The invention belongs to the technical field of a circuit board, and provides a design method and system for applying a USB HUB chip to a circuit board. The circuit board comprises a peripheral circuit; the design method comprises the following steps of A, dividing the circuit board into multiple blocks according to hardware functions of multiple ports of the USB HUB chip; B, manufacturing the USB HUB chip into packaging specification according to the multiple blocks and arranging the chip on the circuit board; and C, enabling the peripheral circuit to be connected with the multiple blocks. Therefore, by means of dividing the circuit board into multiple blocks according to hardware functions of the multiple ports of the USB HUB chip, and manufacturing the chip into packaging specification and arranging the chip on the circuit board, when another USB HUB chip needs to be replaced, the replacement can be realized by only re-connecting the multiple ports with corresponding multiple blocks according to the hardware functions of multiple ports of another USB HUB chip, without needing to replace the whole circuit board, so that the circuit product design time is reduced, and efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of circuit boards, in particular to a design method and system for applying a USB HUB chip to a circuit board. Background technique [0002] At present, for products with USB HUB (universal serial bus hub) functions, such as USB HUB chips, the common design is to directly solder the USB HUB chip on the PCB (Printed Circuit Board, circuit board), and then connect the peripheral The circuit can realize the USB port expansion function. However, the technical update and problem solving of USB HUB chips are relatively fast, and products need to be iterated quickly; at the same time, USB HUB chips produced by different manufacturers will also have compatibility problems. Once the USB HUB chip has a problem or needs to be upgraded, the entire circuit board needs to be replaced, resulting in increased development efforts and increased development costs. [0003] Therefore, in the prior art, when the USB HUB chip h...
