Where I come from as a designer of integrated circuits:
Validation is the process to prove that the implementation matches the
description, i.e., the synthesized netlist will behave like the behavioral
description.
Characterization is the process to determine the operating range of the
physical device, i.e., clock rates, signal amplitude ranges, power supply
ranges, etc. Characterization tends to be run on a relatively small number
of devices and, so, does not take yield variation into account.
Qualification is the process to verify that each device (or a reasonable
yield) fabricated from a given design will meet its specifications.
Qualification takes yield, temperature, power supply effects into account.
Note, some specifications are internally generated and some are
"industry-standard", like EIA RS-232, PCI, DOCSIS, etc.

Subject: [SI-LIST] : Validation/Characterization/qualification
Can anybody know the definitions of:
Validation/characterization and qualification and when each one is used
(technically)
Thanks
