly to satisfy consumer needs. Functionality violations beyond certain tolerance levels are frowned upon and negatively impact the quality level of products. These systems are required to function accurately, in tandem with other interdependent syst... » read more

Radio Frequency Technology Is Found Everywhere In Daily Life


By Greg Curtis and YuLing Lin Innovation is everywhere around us. From high-performance computing, communications, autonomous driving, and the Internet of Things (figure 1), each segment has led to a rapid increase in design innovation. This innovation has been particularly true in communications, as Radio Frequency (RF) technology is found everywhere in daily life. RF technology is critical... » read more

Plan-Based Analog Verification Methodology


The ability to verify all the aspects of an analog design and to keep track of all the different verification tasks is a growing challenge. Manual attempts to do so often lead to mistakes since they rely on constantly updated documents. The Cadence Virtuoso ADE Verifier provides an overarching verification plan that links to all analog tests across multiple designers. The Virtuoso ADE Verifier ... » read more

Culture Clash In Analog


The analog/mixed signal world is being shaken up by a mix of new tools, an influx of younger engineers with new and broader approaches, and an emphasis on changing methodologies to improve time to market. Analog and digital engineers have never quite seen eye-to-eye. Analog teams leverage techniques that have been around, in some cases, for decades, while digital teams rely heavily on the la... » read more
