[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0029] Example 1: Figure 1 and Figure 2 A flowchart illustrating the method for calculating the DC resistance of copper foil provided in an embodiment of the present invention. Figure 1 and Figure 2 As shown, the method includes: S101. Set port data.

[0030] In this step, the port data setting includes at least one of the following: 1) In response to the user's selection of a specific network, identify all relevant device pins under the specific network as candidate ports and set them as ports in batches after prompting the user for confirmation; or in response to the user's selection of a specific network, set all relevant device pins under the specific network as ports.

[0031] 2) In response to the user's selection operation of target pins on the layout, add the target pins selected by the user as ports.

[0032] 3) Directly convert user-preset power supplies and loads to ports.

[0033] As an optional implementation method, such as Figure 4 As shown, there are three ways to configure the port: The first method integrates a network filter into the settings interface. By selecting a target network, the interface automatically lists all the pins of the devices contained in that network, which can be set as ports with one click, making the operation quick and easy.

[0034] The second method allows users to directly select pins and add ports in the layout, achieving precise position-level positioning, which is intuitive and efficient.

[0035] The third approach addresses the key attributes of power supplies and loads by providing a one-click "Power Supply / Load → Port" conversion function, allowing users to directly incorporate defined power supplies or loads into subsequent simulation port sets without repeated configuration.

[0036] Regarding the first method, a network filtering function is provided in the settings interface. Users can use this function to select a specific network. After switching networks, the pins of all relevant devices in that network will be automatically displayed in the interface, allowing users to set these pins as ports. Essentially, users can use the network filtering function to select one of several pre-configured networks as the target network. Regarding the third method, considering the special role of power supplies and loads in the circuit, a function is provided to directly convert pre-configured power supplies and loads into ports. Users can easily use these key components as ports in subsequent simulations. The selection operation can be performed by mouse clicks or touchscreen clicks; no specific method is required here.

[0037] In one possible implementation, in the second approach, when the user hovers over a candidate pin on the layout, the outline of the component to which the candidate pin belongs is displayed on the layout, and the network connection relationship of the candidate pin after being incorporated into the port set is shown on a display window. The display window is presented as an independent window relative to the layout, used to display the network connection relationship of the candidate pin in the port set after it has been set as a port, and to simplify the connection diagram, retaining only the port-to-port connections.

[0038] In some embodiments, setting the port data includes: S1011. Select a target network using the network filtering function, and initialize all device pins that conform to electrical rules under the target network as the first port set.

[0039] S1012. Present the first port set in the layout and receive user interaction operations to form a second port set, wherein the interaction operations include adding new pins as ports or deleting redundant ports on the layout.

[0040] S1013. Automatically scan the layout and identify components of a preset type; then, determine whether the second port set does not contain the identified components: if not, prompt the user whether to convert the identified components into ports; after receiving the user's confirmation instruction for conversion, merge the newly generated ports into the second port set to form a third port set.

[0041] This step is followed by: like Figure 5 As shown, port data is validated to check whether the data is invalid. The validation includes enable validation and valid bit validation. The enable validation is used to determine whether the port corresponding to the port data has been enabled. If the port is not enabled, the port data is determined to be invalid. The valid bit validation is used to determine whether the feature bits in the port data meet the preset valid conditions. If the feature bits do not meet the conditions, the port data is determined to be invalid.

[0042] The above enable verification is as follows: read the enable bit field in the port data. If the value of the field is logic 0 or the enumerated value Disabled, it is determined that the port is in an enabled state and the corresponding port data is invalid; otherwise, if the enable bit is logic 1 or the enumerated value Enabled, it is determined that the port is enabled and the verification passes.

[0043] The above valid bit verification is as follows: read the valid bit field in the port data and perform a bitwise AND operation with the preset mask. If the result is not equal to the expected mask value, or if any feature bit has an illegal combination (such as a non-zero reserved bit or a checksum error), the feature bit is determined to not meet the valid condition and the port data is invalid. If the result is completely consistent with the mask and the checksum is correct, the valid condition is determined to be met and the verification passes.

[0044] If the verification passes, proceed to step S102.

[0045] S102. Write the port data into a configuration file, which is used for mesh generation and solver invocation.

[0046] In this step, such as Figure 5 As shown, during simulation, setting data is written to a settings file to ensure traceability. When users need to share settings, they can directly read this file without repeating manual configuration. Furthermore, pin data is also written to files required for mesh generation and finite element calculations.

[0047] S103. Based on the settings file, a simulation result file is obtained, which includes the DC resistance result data of the copper foil.

[0048] In this step, such as Figure 6 As shown, after writing the port settings file, the mesh generation module and solver are automatically invoked. The mesh generation module discretizes the geometric model into triangular elements for finite element analysis. The solver calculates the voltage and current distribution (calculates the voltage and current parameters at each point in the circuit) based on the physical model and boundary conditions, thereby obtaining the DC resistance of the copper foil.

[0049] S104. Parse the result file to obtain the resistance information between the ports.

