This study describes the current implementation of an interface that automatically translates a discontinuous model described using the Modelica language into the Discrete Event System Specification (DEVS) formalism. More specifically; the interface enables the automatic simulation of a Modelica model with discontinuities in the PowerDEVS environment; where the Quantized State Systems (QSS) integration methods are implemented. Providing DEVS-based simulation algorithms to Modelica users should extend significantly the tools that are currently available in order to efficiently simulate several classes of largescale real-world problems; e.g. systems with heavy discontinuities. In this work both the theoretical design and the implementation of the interface are discussed. Furthermore; simulation results are provided that demonstrate the correctness of the proposed implementation as well as the superior performance of QSS methods when simulating discontinuous systems.
