Course Description:

This is the introductory course in VLSI where you will learn how to drive Electronic Design Automation (EDA) Computer-Aided Design (CAD) tools. With them you will learn the physical mask design for transistors and how to create and characterize your own logic cell library. You will then use your cell library to design a complete integrated circuit architecture including power delivery and bonding pads.

Many aspects of Digital VLSI design will be introduced in order to take this significant and enjoyable design journey. However, note that this is not a course in digital system design or computer architecture. You will already need to know Verilog, boolean logic, and how to design and implement combinational and sequential digital circuits (such as adders and other datapath logic, and finite state machines). The project will also require some knowledge of computer architecture for you to complete a moderately large digital design. We recommend you take ECE/CS 3810 (Computer Architecture) before this course.

Topics that will be covered in lectures include:

The class will require extensive use of CAD tools. All of the CAD tools required will be available in the CADE lab. Students must have an account that will allow them to use the CADE machines. These tools do not run on MS Windoze. Therefore some familiarity with various versions of Unix (such as Linux or Solaris) and the X window system is required for this course.

The tools will be discussed in class and you will receive the aid of the TA in the labs and project. However, there is no specific lab class that you are required to attend. You can perform the labs and your project at your own convenience, either in the CADE lab at the University, or across the network. Remember that nothing can replace taking the time to read the CAD tool documentation.

Integrated circuit design is mastered only through experience, so this is a hands-on course with lots of labs and project time. The homework, as well as lectures, will be closely tied to the term project, the design of a simple standard cell library and then the use of that library to design a project. The final library and project will be done in teams (preferably made up of 3 to 4 students). The initial design of cells for the project will be done individually. You must complete the design of these cells on time. You are encouraged to interact with others, but until you are asked to form teams, the work on your cell designs, simulations, etc., must be independent and fully your own work.

Fabrication of your final project is possible thanks to the research funding provided through the MOSIS service. Few tasks are more rewarding than creating a functional integrated circuit. However, few tasks are also more disappointing that spending time on the design of an integrated circuit only to have the fabricated circuit return non-functional. Therefore, careful design practices must be followed if you are to fabricate your chip including sufficient Design-For-Test, validation of your design, and a quality design review. If you do fabricate the chip, you will be required to take ECE/CS 6712 in the spring to test and report on the results. 6712 is a fun class and a reward to those who make the effort to fabricate their designs.

Required Textbooks:

  o   Principles of CMOS VLSI Design: A Circuits and Systems Perspective (4th Edition), By Neil Weste and David Harris. Published by Addison-Wesley, c2010, ISBN 0-321-54774-8.
Get the errata (mistakes) for the textbook.

  o   Digital VLSI Chip Design with Cadence and Synopsys CAD Tools, by Erik Brunvand. Published by Addison-Wesley, c2010 ISBN 978-0321547996
Note: The there is an update for the book to map from the version 5 to version 6 of the Cadence design tool interfaces. You will need to use this in conjunction with the book to efficiently use the tools.

The Brunvand book is the "lab manual" for the course. Prof. Brunvand has made a few draft chapters of this book available to students taking this course which are similar to the published book. Please respect the copyright of these chapters and do not distribute or make them available on the web. These chapters are only accessible from the web domain.

Course Mailing Lists:

There are two class mailing lists, and The 5710 list will be used to send out important information to everyone in the class. Please use discretion when sending messages to the entire class. Mail sent to teach-5710 just goes to the instructor and TA. This is the preferred method of communicating with the TA and instructor.

The lists will be automatically populated with your university mailing address. If you would like to add another e-mail address, you can send a subscribe request by logging on to the UofU sympa mailing list server. Let me know if you would like to remove your university e-mail address in lieu of another preferred address.

Grading Policy:

Refer to the College of Engineering Guidelines for more detail on appeals, disabilities, adding, and withdrawing from courses.

Incomplete Policy:   You can't get an incomplete unless you have a documented medical or legal emergency.
Add/Drop Policy: The standard University Policy is applied.
Disability: If you have a condition that merits consideration, you must contact the instructor at the beginning of the course.

The homework will take the form of problem sets, project proposals, and other written work. The Labs will involve using the VLSI CAD tools to design the mask work and layout of cells that will be used in your project. The class project will require the design of a small digital standard cell library that will then be used as a cell library for a moderate sized functional design. Class members will join design teams for the implementation of the design. The design review will consist of a short presentation of the project to the class. The project report will be a paper in conference or journal format.

Those taking the graduate level course will have additional requirements that include a more rigorous project or design flow and the review of one or more papers relating to VLSI from journals or conferences in the area. These could be related to the project being implemented.

Details on the requirements for your project reports. Please refer to my links for 6712 and 6770 for example reports students have delivered in previous years.

Homework Assignments:

The labs and homework build upon each other during class.
These need to be completed on-time! There is no general provision for late work.

Labs must be tar'ed up and e-mailed to the TA mailing list.
There will be seven labs in this course as follows:
