Description

Technical Field

[0001] This application relates to the field of computers, and more specifically, to a power supply method and apparatus for a hard disk output extender, a storage medium, and an electronic device. Background Technology

[0002] The hard drive backplane is a crucial component of a server, used to install hard drives, expand their capacity, and improve server performance. Within this backplane, the Expander chip is essential for enabling high-speed hard drive expansion. Therefore, ensuring adequate power supply to the Expander chip on the hard drive backplane is critical.

[0003] In existing technologies, expanders typically require multiple sets of different voltages for power supply, and it is necessary to distinguish between analog circuit power supply and digital circuit power supply. Several voltage regulators (VRs) can be placed on a backplane, allowing direct adjustment of the input voltage on the backplane, thereby simplifying cable design and reducing cable losses. Different expander models have different power supply requirements. In some expander models, analog and digital circuits with the same operating voltage can be powered by the same VR. However, because powering digital circuits requires the use of beads to filter high-frequency noise, the beads generate a voltage drop along the path, which is proportional to the current in the path. This directly affects the voltage supplied to the digital circuits, resulting in errors and lower voltage accuracy. Furthermore, because digital circuits have smaller voltage tolerances, large currents in the path can easily cause the voltage received by the digital circuits to fall below the lower limit of the operating voltage, directly leading to malfunctions of the expander.

[0004] There is still no effective solution to the problem of poor power supply stability in hard drive output expanders in related technologies. Summary of the Invention

The first path parameter is used to indicate the wiring width, wiring area, wiring length and wiring layer number corresponding to the first current path.

[0009] While controlling the voltage applied to the first power supply point to be the working voltage, the second path parameter of the second current path in the candidate power supply circuit is adjusted until the voltage applied to the second power supply point also reaches the working voltage, thereby obtaining the target power supply circuit.

[0022] The operating voltage corresponding to each power supply point is extracted from the operating parameters of the power supply points, and the power supply points with the same operating voltage among all power supply points are identified as the first power supply point and the second power supply point with an association relationship, wherein the operating voltage is the voltage that the power supply point is allowed to load under normal operation.

[0023] Optionally, adjusting the first path parameter of the first current-carrying path until the equivalent path resistance of the first current-carrying path is the minimum resistance value allowed to be reached during the wiring process to obtain a candidate power supply circuit includes:

[0024] During the wiring process of the printed circuit board where the hard disk output expander is located, obtain the maximum wiring width, maximum wiring area, shortest wiring length, and maximum number of wiring layers allowed by the flow path layout.

[0025] Adjust the first path parameters of the first current path to satisfy the maximum wiring width, the maximum wiring area, the shortest wiring length, and the maximum number of wiring layers to obtain a candidate power supply circuit.

[0026] Optionally, the step of adjusting the second path parameter of the second current path in the candidate power supply circuit until the voltage applied to the second power supply point also reaches the operating voltage, while controlling the voltage applied to the first power supply point to be the operating voltage, to obtain the target power supply circuit, includes:

[0027] Adjust the output voltage of the target power supply module to control the voltage applied to the first power supply point to the working voltage;

[0028] The target voltage drop parameter between the target power supply module and the first power supply point is collected, wherein the target voltage drop parameter is used to indicate the voltage difference between the target power supply module and the first power supply point;

[0029] Adjust the second path parameter of the second current path in the candidate power supply circuit until the difference between the voltage drop parameter between the target power supply module and the second power supply point and the target voltage drop parameter is less than the target voltage drop threshold, and obtain the target power supply circuit.

[0030] According to another embodiment of the present application, a power supply device for a hard disk output expander is also provided, comprising:

[0031] A construction module is used to construct an initial power supply circuit, wherein the initial power supply circuit is used to supply power to a first power supply point and a second power supply point that are associated in the hard disk output expander. The first power supply point and the second power supply point have the same operating voltage. The first power supply point is used to supply power to the digital circuits in the hard disk output expander, and the second power supply point is used to supply power to the analog circuits in the hard disk output expander. The initial power supply circuit includes a target power supply module, a first current path, a second current path, and a target noise reduction module. The first current path connects the first power supply point and the target power supply module, the second current path connects the second power supply point and the target power supply module, and the target noise reduction module is deployed on the first current path. The target noise reduction module is used to filter out high-frequency noise in the current path.

