Hardware Engineer\'s Manual_Full_Chapter 1 Overview Section 1 §1.1.1 Basic Process of Hardware Development Hardware Development Process Introduction To develop a product hardware project, the first thing is to clarify the overall hardware requirements, such as CPU processing power, storage capacity and speed, I/O port allocation, interface requirements, level requirements, special circuit (thick film, etc.) requirements, etc. Secondly, formulate a hardware overall plan based on demand analysis, seek technical information, technical methods, and technical support for key components and circuits, and consider technical feasibility, reliability, and cost control more fully, and put forward clear requirements for development and debugging tools. Request samples of key components. Third, after the overall plan is determined, make detailed designs of hardware and single-board software, including drawing hardware schematics, single-board software functional block diagrams and coding, PCB wiring, and complete the development of the bill of materials, new device coding application, and material application. Fourth, after receiving the PCB board and materials, the welder will weld 1 to 2 single boards, debug the single board, debug each function in the principle design, and modify the schematic diagram if necessary and make records. Fifth, the joint debugging of hardware and software systems. General single boards require the cooperation of hardware personnel and single board software personnel. Special single boards (such as motherboards) require the development of relatively large software, and more software personnel are involved in the joint debugging. Generally, after the single board is debugged, there are some adjustments in the principle and PCB wiring, and a second board is required. Sixth, internal acceptance and transfer to pilot, the hardware project completes the development process. §1.1.2 Standardization of hardware development The basic process of hardware development in the previous section should be executed in accordance with the hardware development process specification documents. Not only that, hardware development involves the application of technology, the selection of devices, etc., and must follow the corresponding standardized measures to meet the requirements of quality assurance. This is mainly reflected in the fact that the adoption of technology must be reviewed by the overall group, the selection of devices and manufacturers must refer to the relevant documents of the material certification department, and the development process must complete the corresponding prescribed documents. In addition, commonly used hardware circuits (such as ID.WDT) must adopt a common standard design. Section 2 §1.2.1 Responsibilities of hardware engineers Responsibilities and basic skills of hardware engineers A hardware platform with leading technology and reliable operation is the foundation of the company\'s product quality. The responsibilities of hardware engineers are sacred and the responsibilities are heavy. yf-f4-06-cjy 1. Hardware engineers should be brave enough to try new and advanced technologies in product hardware design...
