This paper describes an open-source simulator for cyber-physical systems called CyPhySim that is based on Ptolemy II. This simulator supports classical (Runge-Kutta) and quantized-state simulation of ordinary differential equations, modal models (hybrid systems), discrete-event models, the Functional Mockup Interface (FMI) for model-exchange and co-simulation, discrete-time (periodic) systems, and algebraic loop solvers. CyPhySim provides a graphical editor, an xml file syntax for models, and an open API for programmatic construction of models. It includes an innovation called "smooth tokens," which allow for a blend of numerical and symbolic computation, and for certain kinds of system models, dramatically reducing the computation required for simulation.
