8、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
9、late in the product development cycle when youre 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 th
10、e 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. Percepts proven EVT
11、 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 prot
