The dissertation introduces RecDEVS, a model of computation for reconfigurable hardware systems. Existing computational models for conventional hardware structures are not suited very well to model the dynamic behavior of reconfigurable systems. This work first systematically investigates the requirements that are necessary to properly model reconfigurable systems. Then, the Discrete Event System Specification (DEVS) formalism is extended into RecDEVS, a formalism capable of modeling reconfigurable systems. It is then demonstrated how RecDEVS can be utilized to do a a model based design flow that eases system verification.