[0050] In this step, such as Figure 7 As shown, the result file generated by the solver is analyzed to extract the relationships between terminals and the simulation result data. By parsing the result file, the resistance information between each port can be obtained (this information is very important for evaluating the performance and reliability of the circuit) and saved to the graphical display interface.

[0051] In some embodiments, such as Figure 8 As shown, parsing the result file to obtain the resistance information between ports includes: S1041. Use the result file parsing to obtain the network connection relationship and the DC resistance value of the copper area, and generate the resistance information between ports.

[0052] S1042. Write the resistance information into the display interface association model to associate the display window and layout.

[0053] S1043. Establishing the association between the display window and the layout: When a port-port resistance record is selected in the display window, the corresponding port pair is simultaneously highlighted in the layout; and / or when a port is selected or the currently selected port is displayed in the layout, the display window is simultaneously positioned to the resistance record list of that port and the corresponding other ports, such as... Figure 10 As shown.

[0054] In S1044, another display window is also configured; after the user clicks on the port-port resistance record of the display window, the other window displays all the pins included in each of the two ports.

[0055] It is worth noting that the simulation results obtained from the analysis are displayed in an intuitive way in the user interface. In addition to the usual data display, it also emphasizes the relationships between different ports, the relationships between ports and the pins that make up the ports in the layout interface, and the display of the currently selected port in the layout. This helps users quickly understand the detailed information of the ports of interest, facilitating result analysis and verification.

[0056] In some embodiments, such as Figure 11 As shown, the display form is also used to set the ports that need to be simulated. Double-clicking a port in the list will take the user to the corresponding pin location on the layout.

[0057] In some embodiments, after the simulation yields a result file, the method further includes: exporting the relationships and values ​​between ports in the result file to a table document, wherein the table document includes port, pin and layer information and result data.

[0058] like Figure 3 and Figure 9 As shown, an export button is provided in the display window, and the export button is associated with export code. In response to the user clicking the export button, the export code retrieves the relationships between ports and their corresponding values ​​in the result file. The export code writes the data into a table document in Excel or CSV format, and the table document includes port information, pin information, layer information, and the relationship data between ports.

[0059] It is worth noting that this embodiment provides an export function, which exports the relationships and values ​​between ports in the results to an Excel or CSV document for report writing or subsequent data analysis. The exported content includes port information, pin and layer information, and result data, ensuring that users can completely record and share the simulation process and results.

[0060] Example 2: Figure 11 This is a structural diagram of the copper-plated DC resistance calculation device provided in an embodiment of the present invention. Figure 11 As shown, the device includes: Module 1201 is used to configure port data.

[0061] The writing module 1202 is used to write the port data into a configuration file, which is used for mesh generation and solver invocation.

[0062] The simulation module 1203 is used to simulate and obtain a result file based on the setting file, the result file including the DC resistance result data of the copper foil.

[0063] The parsing module 1204 is used to parse the result file to obtain the resistance information between ports.

[0064] In one embodiment, setting the port data includes at least one of the following: in response to a user's selection of a specific network, identifying all relevant device pins under the specific network as candidate ports and prompting the user for confirmation before setting them as ports in batches; or in response to a user's selection of a specific network, setting all relevant device pins under the specific network as ports; in response to a user's selection of target pins on the layout, adding several target pins selected by the user as ports; or directly converting user-preset power supplies and loads into ports.

[0065] In one embodiment, setting the port data includes: selecting a target network through a network filtering function, initializing all device pins conforming to electrical rules under the target network as a first port set; displaying the first port set in the layout and receiving user interaction operations to form a second port set, wherein the interaction operations include adding new pins as ports or deleting redundant ports on the layout; automatically scanning the layout to identify components of a preset type; then determining whether the second port set does not contain the identified components: if not, prompting the user whether to convert the identified components into ports; and after receiving the user's confirmation of the conversion, merging the newly generated ports into the second port set to form a third port set.

[0066] In one embodiment, after the simulation yields a result file, the method further includes: exporting the relationships and values ​​between the ports in the result file to a table document, wherein the table document includes port, pin and layer information and result data.

[0067] In one embodiment, before writing the port data into the configuration file, the method further includes: verifying the port data to check whether the data is invalid. The verification includes enable verification and valid bit verification. The enable verification is used to determine whether the port corresponding to the port data has been enabled. If the port is not enabled, the port data is determined to be invalid. The valid bit verification is used to determine whether the feature bits in the port data meet the preset valid conditions. If the feature bits do not meet the conditions, the port data is determined to be invalid.

[0068] In one embodiment, parsing the result file to obtain the resistance information between ports includes: using the result file to parse and obtain the network connection relationship and the DC resistance value of the copper area, generating the resistance information between ports; writing the resistance information into the display interface association model to associate the display window and the layout; constructing the association action between the display window and the layout: when a port-port resistance record is selected in the display window, the corresponding port pair is simultaneously highlighted in the layout; and / or when a port is selected in the layout or the currently selected port is displayed, the display window is simultaneously positioned to the resistance record list of that port and the corresponding other ports.
