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 cyc le as possible, is key to keeping your project on time and within budget. T oo often, product design and performance problems are not detected until la te in the product development cycle —when you’re getting ready to ship yo ur 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 f ield.
In the Prototyping stage, engineers create actual working samples of th e product they plan to produce. Engineering Verification Testing (EVT) is u sed on prototypes to verify that the design meets pre-determined specificat ions and design goals. This valuable information is used to validate the de sign 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 produ ct 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 t esting verifying all product specifications, interface standards, OEM requi rements, and diagnostic commands.
Percept’s thorough, objective DVT methodology delivers objective, comp rehensive 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 Test ing Reliability Testing Compliance Testing
Process (or Pilot) Verification Test (PVT)
Subset of Design Verification Tests (DVT) Performed on pre-production o r production units Verifies design has been correctly implemented into prod uction

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。
======================================================================= ==========
EVT: Engineering Verification Test
工程验证测试
产品开发初期的设计验证。设计者实现样品时做初期的测试验证，包括功能和安规测试，一般由RD(Research&Development)对样品进行全面验证，因是样品，问题可能较多，测试可能会做N次。
DVT: Design Verification Test
设计验证测试
解决样品在EVT阶段的问题后进行，对所有信号的电平和时序进行测试，完成安规测试，由RD和DQA(Design Qualiy Assurance)验证。此时产品基本定型。
DMT: Design Maturity Test
成熟度验证
可与DVT同时进行，主要极限条件下测试产品的MTBF(Mean Time Between
Failure)。HALT(High Accelerated Life Test）&HASS(High Accelerated Stres s Screen)等，是检验产品潜在缺陷的有效方法。
PVT: Pilot-run Verification Test
小批量过程验证测试，
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。
MVT: Mass-Production Verification Test
量产验证测试
验证量产时产品的大批量一致性，由DQA验证。
MP: Mass-Production 量产
