11. Course rules and general comments • Examinations are closed book, and closed notes. • Homework assignments are generally from the text book and are given on a weekly basis; the due date is one week from the distribution date (unless otherwise specified). No late homework solutions will be accepted except under extreme non-academic conditions with the prior approval of the instructor. • Any disputed grade must be resolved within 7 days of the return of the graded item.  All your course work (homework, project, quiz and exams) is expected to be your own. Lecture #1

12. Evidence indicating copying of work or other cooperation will be dealt with based on the University academic conduct rules. General instructions such as assisting in problem interpretation, and giving occasional hints on problem attack (i.e., the kind of help you would get from the instructor in the course!), however, are permitted. On the other hand, you are encouraged to form informal study groups to solve homework problems. You are responsible for all the course materials and all lecture contents unless specified otherwise by the instructor. If you miss a class, it is your responsibility to obtain assignments and other information given on that day.If you have questions on course materials, the instructor will be available for consultation. Please try to get answers before serious difficulties in your understanding of course material arise. In particular, it is much better to get your questions answered before an exam than after! Lecture #1

13. Please pay attention to the following requirements regarding your homework assignment Always use standard size (81/2  11) paper. Do not use torn-off paper from spiral bound notebooksWrite the course #, homework #, and your name on top of the first page, as shown below Course #Homework #Your NameWrite clearly, neatly and in an orderly fashion.Draw block schematics, circuit diagrams, layout etc. when applicable·Show all steps. No credit may be given for the work not shown.Staple all homework pages together Lecture #1

14. Project Guidelines Late projects will not be accepted. If your project is not complete by the due date, you should hand in the incomplete project for a partial credit. Project reports should be professionally documented. Use a word processor to document your work. Your report should be properly placed in a folder. Your report should be free of grammatical and spelling errors. Your project should reflect your own work. If unreasonable similarities are recognized between the submitted project reports, they will receive failing grades. Lecture #1

16. Overview • Background VLSI has its beginning back in the early 60's with SSI, small scale integration, when a few bipolar transistors and resistors were fabricated on the same chip. Today chips are both simpler and more complex. They typically only contain two active elements (NMOS and PMOS transistors) and wires. But there might be millions of these transistors on the chip, and these chips can do amazing functions. Nowadays we find chips in everything. We will look at why this has happened and what is novel about VLSI design. We will also take a quick look at the basic elements that make up VLSI chips: MOS transistors and wires. Lecture #1
