Various DEVS (Discrete Event Systems Specification) implementations exist but differ in the approaches considered for use. These approaches include how events are processed, the simulation architecture in use, the existing procedures (set of rules/algorithm), the organizational architecture (of the simulator) and so on. This work attempts to formalize a generic approach to Parallel and Distributed Simulation (PADS) with DEVS as well as embody these approaches by providing formal definitions that can be standardized for use during DEVS implementation. Therefore, we propose a DEVS Simulation Graph which gives basic information about the necessary elements that are useful for the analysis and construction of a DEVS simulator. The major aim is to help identify these elements before implementation and ease the development of a DEVS simulator.
