Book excerpt: In recent years mixed-signal system-on-chip have gained wide usage. The time to market of these devices are affected by the constrains in prototyping. VHDL-AMS provides the capability of behavioral modeling of mixed-signal designs, which is not available in the conventional SPICE modeling. Using VHDL-AMS, a top-down design approach can be utilized for the mixed-signal systems. This method has been claimed to reduce the time-to-market, when compared to the conventional bottom-up approach used for analog and mixed-signal designs. The main reason for this is the reduced simulation time of top level models (i.e. behavioral models). In this thesis work, we study a modeling approach for a generic successive approximation analog-to-digital converter and its components using VHDL-AMS at varying levels of abstraction. Methods for introducing system features and non-idealities at various abstractions are also discussed.