[0032] The first adjustment module is used to adjust the first path parameter of the first current path until the equivalent path resistance of the first current path is the minimum resistance value that the current path is allowed to reach during the wiring process, so as to obtain a candidate power supply circuit. The first path parameter is used to indicate the wiring width, wiring area, wiring length and wiring layer number corresponding to the first current path.

[0033] The second adjustment module is used to adjust the second path parameters of the second current path in the candidate power supply circuit while controlling the voltage applied to the first power supply point to be the working voltage, until the voltage applied to the second power supply point also reaches the working voltage, thereby obtaining the target power supply circuit. The second path parameters are used to indicate the wiring width, wiring area, wiring length and wiring layer number corresponding to the second current path.

[0034] According to another aspect of the embodiments of this application, a computer-readable storage medium is also provided, wherein a computer program is stored in the computer program, and the computer program is configured to execute the power supply method of the hard disk output extender described above when it is run.

[0035] According to another aspect of the embodiments of this application, an electronic device is also provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the above-described power supply method for the hard disk output extender through the computer program.

[0036] In this embodiment, an initial power supply circuit is created to power a first power supply point and a second power supply point associated with the hard disk output expander, both of which operate at the same voltage. The first power supply point powers the digital circuitry in the hard disk output expander, while the second power supply point powers the analog circuitry. The initial power supply circuit includes a target power supply module, a first current path, a second current path, and a target noise reduction module. The first current path connects the first power supply point and the target power supply module, and the second current path connects the second power supply point and the target power supply module. The target noise reduction module is located on the first current path and is used to eliminate high-frequency noise in the current path. The first path parameter of the first current path is adjusted until its equivalent path resistance reaches the minimum allowed during routing to obtain a candidate power supply circuit. The first path parameter indicates the wiring width, wiring area, wiring length, and number of wiring layers of the first current path. While controlling the voltage applied to the first power supply point to be the operating voltage, the second path parameter of the second current path in the candidate power supply circuit is adjusted until the voltage applied to the second power supply point also reaches the operating voltage to obtain the target power supply circuit. The second path parameters indicate the wiring width, wiring area, wiring length, and number of wiring layers of the second current path. In other words, after constructing the initial power supply circuit, by adjusting the first path parameters of the first current path, the equivalent path resistance of the first current path is made the minimum resistance allowed during wiring, minimizing the voltage drop on the first current path. This prevents excessive voltage drop from causing the voltage received at the first power supply point on the hard drive output expander to be lower than the operating voltage, thus affecting the normal operation of the hard drive output expander. Simultaneously, for the second current path, adjusting the second path parameters controls the voltage applied to the second power supply point to also reach the operating voltage, ensuring that the voltage received at the second power supply point also conforms to the operating voltage. This technical solution solves the problem of poor power supply stability in hard drive output expanders in related technologies, achieving the technical effect of improving the power supply stability of hard drive output expanders.

[0046] The methods and embodiments provided in this application can be executed on a computer terminal, device terminal, or similar computing device. Taking running on a computer terminal as an example, Figure 1 This is a schematic diagram of the hardware environment for a power supply method for a hard disk output extender according to an embodiment of this application. Figure 1 As shown, a computer terminal may include one or more ( Figure 1Only one is shown in the diagram.

[0049] This embodiment provides a power supply method for a hard disk output extender, applied to the aforementioned computer terminal. Figure 2 This is a flowchart of a power supply method for a hard disk output extender according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps:

[0050] Step S202: Construct an initial power supply circuit, wherein the initial power supply circuit is used to supply power to a first power supply point and a second power supply point that are associated in the hard disk output expander. The first power supply point and the second power supply point have the same operating voltage. The first power supply point is used to supply power to the digital circuits in the hard disk output expander, and the second power supply point is used to supply power to the analog circuits in the hard disk output expander. The initial power supply circuit includes a target power supply module, a first current path, a second current path, and a target noise reduction module. The first current path connects the first power supply point and the target power supply module. The second current path connects the second power supply point and the target power supply module. The target noise reduction module is deployed on the first current path and is used to filter out high-frequency noise in the current path.

[0051] Step S204: Adjust the first path parameter of the first current path until the equivalent path resistance of the first current path is the minimum resistance value that the current path is allowed to reach during the wiring process, and obtain a candidate power supply circuit. The first path parameter is used to indicate the wiring width, wiring area, wiring length and wiring layer number corresponding to the first current path.

