Continuous-time systems can be converted to discrete-event descriptions using the Quantised State Systems (QSS) formalism. Hence it is possible to simulate continuous-time systems using a discrete-event simulation tool, such as a simulation engine based on the DEVS formalism. A new Dymola library, ModelicaDEVS, was developed that implements the DEVS formalism. DEVS has been shown to be efficient for the simulation of systems exhibiting frequent switching operations, such as flyback converters. ModelicaDEVS contain a number of basic components that can be used to carry out DEVS simulations of physical systems. Furthermore, it is also possible – with some restrictions – to combine the two simulation types of ModelicaDEVS and Dymola (discrete-event and discrete-time simulation) and create hybrid models that contain ModelicaDEVS as well as standard Dymola components.
