Hybrid simulation may employ different types of simulators based on which models in different system types are developed. The simulation requires simulation time synchronization and data exchange between such simulators, which is called simulators interoperation. This paper develops such interoperable simulation environments for modeling and simulation of hybrid systems whose components consist of continuous and discrete event systems. The environments, one for centerized and the other for distributed, support interoperation between a discrete event simulator of DEVSim++, and a continuous simulator of MATLAB. The centerized environment , HDEVSim++ is developed by extending the existing DEVSim++, environment. The distributed environment , HDEVSimHLA, is developed using the HLA/RTI library. Verification of both environments is made and performance comparison between the two using a simple example is presented