[0052] Step S206: While controlling the voltage applied to the first power supply point to be the working voltage, adjust the second path parameter of the second current path in the candidate power supply circuit until the voltage applied to the second power supply point also reaches the working voltage to obtain the target power supply circuit. The second path parameter is used to indicate the wiring width, wiring area, wiring length and wiring layer number corresponding to the second current path.

[0053] Through the above steps, an initial power supply circuit is created to power the associated first and second power supply points in the hard disk output expander. These two power supply points operate at the same voltage. The first power supply point powers the digital circuitry in the hard disk output expander, while the second power supply point powers the analog circuitry. The initial power supply circuit includes a target power supply module, a first current path, a second current path, and a target noise reduction module. The first current path connects the first power supply point and the target power supply module, and the second current path connects the second power supply point and the target power supply module. The target noise reduction module is located on the first current path and is used to eliminate high-frequency noise in this current path. The first path parameter of the first current path is adjusted until its equivalent path resistance reaches the minimum allowed during routing to obtain a candidate power supply circuit. The first path parameter indicates the wiring width, wiring area, wiring length, and number of wiring layers of the first current path. While controlling the voltage applied to the first power supply point to be the operating voltage, the second path parameter of the second current path in the candidate power supply circuit is adjusted until the voltage applied to the second power supply point also reaches the operating voltage to obtain the target power supply circuit. The second path parameters indicate the wiring width, wiring area, wiring length, and number of wiring layers of the second current path. In other words, after constructing the initial power supply circuit, by adjusting the first path parameters of the first current path, the equivalent path resistance of the first current path is made the minimum resistance allowed during wiring, minimizing the voltage drop on the first current path. This prevents excessive voltage drop from causing the voltage received at the first power supply point on the hard drive output expander to be lower than the operating voltage, thus affecting the normal operation of the hard drive output expander. Simultaneously, for the second current path, adjusting the second path parameters controls the voltage applied to the second power supply point to also reach the operating voltage, ensuring that the voltage received at the second power supply point also conforms to the operating voltage. This technical solution solves the problem of poor power supply stability in hard drive output expanders in related technologies, achieving the technical effect of improving the power supply stability of hard drive output expanders.

[0054] In the technical solution provided in step S202 above, Figure 3 This is a schematic diagram of an initial power supply circuit according to an embodiment of this application, such as... Figure 3As shown, the hard drive output expander, target power supply module, and target noise reduction module can, but are not limited to, all be deployed on the hard drive backplane and connected via copper current paths. These current paths include a first current path and a second current path. The hard drive backplane is a physical structure installed in a server or storage system to support multiple hard drives. The expander chip is an integrated circuit chip within the backplane, its function being to expand the backplane's storage capacity. The expander chip in the hard drive backplane can expand a single SAS (Serial Attached Storage) port into multiple SAS ports, allowing a single SAS controller to connect more hard drives. By assigning SAS addresses, the expander chip can identify and manage all hard drives connected to the expander. In a storage system, the expander chip can combine multiple physical hard drives into a logical volume, providing greater storage capacity. The hard drive backplane and its expander chip are both crucial components of a storage system; they support and manage hard drives, providing greater storage capacity and higher performance. Therefore, a stable power supply to the expander is essential for the normal operation of the hard drive backplane.

[0055] Optionally, in this embodiment, such as Figure 3 As shown, the hard disk output expander includes a first power supply point (VDDA) and a second power supply point (VDD). The hard disk output expander internally includes digital circuits and analog circuits. The analog circuit power supply and digital circuit power supply are usually provided separately. The first power supply point (VDDA) is used to power the digital circuits and can be, but is not limited to, the power supply voltage pin of the digital circuits, used to receive the voltage provided by the power supply party. The second power supply point (VDD) is used to power the analog circuits and can be, but is not limited to, the power supply voltage pin of the analog circuits, used to receive the voltage provided by the power supply party.

