1, engineering verification test:
Design verification in the initial stage of product development. When the designer realizes the sample, he will do the initial test and verification, including functional and safety tests. In general, RD will fully verify the samples. Because it is a sample, there may be many problems, and the test may be done n times.
2. Design verification test:
After solving the problem of the sample in EVT stage, the level and time sequence of all signals were tested, and the safety test was completed, which was verified by research and development and DQA. At this time, the product is basically finalized.
3, small batch process verification test:
Verify the realization of various functions of the new model and test its stability and reliability.
4. System verification test:
The purpose is to simulate a series of real test scenarios that customers may encounter, so as to analyze possible problems or errors. SVT can use test scripts or have SVT teams execute them.
5. Mass production:
According to different product forms and requirements, each company will also insert other links, such as: basic verification test, maturity verification, mass production verification test and so on.
R&D classification:
1, theoretical research and development:
Theoretical research and development, new theoretical research, and new theoretical knowledge points. For example, the research and development of gate metal of IC chip unit transistor. R&D does not involve specific practical product application fields, but theoretical research and new content. Another example is drug research and development, including the process of drug selection, clinical application and drug listing.
2. Product development:
Product research and development is the content of products actually manufactured and developed. For example, any visual consumer goods are product development. Product research and development is the survival foundation of manufacturing enterprises. If an enterprise has no product research and development, it is simply an agent to short the box, with very low profit and very little living space.
