Tools
• Goal: Non-obsolete, good fit, in-stock !
• Warning: It takes time! (Estimate 1-2 weeks) !
• Google! !
• PDF datasheets !
• NDAs
Part Selection
• Goal: To convert design intent into CAD files !
• Re-create parts in CAD !
• Block diagram —> schematic !
• More part selection !
• Floorplan estimate !
• Schematic —> layout
Design
• Goal: Don’t prototype a dud !
• Design rule checking !
• Simulation !
• Design review !
• Spot checking
Verification
• Goal: Confirm CAD file before MFG !• Goal: Give software a prototype to dev against
!• Bundling CAD files
!• Ordering quick turn - low volume
!• Waiting
!• Turn-on testing & bring up
Prototyping
• Are all the parts placed? !
• Shipping damage? !
• Measure power & ground impedance !
• Plug in !
• Turn-on !
• Let the smoke out
