We describe a complete FPGA-based emulation software system using Virtual Wires technology and present the results of emulating an 18K-gate ASIC implementation of a Sparc microprocessor. Virtual wires overcomes the pincount limitation that formerly restricted the efficiency of FPGAbased logic emulators. The MIT Virtual Wires softwire compiler accepts a netlist description of the system to be em...

Many model based scientific and engineering methodologies, such as system identification, sensitivity analysis, optimization and control, require a large number of model evaluations. In particular, model based real-time control of urban water infrastructures and online flood alarm systems require fast prediction of the network response at different actuation and/or parameter values. General pur...

The concept of simulating one computer architecture on a system with a completely different architecture has existed for nearly as long as computers themselves. This technique, which has come to be known as emulation, is quickly changing the landscape of the world of computing. Technologies such as the Java programming language have brought emulation into the main stream. If this trend is to co...

The advantage of collaborative containment over independent block or address blacklisting on worm defense has been advocated in previous worm studies. In this work, we will evaluate two collaborative worm containment proposals and present some of the results of our DETER emulation experiments. In the first one, proactive worm containment (PWC), security agents block all suspicious hosts on the ...

SRAM-Filed Programmable Gate Arrays (FPGA) have become one of the most important carriers of digital electronic system because of its many inborn advantages. However, as manufacture of Integrated Circuit evolves towards Very Deep Sub-Micron technology, FPGA designers must be careful of circuit’s Single Event Upset (SEU) susceptibility when used in hostile environment, such as avionics and space...

Container-based network emulation offers high fidelity and a scalable testing environment to bridge the gap between research ideas and real-world network applications. However, containers take their notions of time from the physical system clock, and thus the time-stamped events from different containers are multiplexed to reflect the scheduling serialization by the Linux operating system. Conj...

Recently more and more attention has been paid to the intrusion detection systems (IDS) which don't rely on signature based detection approach. Such solutions try to increase their defense level by using heuristics detection methods like network-level emulation. This technique allows the intrusion detection systems to stop unknown threats, which normally couldn't be stopped by standard signatur...

As integrated circuits become more and more complex the need for fast verification becomes increasingly important. Hardware acceleration is used for fast functional verification. This is an area where software tools for logic simulation are too slow to be useful for large designs, since the number of gates is too high [1]. Another trend in today's electronic systems is an increasing amount of s...

Wireless Mesh Networks (WMN) have proven to be an important technology for interconnecting computer systems in a flexible way. There exist many application areas that profit from WMN technologies such as surveillance and monitoring systems, the wireless integration of mobile clients into a network infrastructure or simply the spontaneous setup of a network for data exchange between several mobi...
