Semiconductor fabrication factories are large enterprises with many toolsets, each having multiple production machines. The process flow is highly reentrant, therefore modeling is best done by discrete-event simulation. To describe such a fab, the author has developed a new discrete event simulator called FabSim. It is written in C++. As the simulation engine it uses SystemC, a C++ class librar...

We describe the design, development and testing of a prototype simulator to study problems associated with robust and efficient solution of dynamic process problems, particularly for systems with models containing moderately to very stiff ordinary differential equations and associated algebraic equations. A new predictor-corrector integration strategy and modular dynamic simulator architecture ...

A geothermal power plant multiple simulator for operators training is presented. The simulator is designed to be installed in a wireless local area network and has a capacity to train one to six operators simultaneously, each one with an independent simulation session. The sessions must be supervised only by one instructor. The main parts of this multiple simulator are: instructor and operator’...

We present a simulation framework to integrate several aspects of the combustion and burning process in a unified and modular manner. A simple three gas flame model is used to simulate a combustion process, while air motion is simulated as a single moving fluid. Solid objects inside the simulation domain can catch fire and start burning. Heat information is transferred from the fluid simulator ...

Sensor simulators can be used in forecasting the imaging quality of a new hyperspectral imaging spectrometer, and generating simulated data for the development and validation of the data processing algorithms. This paper presents a novel digital sensor simulator for the pushbroom Offner hyperspectral imaging spectrometer, which is widely used in the hyperspectral remote sensing. Based on the im...

Talk Abstract Many future multiprocessor servers will execute large commercial workloads, such as database management systems and web servers. Thus, simulations of new multiprocessor designs should run these workloads. However, simulating expensive servers running these large workloads on low-cost personal computers presents many challenges. Most of this talk discusses the Wisconsin Multifacet ...

This paper presents a 3D simulation environment for track systems in semiconductor fabrication. The track systems together with exposure tools carry out important functions of the photolithography process of semiconductor fabrication. The developed 3D track simulator can be used for design and evaluation of track systems, and their performance analysis. The main goal of the 3D track simulator i...

We design and validate simulators for generating queries and relevance judgments for retrieval system evaluation. We develop a simulation framework that incorporates existing and new simulation strategies. To validate a simulator, we assess whether evaluation using its output data ranks retrieval systems in the same way as evaluation using real-world data. The real-world data is obtained using ...
