We present a new Simulink (Simulink) to Modelica (Mod-elica) translation chain embedded into Nsp. Translated models can be edited (original Simulink diagrams are preserved through translation) and simulated. This translation chain makes use of the Simport tool, originally designed to translate Simulink models to Scicos models, and also relies on Modelicac, i.e. Scicos' Modelica companion compiler. Using some examples, we demonstrate the effectiveness of the translation process and detail some technical aspects of it. This new Nsp feature extends Nsp's simulation capabilities and makes it a reference platform for users looking for means to simulate Simulink models within a Modelica framework. Resulting Modelica code can even be exported to other Modelica compatible tools.
