Connecting SystemC-AMS models with OSCI TLM 2.0 models using temporal decoupling

Recent additions to the system modelling language SystemC, namely SystemC-AMS and OSCI TLM 2.0, provide more efficient ways to model systems within their respective domains. However, most of todaypsilas embedded systems are usually heterogeneous, requiring some way to connect and simulate models from different domains. In this paper we present a first approach on connecting SystemC-AMS models and TLM 2.0 models using temporal decoupling. We show how certain properties of the involved models of computation can be exploited to maintain high simulation performance. Using an example to show the feasibility of our approach, we could also observe a certain tradeoff between simulation performance and accuracy. Further on, we discuss semantical issues and decisions that have to be made, when models are connected. As these decisions are typically application-driven, we propose a converter structure that keeps converters simple but also provides ways to model application-specific behaviour.