[0056] Optionally, in this embodiment, such as Figure 3As shown, the target power supply module (VR1) can be, but is not limited to, a voltage regulator in the Expander chip. It is a circuit module mainly used to adjust the operating voltage of the internal circuit of the chip to ensure the normal operation of each module inside the chip. The voltage value of FB (voltage feedback) can be controlled by changing the regulating resistors RH and RL corresponding to the target power supply module. The voltage of FB is equal to that of VDD_L. VDD_L is the output voltage of the target power supply module, which is used to supply power to the connected first power supply point (VDDA) and second power supply point (VDD). The first power supply point is connected to the target power supply module through a first current path, and the second power supply point is connected to the target power supply module through a second current path. Since there is a line resistance in the first current path (corresponding to R2) and a line resistance in the second current path (corresponding to R1), and the target noise reduction module (Bead 1, ferrite bead) is also deployed on the first current path, the target noise reduction module also has a resistance. Therefore, VDD_L will cause a voltage drop when transmitted to the first power supply point due to the target noise reduction module and R2, and VDD_L will cause a voltage drop when transmitted to the second power supply point due to R1.

[0057] Optionally, in this embodiment, such as Figure 3 As shown, the target noise reduction module (Bead 1, ferrite bead) can be used to filter high-frequency noise. The reason why the digital power supply section of the Expander chip can use a Bead to filter high-frequency noise is to prevent high-frequency noise from interfering with and damaging the digital circuits. Components in digital circuits are usually very sensitive; they are highly sensitive to fluctuations in supply voltage and noise. Once interfered with by high-frequency noise, circuit failures or data errors may occur. Especially in high-speed digital signal systems, the impact of high-frequency noise on signal quality and system performance is more significant. A Bead is an electronic component with a structure similar to an inductor, which can filter high-frequency noise and maintain the transmission of low-frequency signals. In the Expander chip, the digital power supply section typically uses Beads to filter high-frequency noise to ensure the stability and interference suppression capability of the digital circuits. Specifically, Beads can filter high-frequency noise signals through their high impedance characteristics and provide clean power signals to the digital circuits, thereby reducing the impact of high-frequency noise on the digital circuits. In summary, using Beads to filter high-frequency noise in the digital power supply section of the Expander chip can improve the reliability and stability of the chip and prevent high-frequency noise from interfering with and damaging the digital circuits.

[0058] Optionally, in this embodiment, the tolerances of the first power supply point (VDDA) and the second power supply point (VDD) are relatively small, typically ±1%. In the Expander chip, a Bead (corresponding to the aforementioned target noise reduction module, a ferrite bead) is used to filter out high-frequency noise in the VDDA power path. However, when high-frequency noise passes through the Bead, it generates a voltage drop, and this voltage drop is proportional to the current. Since the current in the VDDA power path can vary during chip operation, the voltage drop generated by the Bead will also vary with the current. This means that under high current, the VDDA voltage at the Expander may fall below the lower limit of the operating voltage. This situation may affect the normal operation of the Expander, as the Expander requires a stable power supply voltage to ensure its normal operation. If the VDDA voltage falls below the lower limit of the operating voltage, the chip may experience errors, malfunctions, or data errors, which will affect the chip's performance and reliability.

[0059] Optionally, in this embodiment, the first power supply point (VDDA) and the second power supply point (VDD) may, but are not limited to, the two types of power supply voltage pins indicating the two expanders, the difference being that the circuit types they power are different (analog circuits and digital circuits). There is no limitation to only one first power supply point (VDDA) and one second power supply point (VDD). When an expander includes multiple first power supply points or multiple second power supply points, multiple first power supply points and multiple second power supply points with the same operating voltage can all be used with the power supply method of the hard disk output expander proposed in this application.

[0060] In one exemplary embodiment, the initial power supply circuit may be constructed, but is not limited to, by: identifying the first power supply point and the second power supply point that are associated from all power supply points included in the hard disk output extender; selecting a power supply module that matches the power supply requirements of both the first power supply point and the second power supply point as the target power supply module, and selecting a noise reduction module that matches the noise reduction requirements of the first power supply point as the target noise reduction module; connecting the second power supply point and the target power supply module through the second flow path, and simultaneously connecting the first power supply point and the target power supply module through the first flow path, and deploying the target noise reduction module between the first power supply point and the target power supply module to obtain the initial power supply circuit.

