FAP ( Final Audit Proformance 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 thorough, 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。
=================================================================================
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 Stress 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
