Shorts and open test on voltage rails
Basic confirmation of functionality & 'Board Bring Up'
Basic power test supplies for stability and spec
Measure clocks & oscillators
If firmware available, program devices
Start test jig spec during this phase
REV A
Fix the first issues identified in Prototyping stage. Additional features check. Expand areas of test.
