ABSTRACT
This chapter presents an overview of the modeling and simulation methods that are needed to design and embed analog and radio frequency blocks in mixed-signal integrated systems. It reviews mixed-signal simulation methods at different hierarchical levels, and describes techniques to generate analog behavioral models, including regression-based methods as well as model-order reduction techniques. The chapter addresses mixed-signal design methodologies and describes techniques and examples for architectural exploration and top-down hierarchical design refinement. It discusses mixed-signal simulation techniques. The chapter describes analog and mixed-signal behavioral simulation and the corresponding hardware description languages. The high-level exploration environment would also help in deciding on other important system-level decisions, such as determining the optimal partitioning between analog and digital implementations in a mixed-signal system, or deciding on the frequency planning of the system, all based on quantitative data rather than ad hoc heuristics or past experiences.
