Embodiment Construction
[0075] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0076] First, the relevant software or concepts involved in the embodiments of the present application are introduced:
[0077] Power Distribution Network (PDN) refers to the physical circuit that transmits power from the power source to the load. The current flows from the power source to the load through the PDN, and then flows from the load back to the power source through the PDN. The board-level PDN mentioned in the present inventio...

The invention provides a decoupling capacitor selection method and device, a server and a readable storage medium, and is applied to the technical field of computers, and the method comprises the steps: calculating the actual impedance of a board-level PDN operating at any working frequency in a preset working frequency band according to the design parameters of the board-level PDN, and calculating the actual impedance of the board-level PDN based on a preset impedance threshold value; a first target frequency band is determined in a preset working frequency band, and first decoupling capacitors corresponding to the first target frequency band and a first number of the first decoupling capacitors are determined based on the endpoint frequency of the first target frequency band and a preset impedance threshold. According to the method for automatically selecting the decoupling capacitors needing to be set in the board-level PDN, a designer can conveniently and rapidly determine the decoupling capacitors needing to be set in the board-level PDN and the number of the decoupling capacitors through the method, the efficiency of selecting the decoupling capacitors can be remarkably improved, the design period of the board-level PDN can be shortened, and the design efficiency of the board-level PDN can be improved. And actual application requirements are met.
Description
technical field [0001] The present application relates to the field of computer technologies, and in particular, to a decoupling capacitor selection method, device, server, and readable storage medium. Background technique [0002] With the development of computer technology, the signal rate in the computer system continues to increase, which makes the power integrity problem of the board-level power distribution network (Power Distribution Network, PDN) increasingly prominent. The board-level PDN not only needs to provide a clean and stable power supply voltage for electrical loads, but also plays a role in providing low-noise loops, noise isolation and ensuring electromagnetic integrity for high-speed signals. Therefore, the rationality of board-level PDN design is critical to computer systems. has a significant impact on performance. [0003] In order to reduce the AC impedance of the board-level PDN, thereby reducing the impact of high-speed signals on the power integri...
