The Design Process

Analysis Think – what should the final design do? List customer requirements Consider constraints – balance tradeoffs Define specifications How will you know if it works? How will you test it?

Requirements Review Validate the specifications Will the requirements be satisfied?

Synthesis How can each goal be accomplished? Make basic decisions to arrive at a possible solution Look at what impact each decision will have on other parts of the system

Technical Design -- Concept-- Partition into functional modules and define the operation of each Do circuit design and/or software design for each module – at least in concept Integrate modules into system Document design so far

Go back to synthesis step and repeat several times Evaluation/Decision Review design – does it meet specifications? Is it reasonable? …….. Go back to synthesis step and repeat several times ……... Compare different concept designs Pick overall best solution

Proposal

High-level Design Review

Prototyping Build Test – does it work to specifications?

Evaluation Review as-built design Does it meet all specifications? Is it reasonable?

Technical Design Review

Documentation Gather details Prepare complete final engineering design report

Final Presentation

??? Acceptance ???
