The existing power supply design flow comprises more low-level repetitive work, the work efficiency is seriously reduced, the design consistency, the design quality consistency and the test result consistency cannot be ensured, and the optimal design cost of a scheme cannot be ensured. The following analysis will be made in terms of efficiency, quality and cost: the first reason is that the efficiency is low: (1) chip type selection: the types of power supply chips are more, and the chip type selection wastes time; (2) circuit design: different items need to be redesigned, and the circuit design reuse rate is low; (3) PCB layout and wiring: different project PCBs need to be re-arranged, more time is consumed, and the PCB arrangement reuse rate is low; 2. the design consistency can not be ensured, and the design quality consistency is caused by: (1) chip type selection: the power supply chips are more in variety, and the chip selection depends on the design habit of engineers; (2) circuit design: the principle and scheme design cannot be consistent due to the difference of the design concepts of engineers, and the design quality cannot be ensured; (3) PCB layout and wiring: because the design habits of a PCB layout engineer and a power supply design engineer are different, optimal layout and wiring cannot be guaranteed; 3. reasons for not guaranteeing the cost optimum: (1) material selection: the materials are various, and the optimal cost of the selected materials cannot be guaranteed on the premise of meeting the design requirements.
Therefore, it is desirable to provide a power supply module design method and apparatus for overcoming the above-mentioned drawbacks of the prior art.
