In the accompanying drawings, several embodiments of the present disclosure are shown in an exemplary and non-limiting manner, in which: In the drawings, the same or corresponding reference numerals represent the same or corresponding parts.

DETAILED DESCRIPTION

[0021] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0022] In the related art, the design library of electronic components is not centrally managed, resulting in the following problems.

[0023] 1. Single-soldier operation: Schematic symbols commonly used in hardware development, printed circuit board (PCB) packaging, device manuals, and related material information are managed separately, and each engineer has a pile of data in his hands, which is scattered and messy.

[0024] 2. Some companies can use Excel to manage materials and schematic symbol libraries, PCB package libraries and the subordinate relationships between them, but this type of management is not secure enough, lacks permission management, and lacks duplicate checking mechanisms, and there are still many hidden dangers.

[0025] 3. Better companies use Enterprise Resource Planning (EPR) and Product Lifecycle Management (PLM) methods to manage materials, but these methods are separated from electronic design automation (EDA) tools. Method information cannot be delivered to hardware engineers in a timely manner. Designers need to use multiple methods to search for information, which is very inefficient.

[0026] 4. Finally, the way of building libraries, such as symbol libraries, PCB package libraries, and 3D models, is still the traditional manual library building, which is very inefficient.

[0027] The above reasons lead to decentralized material warehouse management and waste of resources.

[0028] The material library management method and device provided by the present application are introduced below in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, the material library management method provided by this application includes: S101, creating a device library, and configuring functional modules and general attributes in the device library; the functional modules are provided with functions for processing devices; the general attributes include power consumption parameters, power supply parameters, heat dissipation requirements, 3D models, cost factors, rule constraints, key performance and reliability data; The EDA design resource library management method in this application is applied to Figure 2The device library management system in . Among them, the functional modules include electronic design tools, unit circuit management modules, data management modules, material management modules and basic model libraries. Among them, the electronic design tools include model calling interface, design rule check (DRC) verification interface, automatic archiving interface, etc. The unit circuit management module is used for standard circuit model management, including unit circuit parameterization, unit circuit visualization, electronic design automation (EDA) calling interface block diagram design, circuit comparison and derivation, and compatible formats of multiple EDA formats; the data management module can call the model, intelligently search, compare, call the data, visualize the model and derivation management, etc.; the material management module mainly manages the electrical, including basic data supply information, electrical parameter reliability parameters, artificial intelligence AI modeling, document / case design specifications, etc.; the basic model library includes a variety of available models, such as large prediction models, deep learning models, etc.

[0030] S102, receiving a first target instruction, determining a corresponding search method based on the first target instruction, and searching the device library for a functional module corresponding to the first target instruction according to the search method; In the present application, the user can input the first target instruction in two ways, namely, through the Web or the desktop. The present application can determine the corresponding search method according to the first target instruction, thereby searching for the corresponding functional module in the device library.

[0031] In some embodiments, when the target component is a target device, determining the corresponding search method based on the first target instruction includes: Determine basic parameters and characteristic parameters of the device to be searched according to the first target instruction; Determine a search method according to the basic parameters and characteristic parameters; The basic parameters include manufacturer, product production status, value and tolerance range; the characteristic parameters include the number of references of circuit components and device designs; When the target component is a target circuit, determining a corresponding search method based on the first target instruction includes: Determine a target circuit code, name, abbreviation or chip code based on the first target instruction; Search based on the target circuit code, name, abbreviation or chip code.

[0032] It is understandable that in this application, if the target component is a target device, the device list provides a specific search interface under a specific device classification, and different search methods can be provided according to various basic attributes and characteristic attributes of the device. The conditions include: manufacturer, product production status, value, tolerance range, number of references to circuit components and designs, etc. The content of the search box can be selected from the list or entered manually. The search results can be filtered step by step in the order entered by the user until the target device is found. The search results are displayed below the search box in the search interface. If the target component is a target circuit, the module circuit is retrieved by searching the circuit code, name, abbreviation, or searching the code of the key chip, or the department to which it belongs.

[0033] In some embodiments, it also includes: When multiple components are searched out, the multiple components are compared to determine the differences between the multiple components; A second target instruction is received, and a target component matching the second target instruction is determined based on the second target instruction and the difference.

[0034] It is understandable that in this application, multiple matching devices are searched by parameters, multiple devices are compared in parameters, and the differences are listed and distinguished by colors. Similarly, circuit components can also be compared, and the comparison content includes adding / deleting modules, changing connection relationships, adding / deleting devices, checking the integrity of the connection, checking the port standardization, and checking the standardization of devices.

[0035] S103, using the searched functional module to process the target component corresponding to the first target instruction, and visualize the processing result; wherein the target component includes a target device and a target circuit.

