An '''engineering validation test''' ('''EVT''') is performed on first [[engineering]] [[prototype]]s, to ensure that the basic [[unit]] performs to [[design]] goals and [[specifications]].

An '''engineering validation test''' (EVT) is performed on first [[engineering]] [[prototype]]s, to ensure that the basic unit performs to design goals and specifications.

==Tests==

Tests may include:

* [[Functional test]] (basic)

* Power measurement

* Signal quality test

* [[Conformance test]]

* [[Electromagnetic interference|EMI]] (EMI) pre-scan

* Thermal and 4 corner test

* Basic parametric measurements, specification verification

==Importance==

Identifying design problems, and solving them as early in the design cycle as possible, is the key to keeping projects on time and within budget. Too often, [[product design]] and performance problems are not detected until late in the [[product development]] cycle — when the product is ready to be shipped. The old adage holds true: It costs a [[Pennypenny (United States coin)|penny]] to make a change in engineering, a [[Dimedime (United States coin)|dime]] in production and a [[United States dollar|dollar]] after a product is in the field.

==Prototyping==

==Design verification test==

Design verification test (DVT) is an intensive testing program which is performed to deliver objective, comprehensive testing verifying all product specifications, interface standards, [[original equipment manufacturer]] ([[Original_equipment_manufacturer|OEM]]) requirements, and diagnostic commands. It consists of the following areas of testing:

* Functional testing (including usability)

* Performance testing

Line 27 ⟶ 26:

* Environmental testing

* Mechanical testing

* [[Mean time between failures]] ([[MTBF]]) prediction

* [[Conformance testing]]

* Electromagnetic compatibility ([[Electromagneticelectromagnetic compatibility|EMC]] (EMC)) testing and certification

* Safety certification

==Design refinement==

After prototyping, the product is moved to the next phase of the design cycle: [[iterative design|design refinement]]. Engineers revise and improve the design to meet performance and design requirements and specifications.
