Real-time simulation techniques based on the RTO.k object modeling

Real-time simulation is an advanced mode of simulation in which the simulation objects are designed to show the same timing behavior as the simulation targets. A new approach to real-time simulation which is based on the RTO.k object modeling is discussed. The RTO.k object, which is a real-time extension of the well-established object structure, is capable of uniformly and accurately representing both real-time embedded computer systems and application environments. This simulation approach has many attractive features, e.g., expandability, modifiability, adaptability for efficient parallel processing, etc. In spite of its promising nature, the approach is an immature one in many respects and some desirable directions for future work aimed toward maturing the technology are also discussed.