[0061] Optionally, in this embodiment, both the first and second power supply points have power supply requirements, including voltage and current requirements. The target power supply module can simultaneously meet the power supply requirements of both the first and second power supply points. In addition, the first power supply point, unlike the second, also has a noise reduction requirement. This is because the first power supply point is the power supply voltage pin for the digital circuit. Components in digital circuits are typically very sensitive, highly susceptible to fluctuations in power supply voltage and noise. Interference from high-frequency noise can lead to circuit failures or data errors. Especially in high-speed digital signal systems, the impact of high-frequency noise on signal quality and system performance is more significant. Therefore, noise reduction is performed before applying voltage to the first power supply point. The high impedance characteristics of the target noise reduction module filter out high-frequency noise signals, providing a clean power signal to the digital circuit, thereby reducing the impact of high-frequency noise on the digital circuit.

[0062] In one exemplary embodiment, a power supply module that matches the power supply requirements of both the first power supply point and the second power supply point may be selected as the target power supply module in the following manner, but not limited to: obtaining the voltage requirement parameter and current requirement parameter of each power supply point in the first power supply point and the second power supply point, wherein the voltage requirement parameter is used to indicate the voltage value required by each power supply point under normal power supply conditions, and the current requirement parameter is used to indicate the maximum current value allowed to pass through each power supply point; selecting a power supply module that matches both the voltage requirement parameter and the current requirement parameter as the target power supply module, wherein when the first power supply point and the second power supply point are simultaneously connected to the target power supply module, the voltage loaded on each power supply point satisfies the corresponding voltage requirement parameter, and the current passing through each power supply point satisfies the corresponding current requirement parameter.

[0063] Optionally, in this embodiment, for each power supply point, there are voltage requirement parameters and current requirement parameters. The voltage requirement parameter can indicate the voltage value required by the power supply point under normal power supply conditions, and the current requirement parameter can indicate the maximum current value allowed to pass through the power supply point. The target power supply module needs to meet the following requirements: when the first power supply point and the second power supply point are connected at the same time, the voltage of each power supply point meets the corresponding voltage requirement parameter, and the current passing through each power supply point meets the corresponding current requirement parameter.

[0064] In one exemplary embodiment, a noise reduction module matching the noise reduction requirements of the first power supply point may be selected as the target noise reduction module by, but not limited to, the following methods: obtaining noise reduction requirement parameters of the first power supply point, wherein the noise reduction requirement parameters are used to indicate the maximum noise intensity of high-frequency noise that the first power supply point is allowed to receive; selecting the noise reduction module that satisfies the noise reduction requirement parameters as the target noise reduction module; or, selecting the noise reduction module with the smallest module resistance value from a plurality of noise reduction modules that satisfy the noise reduction requirement parameters as the target noise reduction module.

[0065] Optionally, in this embodiment, the noise reduction requirement parameter is used to indicate the maximum noise intensity of high-frequency noise that the first power supply point is allowed to receive, and the target noise reduction module needs to control the noise intensity of high-frequency noise in the deployment path below the maximum noise intensity.

[0066] Optionally, in this embodiment, when there are multiple noise reduction modules that meet the noise reduction requirements, the noise reduction module with the smallest resistance can be selected from the multiple noise reduction modules as the target noise reduction module to further reduce the resistance in the current path and avoid additional voltage drop and power loss.

[0067] In one exemplary embodiment, the first power supply point and the second power supply point with an association can be identified from all power supply points included in the hard disk output expander by, but not limited to, the following: detecting the site operating parameters of each power supply point among all the power supply points included in the hard disk output expander, wherein the site operating parameters are used to indicate the power parameters that each power supply point is allowed to load under normal operation; extracting the operating voltage corresponding to each power supply point from the site operating parameters, and determining the power supply points with the same operating voltage among all power supply points as the first power supply point and the second power supply point with an association, wherein the operating voltage is the voltage that the power supply point is allowed to load under normal operation.

[0068] Optionally, in this embodiment, the first power supply point and the second power supply point that are associated have the same operating voltage. There may be multiple power supply points on the hard disk output expander. The first power supply point and the second power supply point that have the same operating voltage can be powered by the same target power supply module.

[0069] In the technical solution provided in step S204 above, the first current path can be a copper line used to conduct power between the target power supply module and the first power supply point. Since the first current path itself has a path resistance, the voltage output by the target power supply module will be lost in the first current path. Therefore, when routing on the PCB (Printed Circuit Board), if the board size or routing specifications allow, appropriate first path parameters should be selected until the equivalent path resistance of the first current path is the minimum resistance that the current path can reach during the routing process, thereby reducing the voltage drop caused by the path resistance of the first current path itself.

