Project approval
1, based on market feedback or customer demand, began to project project , project feasibility analysis.
2, to determine the name of the project, tentatively scheduled for "Dream 100", set up a project team dream of 100, to determine the project members.
3, project mission statement, general feature list including hardware and software feature list.
Technical Design
1, "Dream 100" project team met to discuss the project task analysis review.
2, according to the spirit of the meeting, members of the question and to determine the technical details, perfect and subdivision project tasks book.
3, hardware design , including schematic and PCB design, the design is completed and checked, archive After the check, the output file Schematic & PCB V1.0. Production archive file and re-output, comprising: PCB production package V1.0, BOM V1.0, SMT production package V1.0. Other output files, including: ID MD file, the procurement plan documents.
4, software design and output software version V1.0, V1.0 version of the archive, this software release is based on the development without hardware, generally transplant similar products and modify the code.
EVT (engineering validation)
1, product trial production, the design documents sent to the factory for production, the project team needs technical support for trial production, trial production of small quantity, usually about 100PCS, is mainly used to improve R & D testing and verification for software development.
2, product testing, software testing : functional testing. Structural tests : drop, waterproof, high temperature and other tests. Hardware testing : functional testing, test content is not the same for different products, communications products is divided into baseband and RF test.
3, the output of pilot reports, a general pilot report is given by the factory, the problem of reflected pilot report analysis and summary, improvements in the next production.
4, output software test reports, hardware test reports, production reporting tools , including FCT tools and software programming tools.
5, analysis of the problem to solve, output software version V1.1, V1.1 version output hardware, and possibly other versions, such tools version.
DVT (Design Verification)
V1.1 version of the hardware trial production after trial production stage, like to come back and EVT, testing, this version is mainly a problem of the return V1.0 and solve problems close, the relevant test report output, and the need to provide factory trial production report , view the last issue of whether the pilot appeared to improve.
PVT (small batch verification)
PVT stage small series production, this time the product features hardware and software is relatively stable, the number of general trial production at 1K or more, at this stage of production-related tools designed to optimize, optimize production processes, but also the return of the relevant issues and solve problems close.
Production stage
In this case "Dream 100 has 90% of the" amount of prenatal sort out all the problems, determine the amount of production of hardware and software versions and other documents, mass production.
