SC-DEVS: An efficient SystemC extension for the DEVS model of computation

This paper describes a systematic approach to integrate the Discrete Event Specified System (DEVS) methodology into SystemC. It thus combines Model of Computation (MoC) specific properties and the features of an advanced SystemC environment. The execution of abstract system level DEVS models is comparable to pure SystemC models and is significantly faster compared to other DEVS environments. Thus, system level models based on abstract MoCs may easily be executed in a SystemC environment. The proposed integration is realized as a non-introspective extension to the SystemC 2.2 kernel. The DEVS models are implemented on an additional software layer above the SystemC simulation kernel. Our approach may be used simultaneously with other layered extensions, e.g., SystemC-AMS or TLM.
