DefinitionSystem Design Process

• Requirements Specification
• Conceptualization
• Analysis
• Synthesis
• Verification
• Documentation

4746 System Design Process

• Requirements Specification
• Given by me HW, Project, Exam, etc.
• Conceptualization
• Developed by you and your group
• Iteration Design Cycle
• Write Program
• Compile Program
• Debug Compilation Errors
• Examine output results
• Debug Logical Errors
• Examine hardware results
• Debug Hardware Errors

Iteration

4746 System Design Process

• Documentation
• Digitally dropped into Blackboard Site

This could take one hour or thirty hours
depending on your skills. I will help you avoid
landmines

Homework Assignments

• Two weeks to complete an assignment
• No excuse for network down, printer out of
  toner, computer locks up, etc.
• HW assignments will overlap
• Average one assignment due every 1 ½ weeks.
• HWs will build upon one another
• You may use solutions from previous HWs
• Homework assignments will be customized
• Solutions will be given for a general problem
• You must have working program for full credit

10
Homework Assignments

• HWs are self-correcting for the right
  answer.
• Ill check for the correct solution.
• HW must be on time
• Digital Drop Box (time stamped)
• Both you and your partner must digitally submit
• Only one copy of handwritten notes needed.

11
Design Projects

• Design projects DO NOT replace regular homework
  assignments.
• You may have both due during the same week.
• Hardware MUST work for more than ½ credit

12
Quizzes

• Designed to keep you awake.
• Mostly group quizzes
• Some individual quizzes
• No make-up quizzes will be given
• Used to monitor attendance
• I will drop the three lowest quiz grades

13
Course Notes

• All slides will be available online
• Exam, HW, and Quiz solutions online

14
EEL-4746Best Practices

• Keep up with the course!!!
• Complete the Assignments!!!
• You will be allowed to work in groups, but

15
The only way to learn to code in Assembly
Language is to code in Assembly Language.

Design Methodology
21
Definition Engineering Design Methodology

• A systematic approach to achieve the desired goal
  of a solution to the problem (i.e. a working
  design) using proven principles or practices.
• You must follow our 4746 design methodology to
  get full credit.

22
Design Methodology
23
Design Abstraction

• How do we describe a system?

24
Design Abstraction
Example Design a system which will complement
input A
A
F(x)
where A and Y are single bit values
We can describe this design using a logical
Truth Table
A Y
0 1
1 0
25
Levels of Design Abstraction
Our goal in ECE is physical or hardware
implementations of the design.

In ECE, we design at several levels of
abstraction

Summary

• All levels give you the same result.
• We will learn how to use the system level to
  its highest degree of effectiveness.
