A New Era in Complex Information
Technology System Design: Bootstrapping Modeling and Simulation with FPGA-based Hardware
Synthesis
Abstract
Information Technology (IT) systems are already pervasive and promise to become even more
encompassing, powerful, capable, and useful in the future. The lack of a systematic and
scientific IT system design methodology has compelled system designers to resort to ad hoc
techniques, as a result of which, many of today's IT systems suffer from lack of accuracy,
security, and reliability, and succumb to frequent failures.
Consider, for example, a series of successive power failures in different regions across
the US, eventually resulting in the loss of the entire power grid. According to the
literature, a scientific principle that can systematically bring the power stations back
on-line without causing them to trip over and set off a cascading, domino effect, is
unknown at the present time. Clearly, to address the growing need for larger and more
complex IT systems in the future, it is imperative to develop a scientific design
methodology that will yield precise, secure, and robust IT systems.
Careful examination reveals that while the design paradigm for most of the current IT
systems are ad hoc, a few have employed analytic modeling, and an even fewer have utilized
centralized simulation techniques. Neither analytic modeling nor centralized simulation
can, in general, accurately capture reality. Recent literature contains references to the
use of behavior modeling and large-scale asynchronous distributed simulation that yields
results close to reality. Despite this significant advance, industry has not rushed out to
embrace the results of asynchronous distributed simulation and utilize them in the design
of new IT systems.
The result is a continuing void -- lack of migration of innovative IT ideas into new and
meaningful products and services. Even the defense and government agencies in the US are
finding it hard to get industry to manufacture new network security products, except at an
exorbitant cost.
This presentation will focus on a revolutionary new approach that bootstraps modeling and
asynchronous distributed simulation with field programmable gate arrays (FPGAs) based fast
hardware/software prototyping, subject to innovative metric design. It employs a new
principle to realize hybrid analog/discrete system design in a single framework. The
approach is capable of delivering precise and reliable IT products, quickly and
economically, and promises to revolutionize complex IT system design just as VLSI had
brought about a revolution in circuit design in the early 1980s.
Sumit Ghosh is the Thomas E. Hattrick
Professor of Information Systems Engineering in the Department of Electrical and Computer
Engineering at Stevens Institute of Technology in Hoboken, New Jersey. He also serves as
the director of the computer engineering program. Prior to Stevens, he had served as the
associate chair for research and graduate programs in the Computer Science and Engineering
Department at Arizona State University, before which he had been on the faculty at Brown
University, Rhode Island, and even before that he had been a member of technical staff
(principal investigator) at Bell Laboratories Research in Holmdel, New Jersey. He received
his B. Tech degree from the Indian Institute of Technology at Kanpur, India, and his M.S.
and Ph.D. degrees from Stanford University, California. Sumit's additional industrial
experience includes Silvar-Lisco in Menlo Park, CA., Fairchild Advanced Research and
Development, and Schlumberger Palo Alto Research Center. His research focuses on
fundamental and challenging yet practical problems that are of potential benefit to
society. Principal areas include next generation nVHDL, next generation secure ATM network
design, next generation IP router architecture, determining network operating point for
operational networks, deep space networking and distributed visualization, and next
generation asynchronous distributed simulation-based netcentric complex system design,
validation, and testing. A more detailed list of current research pursuits may be viewed

Sumit is the author/co-author of three original monographs/books: Hardware Description
Languages: Concepts and Principles (IEEE Press, 2000); Modeling and Asynchronous
Distributed Simulation of Complex Systems (IEEE Press, 2000); and Intelligent
Transportation Systems: New Principles and Architectures (CRC Press, 2000). Sumit has
written 85+ transactions/journal papers and 80+ refereed conference papers. He serves as
associate editors for the Transactions of the Society for Computer Simulation
International, IEEE Transactions on Fuzzy Systems, IEEE Transactions on Systems, Man, and
Cybernetics, and is on the editorial board of the IEEE Press Book Series on
Microelectronic Systems Principles and Practice. Sumit is the founder (1995) of the
Networking and Distributed Algorithms Lab. at ASU. Sumit is a US citizen. Sumit has held
visiting professor positions at Federal University of Rio de Janeiro (Brazil), University
of Marseilles (France),and Kuwait University (Kuwait).

Simulating Autonomous Agents with
Augmented Reality
Abstract
In many applications such as airport operations (for capacity planning), military
simulations (for tactical planning), and medical simulations (for the planning of surgical
operations), it is very useful to conduct simulations within physically realistic contexts
which are represented by real video imaging sequences.
Furthermore, it is important that the simulated entities conduct autonomous actions which
are realistic and which follow plans of action or intelligent behavior in reaction to
current situations. In this paper we describe the work we have conducted to incorporate
intelligent and realistic behavior within an augmented reality setting. We discuss both
the computer vision aspects that we have addressed and solved, and the issues related to
the design of animated intelligent objects within the simulation.
