Hollot, Department Head Electrical & Computer Engineering ABSTRACT A NOVEL APPROACH TO PCI SIMULATION USING SCRIPTSIM MAY 2008 KEVIN ANDRYC, B.S., UNIVERISTY OF MASSACHUSETTS M.S.E.C.E., UNIVERISTY OF MASSACHUSETTS Directed by: Professor Russell G. Tessier In recent years, the Peripheral Component Interconnect (PCI) has become one of the most widely used bus architectures in modern computers. Simulation of the PCI bus, however, has been limited in both research and development. Current commercial PCI simulation software is designed towards compliance and verification testing rather than accurately mimicking PCI bus systems. In addition, most PCI simulation software is inflexible and offers no graphical user interface, instead relying on text files for configuration. This paper presents a novel approach to PCI simulation using ScriptSim, an open- source PCI simulation tool that supports all the features offered by the PCI Local Specification Version 2.2. In addition to extending ScriptSim to include PCI-X functionality and a web-based graphical interface, we introduce techniques that allow us to accurately simulate real-world systems. iv TABLE OF CONTENTS Page ABSTRACT ..................................................................................................................... iv LIST OF TABLES ........................................................................................................... ix LIST OF FIGURES ......................................................................................................... xi CHAPTER 1.
