SystemC-AMS extension library for modeling conservative nonlinear dynamic systems

SystemC-AMS is an extension of SystemC which provides additional language constructs for modeling analog mixed signal behavior. The currently available version of SystemC-AMS is optimized for signal processing dominated applications and allows modeling of conservative linear (linear electrical networks) and non-conservative (signalflow) behavior with linear dynamic and non-linear static equations. This paper presents first experiments for an extension of SystemC-AMS for modeling conservative elements with nonlinear dynamic algebraic equations. Some considerations on equation setup, solvability, SystemC-AMS integration, and a first proposal for the language constructs will be presented. Results are demonstrated by means of numeric examples, transistor circuits, and a complex electro mechanical system
