TEST LEVELS
1. Production test at room temperature and nominal supply voltage
with guardbands for supply and temperature ranges.
2. Production test at room temperature and nominal supply voltage
with guardbands for supply and temperature ranges using
correlated test.
3. Production test at room temperature and nominal supply
voltage.
4. QA sample test.
5. Calculated result based on Level 1, 2, or 3.
6. Not tested. Guaranteed by design simulations.
7. Not tested. Based on characterization of nominal parts.
8. Not tested. Based on existing design/characterization data of
similar product.
9. Indirect test.
