Heterogeneous architecture and testbed for simulation of large-scale real-time systems

This paper presents the development of distributed simulation architecture and testbed by combining three different types of tools based on three different approaches to real-time simulation: queuing theory (with SES/workbench as supporting tool); finite state machines (with high-level software design tools, such as Rational Rose Realtime or ObjecTime Developer); and continuous simulation based on solving differential equations (injecting real-time data from a real-time simulator running on a VMEbus platform under VxWorks real-time kernel). Such a combination is very advantageous because it provides the capability of making real-time decisions within the design and simulation tools which can help significantly improve the quality of simulations.
