SoC designs consisting of analog, digital, mixed signal, RF and software blocks are commonplace. SystemC AMS offers the potential for a unified modeling approach for such systems through executable specification. SystemC AMS uses different Models of Computation to gain simulation performance, most notably by abstracting timing information which demands the simulator solvers to be fast, fair and simple. In this paper we present a method to fortify SystemC AMS extensions with commercial analog solvers while maintaining adequate simulation speed for an overall system simulation. These solvers are more exact to describe specific circuit behavior in nonlinear conditions and wide time ranges. An example system is also presented that implements the proposed scheme.
