Distributed/Real Time Simulation: Integrating Legacy and Modern Codes

We present an approach to wrapping legacy simulation codes with CORBA IDLs based on the DEVS (Discrete Event System Specification) formalism that allows their integration into a heterogeneous, distributed, and collaborative modeling and simulation infrastructure. A family of CORBA-based architectures is discussed that offers a unifying framework enabling legacy codes to be revitalized and execute within modern object-oriented modeling and simulation environments. This is third of a series of papers on interfacing discrete and continuous models presented at this conference. The others are “Systems Theory Background for Continuous/Discrete Integration” and “Interfacing Discrete and Continuous Models for Simulation and Control.”
