University of Virginia Department of Electrical and Computer Engineering SEAS Accreditation Both EE and CpE programs are accredited by the Engineering Accreditation Commission of ABET, Inc. Criteria for accrediting engineering programs specify that curriculum must include: –One year of college-level mathematics and basic sciences –1.5 years of engineering topics »The engineering sciences have their roots in mathematics and basic sciences but carry knowledge further toward creative application. These studies provide a bridge between mathematics and basic sciences on the one hand and engineering practice on the other. »Engineering design is the process of devising a system, component, or process to meet desired needs. It is a decision-making process (often iterative), in which the basic sciences, mathematics, and the engineering sciences are applied to convert resources optimally to meet these stated needs. –General education component consistent with institution goals –Major Design Experience (often called capstone)

University of Virginia Department of Electrical and Computer Engineering SEAS Digital Logic Design Prof. Joanne Bechta Dugan

University of Virginia Department of Electrical and Computer Engineering SEAS The Digital World What kind of a world could we create if we restricted all questions to those with a yes/no answer? If every color was pure black or white, no shades of grey? If every aspect of our lives could be enumerated on a checksheet, each box checked or blank? If every decision was a clear-cut choice between two opposite alternatives? You might expect a boring world indeed, but in this course you’ll see how interesting such a digital world can be, since it includes such devices as computers, smartphones, pet tracking systems, fitbits and much more.

University of Virginia Department of Electrical and Computer Engineering SEAS Digital Logic Design Digital Logic Design is the process of designing complex digital systems using simple two-way switches, providing a physical device to answer yes or no. In this course we begin with binary (yes/no) phenomena and build successively more complex components and systems, ending with a simple processor. You will discover how simple gates are built from switches, how components are built from gates, how systems are built from components. At first we will assume that there is no concept of time and that everything we need to know is immediately available. This will allow us to design an interesting collection of useful devices. Then we will add the concept of time, from which the concept of memory will emerge, which will greatly expand the devices that we can design and use to create more complex systems. Our goal is to assemble a simple processor from the constituent components and to understand how software computations are performed on hardware.

University of Virginia Department of Electrical and Computer Engineering SEAS Learning Outcomes Upon successful completion of this course, you will be able to translate a real-world problem into precise specifications for a digital system, design a system to meet those specifications and demonstrate that your solution solves the problem. Further, you will be able to take a digital system that has already been designed and implemented and deconstruct and analyze it to determine what it does, how it works, and how you can use it in your system.

University of Virginia Department of Electrical and Computer Engineering SEAS Goals In this course you will: experience how electrical and computer scientists and engineers build digital systems improve your problem-solving skills, including design and debugging skills design in multiple levels of abstraction, that is, be able to move from detailed component-level design to system design (where components are treated as building blocks) and vice-versa appreciate the need for precision in technical communications, particularly with respect to interface design

University of Virginia Department of Electrical and Computer Engineering SEAS Course information Intro course, no prerequisites Required for EE, CpE, BSCS and BACS students 150 students per semester (offered every semester) 3 class meetings per week 5 lab assignments

University of Virginia Department of Electrical and Computer Engineering SEAS First Day of class Students are asked to prepare for the first class by Downloading Logisim software from Becoming familiar with 3 types of puzzles: –Word Squares –Sudoku –KenKen (Handout contains sample puzzles and in class activity for day 1)

University of Virginia Department of Electrical and Computer Engineering SEAS In-class activities Guided Explorations Karaoke Design LogisimFSM

University of Virginia Department of Electrical and Computer Engineering SEAS Guided Explorations Students are given a Logisim file containing several “mystery circuits” and a “guided exploration” They work with their neighbor to answer questions about the mystery circuit. The questions are intended to guide them through the process of discovering the function of the circuit. Often there are larger circuits to demonstrate how the mystery circuit is used. Usually there is an assignment to use the newly discovered knowledge in a design or to extend the mystery circuit in some non-trivial way.

University of Virginia Department of Electrical and Computer Engineering SEAS Karaoke Design Students are led through the design process for a complex circuit. Circuit contains some components arranged suggestively and the students fill in the connections to form a complete system that meets stated requirements. Example 1: multifunction counter Example 2: timer system

University of Virginia Department of Electrical and Computer Engineering SEAS RTL Design We extended the Logisim software package to facilitate exploration and design of RTL (Register Transfer Level) designs. RTL designs contain both a controller (FSM) and datapath. The outputs from one are the inputs to the other and vice versa. These systems can be quite complex and it is hard to understand the interrelationships between the two parts. LogisimFSM allows the controller to be expressed as a FSM rather than requiring full implementation into a circuit. Example 1: queue Example 2: full processor

University of Virginia Department of Electrical and Computer Engineering SEAS Success? Students appear to be more engaged and frequently tell me they are having fun. We are able to cover MORE material since incorporating the active learning techniques. The final exam for this class follows a standard format with similar questions year to year. Student performance on the tests and final exam was statistically identical to past semesters with one notable difference. More in-depth problems were given on those two troublesome topics. Students performed comparably on a more difficult exam. Instructor won three different teaching awards last year.

University of Virginia Department of Electrical and Computer Engineering SEAS Specific characteristics of a CpE major design experience Builds on knowledge contained in CPE curriculum Design should be an embedded computing system that address issues at the hardware/software interface, or the cyber/physical interface with aspects that address both sides Must include an interface that senses or actuates some physical phenomenon (not by a touch screen, mouse click, keyboard or direct messaging) and of course some computation One semester (fall)

University of Virginia Department of Electrical and Computer Engineering SEAS Some Concluding Thoughts Prof. Lloyd Harriott

University of Virginia Department of Electrical and Computer Engineering SEAS Using Undergraduate TA’s We’ve discovered several advantages to using undergraduate TA’s in the lab –Undergraduate TA’s have been through the same course and can relate to the current students better –Undergraduate TA’s are not conflicted between research and teaching as graduate TA’s can be –Peers can demand more of peers with less resentment (they are all in this together) –Undergraduate TA’s apply for the position and thus it can be seen as an honor to be asked to help –Undergraduate TA’s learn and retain the material better because of seeing it again as TA’s –Undergraduate TA’s become vested in the course and make suggestions for improvement from the student perspective