[0070] In an exemplary embodiment, the first path parameter of the first current path can be adjusted, but is not limited to, in the following manner, until the equivalent path resistance of the first current path is the minimum resistance value allowed to be reached by the current path during the wiring process, to obtain a candidate power supply circuit: obtaining the maximum wiring width, maximum wiring area, shortest wiring length, and maximum number of wiring layers allowed by the current path of the printed circuit board where the hard disk output expander is located during the wiring process; adjusting the first path parameter of the first current path to satisfy the maximum wiring width, the maximum wiring area, the shortest wiring length, and the maximum number of wiring layers to obtain a candidate power supply circuit.

[0071] Optionally, in this embodiment, when the first path parameters of the first current path satisfy the maximum wiring width, maximum wiring area, minimum wiring length and maximum number of wiring layers, the path resistance value of the first current path is the minimum resistance value that the current path is allowed to reach during the wiring process.

[0072] In the technical solution provided in step S206 above, since the first current path has an additional target noise reduction module compared to the second current path, the second path parameters of the second current path can be adjusted until the sum of the equivalent resistance of the first current path and the resistance of the target noise reduction module is close to the equivalent resistance of the second current path. Therefore, the copper pour of the second current path should not be too wide while meeting the maximum current requirement, so as to ensure that there is redundancy in the adjustment value of the output voltage of the target power supply module.

[0073] In one exemplary embodiment, the target power supply circuit can be obtained by adjusting the second path parameter of the second current path in the candidate power supply circuit, while controlling the voltage applied to the first power supply point to be the operating voltage, until the voltage applied to the second power supply point also reaches the operating voltage, in the following manner: adjusting the output voltage of the target power supply module to control the voltage applied to the first power supply point to be the operating voltage; acquiring a target voltage drop parameter between the target power supply module and the first power supply point, wherein the target voltage drop parameter is used to indicate the voltage difference between the target power supply module and the first power supply point; adjusting the second path parameter of the second current path in the candidate power supply circuit until the difference between the voltage drop parameter between the target power supply module and the second power supply point and the target voltage drop parameter is less than a target voltage drop threshold, thereby obtaining the target power supply circuit.

[0074] Optionally, in this embodiment, the second path parameter of the second current path in the candidate power supply circuit can be adjusted by using software to perform PI simulation. Based on the simulation results of the first power supply point VDDA, the copper pour width of VDD is adjusted so that the voltage drop on the VDD current path is close to the voltage drop on the VDDA current path (including the voltage drop on the Bead).

[0075] To better understand the power supply process of the aforementioned hard disk output expander, the power supply process of the aforementioned hard disk output expander will be described below in conjunction with optional embodiments, but this is not intended to limit the technical solutions of the embodiments of this application.

[0076] This embodiment provides a power supply method for a hard disk output extender. Figure 4 This is a schematic diagram of the power supply process of a hard disk output extender according to an embodiment of this application, such as... Figure 4 As shown, the main steps include the following:

[0077] Step S401: Design a suitable VR based on the maximum operating currents of VDD and VDDA, and connect the VR's detection point to VDD at the Expander.

[0078] Step S402: Based on the high-frequency filtering effect and DC resistance, select a suitable Bead and place it close to VR;

[0079] Step S403: When routing on the PCB, the copper pour for VDDA should be as wide as possible to reduce the impedance on the current path; the copper pour for VDD should not be too wide while meeting the maximum current requirement.

[0080] Step S404: Use software to perform simulation. Based on the VDDA simulation results, adjust the copper pour width of VDD so that the voltage drop on the VDD current path is close to the voltage drop on the VDDA current path (including the voltage drop on the Bead).

[0081] In this configuration, a single VR is used to simultaneously power both VDD and VDDA of the Expander, with the Bead placed close to the VR. Assume the currents of VDD and VDDA are ID and ID, respectively. O1 I O2 Assume that the equivalent resistances of the current paths of VDD and VDDA on the board are R1 and R2, respectively, and their resistance values ​​are related to the copper layer length, area, and number of layers of the current path.

