Build guide
EVT vs DVT vs PVT
Teams mix these gates. Factories then discover thermal or vision drift that EVT should have caught.
EVT proves the integrated prototype works. DVT proves the frozen design across units and stress. PVT (pilot production) proves the line can build to spec. AI hardware adds inference load, camera lot variation, and OTA rollback to each gate.
| Gate | Question | AI-specific checks |
|---|---|---|
| EVT | Does it work? | Thermal under GPU load, sync, model pin |
| DVT | Does the design meet spec? | Multi-unit vision spread, vibe/drop class |
| PVT | Can the line build it? | Yield, EOL test = EVT scripts |
