Discrete Event System Specification (DEVS) is a formal modeling and simulation (M&S) framework that supports hierarchical, modular models. DEVS-based M&S environments have been used successfully to understand, analyze, and develop a variety of systems. Some of the environments and systems modeled with DEVS are difficult to replicate and analyze; on the other hand, some others are populated with small, embedded devices that perform critical operations with dedicated hardware and software. In both cases the design, simulation and test of these models tend to grow in size and complexity. In each of the development stages, different methods of modeling, implementation and testing are used without any relation among them. CD++ is a modeling and simulation toolkit based on the DEVS formalism. This thesis proposes a modeling, simulation and benchmarking environment based on the CD++ toolkit. Two different tools are presented to the user of the CD++ toolkit: a Benchmarking tool for comparison of the modelling and simulation CD++ tool with other simulators including a benchmarking methodology, and an Integrated Development Environment (IDE) for the conception and construction of models of Real-Time embedded systems, as well as the final implementation and deployment on an