[0082] First, VR detects the voltage of VDD at the Expander and ensures that the VDD voltage at the Expander is stable at the set value. Then, VDD_L = VDD + R1 × I O1 The voltage at Expander, VDDA, is: VDDA = VDD_L - (R Bead +R2)×I O2 =VDD+R1×I O1 -(R Bead +R2)×I O2 ;

[0083] Secondly, during PCB routing, by adjusting the width of the VDD and VDDA current paths and combining this with software simulation, the R1×I value is optimized. O1 Approaching (R) Bead +R2)×I O2 Then VDDA will be close to VDD, which meets the operating voltage requirements of Expander.

[0084] It should be noted that the power supply mechanism of the hard disk output expander proposed in this application, in addition to the VDDA power supply of Expander, can also be applied to other scenarios where the device uses a bead and the current is large.

[0085] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods of the various embodiments of this application.

[0086] Figure 5 This is a structural block diagram of a power supply device for a hard disk output expander according to an embodiment of this application; as shown... Figure 5 As shown, it includes:

[0087] A construction module 502 is used to construct an initial power supply circuit, wherein the initial power supply circuit is used to supply power to a first power supply point and a second power supply point that are associated in the hard disk output expander. The first power supply point and the second power supply point have the same operating voltage. The first power supply point is used to supply power to the digital circuits in the hard disk output expander, and the second power supply point is used to supply power to the analog circuits in the hard disk output expander. The initial power supply circuit includes a target power supply module, a first current path, a second current path, and a target noise reduction module. The first current path connects the first power supply point and the target power supply module, and the second current path connects the second power supply point and the target power supply module. The target noise reduction module is deployed on the first current path and is used to filter out high-frequency noise in the current path.

[0088] The first adjustment module 504 is used to adjust the first path parameter of the first current path until the equivalent path resistance of the first current path is the minimum resistance value that the current path is allowed to reach during the wiring process, so as to obtain a candidate power supply circuit. The first path parameter is used to indicate the wiring width, wiring area, wiring length and wiring layer number corresponding to the first current path.

[0089] The second adjustment module 506 is used to adjust the second path parameters of the second current path in the candidate power supply circuit when the voltage applied to the first power supply point is the working voltage, until the voltage applied to the second power supply point also reaches the working voltage, thereby obtaining the target power supply circuit. The second path parameters are used to indicate the wiring width, wiring area, wiring length and wiring layer number corresponding to the second current path.

[0090] It should be noted that the above modules can be implemented by software or hardware. For the latter, they can be implemented in the following ways, but are not limited to: all the above modules are located in the same processor; or, the above modules are located in different processors in any combination.

[0091] Through the above embodiments, an initial power supply circuit is created to power a first power supply point and a second power supply point associated with each other in the hard disk output expander. These two power supply points operate at the same voltage. The first power supply point powers the digital circuitry in the hard disk output expander, while the second power supply point powers the analog circuitry. The initial power supply circuit includes a target power supply module, a first current path, a second current path, and a target noise reduction module. The first current path connects the first power supply point and the target power supply module, and the second current path connects the second power supply point and the target power supply module. The target noise reduction module is located on the first current path and is used to eliminate high-frequency noise in this current path. The first path parameter of the first current path is adjusted until its equivalent path resistance reaches the minimum allowed during routing to obtain a candidate power supply circuit. The first path parameter indicates the routing width, routing area, routing length, and number of routing layers of the first current path. While controlling the voltage applied to the first power supply point to be the operating voltage, the second path parameter of the second current path in the candidate power supply circuit is adjusted until the voltage applied to the second power supply point also reaches the operating voltage to obtain the target power supply circuit. The second path parameters indicate the wiring width, wiring area, wiring length, and number of wiring layers of the second current path. In other words, after constructing the initial power supply circuit, by adjusting the first path parameters of the first current path, the equivalent path resistance of the first current path is made the minimum resistance allowed during wiring, minimizing the voltage drop on the first current path. This prevents excessive voltage drop from causing the voltage received at the first power supply point on the hard drive output expander to be lower than the operating voltage, thus affecting the normal operation of the hard drive output expander. Simultaneously, for the second current path, adjusting the second path parameters controls the voltage applied to the second power supply point to also reach the operating voltage, ensuring that the voltage received at the second power supply point also conforms to the operating voltage. This technical solution solves the problem of poor power supply stability in hard drive output expanders in related technologies, achieving the technical effect of improving the power supply stability of hard drive output expanders.
