This course will discuss the principles of signal integrity and its applications in the proper design of high-speed digital circuits. As interconnect data rates increase, phenomena that have historically been negligible begin to dominate performance, requiring techniques that were not previously necessary. This course is designed to give the students the theoretical and simulation tools needed to determine where signal integrity issues may arise, how to prevent such problems, and how to resolve problems when they arise in practice. A partial list of topics includes distributed circuits and lossless transmission lines, nonideal transmission line effects, crosstalk mitigation, differential pairs and modal analysis, I/O circuits and logic standards, and signal coding and waveshaping techniques.
Thorough knowledge of digital design and circuit theory. Prior coursework in electromagnetics and Laplace transforms will be helpful.
To understand the fundamentals of high speed signal propagation in circuits and cables. To be able to apply this knowledge to determine where signal integrity issues may arrise and how to solve problems of poor digital signal integrity.
To use hand calculations to solve propagation and termination problems on lossless and low-loss transmission lines for digital circuits.
To understand how the physical layout of signal and return paths affect transmission line characteristics including characteristic impedance, propagation skew, and cross talk.
- To use signaling and coding strategies to improve signal integrity in high-speed serial links.
To use computer simulations with SPICE and HyperLynx to analyze singal integrity problems.

Student Assessment Criteria
Students are expected to do their own homework. Homework is due at the beginning of the next class after it is assigned. The homework solutions will be presented in class after it is collected so no late homework will be accepted. Assignments will be graded and returned the following week.
A grade of A indicates achievement of consistent excellence and distinction throughout the course—that is, conspicuous excellence in all aspects of assignments and discussion in every week.
A grade of B indicates work that meets all course requirements on a level appropriate for graduate academic work. These criteria apply to both undergraduates and graduate students taking the course.
100-90 = A
89-75 = B
74-65 = C
<65 = F
Computer and Technical Requirements
Students should be proficient in solving simple circuit problems (RLC circuits). Students should have fundamental computer skills and be able to learn the use of simulation programs. Students should have some basic knowledge of electromagnetics.
There will be weekly homework assignments.
Exams will be in-class, closed book, but open notes. Calculators will be permitted.
During the lectures, the instructor will ask questions of the class. Students will not usually (but may occasionally) be singled out for a response, so everyone should try to participate. These lecture questions serve two functions: to gauge the student's understanding of the presented material to see if more background or recapitulation is needed, and to gauge student's willingness and ability to think about the problems at hand.
Textbook information for this course is available online through the MBS Direct Virtual Bookstore.
There are no notes for this course.
