工厂/设计产品测试：

BVT是Build Verification Test，基本验证测试，对完成的代码进行编译和连接，产生一个构造，以检查程序的主要功能是否会像预期一样进行工作。

EVT是Engineer Verification Test，工程样品验证测试。

DVT是Design Verification Test的简称，设计验证测试，是硬件生产中不可缺少的一个检测环节，包括模具测试、电子性能、外观测试等等。

PVT全称为Process Verification Test，意为小批量过程验证测试，硬件测试的一种，主要验证新机型的各功能实现状况并进行稳定性及可靠性测试。

Engineering Verification Testing (EVT)

Identifying design problems and solving them as early in the design

cycle as possible, is key to keeping your project on time and within budget. Too often, product design and performance problems are not detected until late in the product development cycle —when you’re getting ready to ship your product. The old adage holds true: Its costs a penny to make a change in engineering, a dime in production and a dollar after a product is in the field.

In the Prototyping stage, engineers create actual working samples of the product they plan to produce. Engineering Verification Testing (EVT) is used on prototypes to verify that the design meets pre-determined specifications and design goals. This valuable information is used to validate the design as is, or identify areas that need to be modified.

Percept’s proven EVT testing process helps clients to quickly identify and resolve design issues early in the design cycle, improving future product performance while saving time and money.

EVT:

Consists of basic functional tests, parametric measurements, specification verification Is performed on first engineering prototypes Ensures basic unit performance to design goals and specifications

DVT / EVT

Design Verification Testing (DVT)

After prototyping, the product is moved to the next phase of the design cycle: Design Refinement. Engineers revise and improve the design to meet performance and design requirements and specifications. Design Verification Testing is performed to deliver objective, comprehensive testing verifying all product specifications, interface standards, OEM requirements, and diagnostic commands.

Percept’s thoro ugh, objective DVT methodology delivers objective, comprehensive testing to verify all product specifications, interface standards, OEM requirements, and diagnostic commands.

DVT is an intensive testing program consisting of five areas of testing: Functional Testing (including usability) Performance Testing Climatic Testing Reliability Testing Compliance Testing

Process (or Pilot) Verification Test (PVT)

Subset of Design Verification Tests (DVT) Performed on pre-production or production units Verifies design has been correctly implemented into production

CVT Compatibility Verification Testing

产品定义(EVT)、产品设计(DVT)，到定型测试(PVT)三大阶段是系统化产品研发流程。70?!&

DVT ：Design Verification Test，是由开发样机阶段向生产样机阶段转换所必须的技术评审,

DVT阶段：指从EVT评审通过后到DVT评审的阶段。包括模具测试、电子性能、外观测试等.

重点是确认：1、是否符合产品定义要求，2、可否批量生产，由项目部输出评审报告。

PVT：Production Verification Test，是由生产样机阶段向量产阶段转换所必须的技术评审,

PVT阶段：指从DVT评审通过后到PVT评审的阶段。主要验证新机型的各功能实现状况并进行稳定性及可靠性测试。

重点是确认：能否量产，由项目部输出评审报告。
