SystemC-WMS: Wave Mixed Signal Simulator for Nonlinear Heterogeneous Systems

The present paper proposes a methodology for extending SystemC to mixed signal heterogeneous systems. To that end, a method for modelling analog modules using wave quantities is proposed, and a new kind of port and channel were defined. This class library is plugged directly on top of the standard SystemC kernel, so as to allow a seamless integration with the pre-existing simulation environment, and is designed to permit total interconnection freedom between analog modules to ease the development of reusable analog libraries. Moreover, this allows for a uniform treatment of heterogeneous domains. To highlight all these aspects a buck-converter with digital control and an induction motor were simulated.
