2. 2 ECE 415-416 SDP Outline  Overview: Senior Design Project 2007 – SDP07  What is Design?  ECE 303 Assignment: SDP07 Project Description

3. 3 ECE 415-416 SDP Overview

4. 4 ECE 415-416 SDP Overview ECE 415 - Principles of engineering design process. Small groups of students design computer/electronic systems to specifications. Preliminary paper design followed by hardware or software prototype. Students must complete project in ECE 416. Prerequisites: ECE 313, ECE 323, and ECE 353. ECE 416 - Continuation of ECE 415. Design of small computer/electronic system built, refined, tested, and demonstrated. Final prototype shown to meet initial specifications. Final design review. Prerequisite: ECE 415.

8. Department of Electrical and Computer Engineering What is design?

9. 9 ECE 415-416 SDP What is design?  Engineering Science vs Engineering Design  Engineering Science >>> theory (Ohm’s Law)  Engineering Design >>> application of theory (Telegraph)

10. 10 ECE 415-416 SDP What is design?  Engineering Design is characterized by… 1. Application of theory 2. Solving of open-ended problems >>> a problem with a multiplicity of possible solutions 3. Working towards a specific end, a product

11. 11 ECE 415-416 SDP What is design? Restating things a bit…  Engineering Science can thought of a set of truths or fundamental principles  Engineering Design can be thought of as a process. A process by which, theory (scientific truths) is applied towards the creation of a specific product or service which satisfy the stated needs of a client.

12. 12 ECE 415-416 SDP What is design? Thomas Edison (1847-1931) vs. Nikola Tesla (1856-1943)

13. 13 ECE 415-416 SDP What is design? Let’s think about design in the context of a fictional product…

14. 14 ECE 415-416 SDP What is design? iRec

15. 15 ECE 415-416 SDP What is design?  Designing the iRec

16. 16 ECE 415-416 SDP What is design? The iRec a portable monophonic solid-state digital audio recorder

17. 17 ECE 415-416 SDP What is design?  What theory (engineering science) would we need to know in order to design a portable monophonic solid-state digital audio recorder? Any ideas?

18. 18 ECE 415-416 SDP What is design?  What theory would we need to know in order to design iRec, a portable monophonic solid- state digital audio recorder? The theory (engineering science) of… >> sound / acoustical energy >> microphones / acoustical transducer >> low-noise audio amplifiers >> analog to digital converters (ADCs) >> microprocessors / monolithic stored-program computer …

19. 19 ECE 415-416 SDP What is design?  In order to design the iRec, we’ll need… the engineering science of… >> sound / acoustical energy >> microphones / acoustical transducer >> low-noise audio amplifier >> analog to digital converter >> microprocessors >> Flash EEPROM >> ergonomics / human-machine interface >> digital to analog converters >> audio power amplifier >> digital data transfer system

20. 20 ECE 415-416 SDP What is design? [ Which sub-areas of the ECE universe do you want to learn more about? ]

21. 21 ECE 415-416 SDP What is design?  In a large company, each of the previous sub- system areas would most likely have its own design team.  Each team would follow a similar process… 1. Identify Needs 2. Write a Technical Specification 3. Create a “paper” design, considering design alternatives 4. Build a prototype 5. Refine the design 6. Test integration with other sub-systems 7. Send final design to manufacturing team

22. 22 ECE 415-416 SDP What is design? Let’s consider a small part of the iRec design…. the selection of the iRec’s main microprocessor…

23. 23 ECE 415-416 SDP What is design? The important characteristics of the iRec’s main microprocessor… > low cost > low power > appropriate speed > small size > availability > prog. language support > compatibility with automated manufacturing techniques > familiarity to team members

24. 24 ECE 415-416 SDP What is design? In ECE 415 you would present your microprocessor selection to your advisor and team members for review in the weekly meetings. Review meetings common in industry

25. 25 ECE 415-416 SDP What is design? The SDP Design Process 1. Identify Needs/Wants 2. Write a Technical Specification 3. Create a “paper” design, considering design alternatives 4. Build a prototype 5. Refine the design 6. Test integration with other sub- systems 7. Complete final prototype
