Popis: With the increasing integration density in modern designs new scenarios such as coupling and noise propagation need to be considered in top-level chip verification. Current state-of-the-art AMS simulation tools are not powerful enough for this task. Therefore an event-driven modeling approach using SystemVerilog and C++is used to efficiently describe noise propagation through power supply in RF systems. Signals are represented in the Fourier domain using time-varying phasors to describe RF signals as equivalent baseband and noise as a spectrum with multiple frequency components. A Δ∑-ADC for wireless applications is used as an example to show the model building process and possible system-level investigations.
