A framework for the design of mixed-signal systems with polymorphic signals

Embedded systems are very heterogeneous: They include software, analog/RF, digital hardware, and non-electronic components such as sensors or actuators. To handle the high complexity, an efficient and flexible simulation methodology is needed. Therefore we present a framework in SystemC-AMS that enables communication of different models of computation (MoCs) via polymorphic signals. Thereby mixed-level simulation, successive refinement and the evaluation of synthesized components are supported.
