Title: Automatic Modeling and Simulation of Networked Components
Department: Master of Science in Electrical and Computer Engineering
Project Intro: This chapter introduces the problem that this thesis addresses and the motivating reasons why this work is needed. Previous work in the eld of automatic model generation and software- and hardware-in-the-loop simulation is reviewed. The con- tributions and innovations introduced in this thesis are described and the layout of the thesis is outlined.
Abstract: This thesis proposes to solve these issues by presenting a method to automatically generate a simulation model and run a random walk simulation using that model. The method is automated so that a modeler spends as little time as possible creating a simulation model and the errors normally associated with manual modeling are eliminated. The simulation is automated to allow a human to focus attention on the
device that should be tested. The communications transactions between two nodes on a network are recorded as a trace le. This trace le is used to automatically generate a nite state machine model. The model can be adjusted by a designer to add missing information and then simulated in real-time using a software-in-the-loop approach. The innovations in this thesis include adaptation of a synthesis method for use in simulation, introduction of a random simulation method, and introduction of a practical evaluation method for two nite state machines. Test results indicate that nodes can be adequately replaced by models generated automatically by these methods. In addition, model construction time is reduced when comparing to the from scratch model creation method.
