The history of computers starts out about 2000 years ago, at the birth of the abacus, a wooden rack holding two horizontal wires with beads strung on them. When these beads are moved around, according to programming rules memorized by the user, all regular arithmetic problems can be done. Another important invention around the same time was the Astrolabe, used for navigation. Blaise Pascal is usually credited for building the first digital computer in 1642. It added numbers entered with dials and was made to help his father, a tax collector. In 1671, Gottfried Wilhelm von Leibniz invented a computer that was built in 1694. It could add, and, after changing some things around, multiply. Leibniz invented a special stepped gear mechanism for introducing the addend digits, and this is still being used.

Niklaus Wirth of the Swiss Federal Institute of Technology {ETH] waspresented the 1984 ACM A. M. Ihring Award at the Association’s Annual Conference in San Francisco in October in recognition of his outstanding work in developing a sequence of innovative computer languages: Euler’ ALGOL-W, Modula, and Pascal. Pascal, in particular, has become significant pedagogically and has established a foundation for future research in the areas of computer language, systems, and architecture. The hallmarks of a Wirth language are its simplicity, economy of design, and high-quality engineering, which result in a language whose notation appears to be a natural extension of algorithmic thinking rather than an extraneous formalism.

This document is a short introduction to working with COVISE. It is primarily a tutorial for COVISE novices. It doesn’t cover advanced topics such as the development of new application modules or the installation and configuration process. We assume that you have a running COVISE on your machine. For installation guide read the files README and INSTALL.TXT which come with your COVISEdistribution. For developing new application modules read the COVISE Programming Guide.

1. First determine the best way to analyze the system. (Note: This is possibly the hardest step in the entire design system depending on what you are trying to design the image for.)
a. If the system has a CD-ROM drive or is capable of running Windows XP/2000 then the program tap.exe will be used to create the *.pmq file.

GNS3 is a Graphical Network Simulator that allows emulation of complex networks. You may be familiar with VMWare or Virtual PC that are used to emulate various operating systems in a virtual environment. These programs allow you to run operating systems such as Windows XP Professional or Ubuntu Linux in a virtual environment on your computer. GNS3 allows the same type of emulation using Cisco Internetwork Operating Systems. It allows you to run a Cisco IOS in a virtual environment on your computer. GNS3 is a graphical front end to a product called Dynagen. Dynamips is the core program that allows IOS emulation. Dynagen runs on top of Dynamips to create a more user friendly, text-based environment. A user may create network topologies using simple Windows ini-type files with Dynagen running on top of Dynamips. GNS3 takes this a step further by providing a graphical environment.

Note: The Yellow LED will flash when the unit is transmitting data from the computer to the controller. The Green LED will flash when the unit is receiving data from the computer to the controller. There is no power on LED indicator. Look in your Device Manager to see if the USB485 card shows up under one of the COM Ports. This is a clear indication that the unit is in good condition and is ready to communicate.