[0036] In some embodiments, the processing of the target component corresponding to the first target instruction includes at least one of the following: View the usage count, reference number, project or component version of the target component; Calling a device model corresponding to the target component in a device library; Check whether the target component is a standard component and the status of the target component, and if the target component is a non-standard component or the target component is in a disabled state, issue an alarm; Compare and inspect the target circuit where the target component is located with the standard circuit according to preset inspection rules, mark the changed parts of the target circuit from the standard circuit; and modify the target circuit; Determine the validity of materials corresponding to the target component in the device library, and delete or replace invalid materials therein; View the references, historical versions, parameters, documents, and derived solutions of the target component.

[0037] The device library provided in this application can also visualize device models, such as viewing device supply information, electrical parameters, detailed documentation, and model previews.

[0038] Specifically, in this application, the device library is used to check which circuits or circuit components the device is referenced by, and to check the number of times the device is used, the bit number, the project or circuit component version, etc. When checking in the bill of material (BOM), the device data is parsed and stored for reference in device selection. Specifically, you can view the device reference details, application circuit name, application circuit number, reference quantity, and reference version. Similarly, the circuit component reference status can be viewed through the device library, and the detailed parameters, detailed documents, BOM, material cost (BOM export Excel to view the cost) of the circuit component can be viewed. The material cost of the circuit component can also be displayed in the basic attribute column as needed. When CBB submits the EDM system, the detailed data of CBB is uploaded in a structured storage to facilitate the subsequent maintenance of CBB circuit usage statistics and tracing.

[0039] It is also possible to call device models, for example, you can directly query the placement model through the Place part or Design Entry HDL library interface. Call the device model to Design Entry HDL. This application can check whether the device is a standard device or a standard module in the Capture / HDL / AD environment. Whether the device is in a disabled state, and an alarm will be issued if it violates the rules. The device library of this application can also perform a comparative check on the standard circuit. When the following changes are detected, the system will give an alarm reminder and highlight the corresponding position of the drawing. The following differences can be identified and located. For example, add / delete modules, add / delete devices, change connection relationships, check wiring integrity, and check port standardization. It is also possible to check the standardization of devices: the coding and model inconsistencies between the device and the circuit components of the standard library. The device library also supports batch review of drawings, obtains all design drawings with invalid materials from the drawing system, batch replaces disabled materials, and can help designers batch refresh missing attributes in the design. The device library also supports batch import of existing circuit components and adds, deletes, and modifies models according to the process to achieve full life cycle maintenance of circuit component models. EDM supports the process of adding / modifying circuit components. EDA uploads the relevant materials of the circuit components, EDM receives the circuit component materials to complete the review process, and publishes them. The circuit component library files enter the server, and the EDM circuit component data is published, and EDA can query and call them.

[0040] The device library provided by this application supports batch import of existing models, as well as adding, deleting and modifying models according to the process, and realizing full life cycle maintenance of device models and CBB models. It can also be integrated with the PLM system. When devices are added and changed in the PLM system, the new devices automatically transfer relevant properties and files through the interface, and are imported from PLM to EDM. Device attribute changes are synchronized, and attribute changes, prices, delivery dates, inventory, whether disabled, etc. are synchronized with ERP. PLM provides device classification information and related attributes, http interface or shared database. Push device parameters to Capture / HDL / AD from the EDM model management system or integrated library end for EDA tools to call Symbol symbols and packaging information.

[0041] This application supports batch import, centralized storage, addition, deletion, modification, classification management, full life cycle maintenance, and permission management of models. When the device change does not affect the model change, the administrator can implement full life cycle maintenance through the enable and disable switch buttons on the interface. When the device change causes the model to change, the full life cycle maintenance of the model is implemented through a complete approval process.

[0042] This application can also mark disabled devices with a disabled mark, and at the same time, the system restricts them from entering the integrated library or clicking on Place part / Place circuit components, prompting that the device or circuit component is in a disabled state. Corresponding permissions are assigned according to user roles, and the check marks represent what permissions this type of role has. Specifically, users can customize usage permissions, and permissions can be divided according to roles, product lines or departments. The circuit component management process is based on the browser-based process management program, which maintains the version and life cycle of circuit components. Different users can enter different roles in circuit component management.

[0043] The device library provided in this application can realize online library construction and online review, which is a very advanced management idea. The Venus library construction tool is seamlessly integrated with the EDM system, thereby realizing online library construction and online review of the library construction project, without relying on the Cadence library construction tool to build the library offline, upload, download and review by the reviewer, and then return to the process for approval and other disconnected operations.

[0044] As a specific embodiment, the present application can first perform task allocation in the device library, then perform schematic library construction and packaging for the task, after the schematic is reviewed, the symbol library is reviewed, and the package library is reviewed, all of which are completed by post-library construction.

[0045] In some embodiments, it also includes: Before outputting the processing result, verifying the processing result; The step of verifying the processing result includes: Verify through the standard library whether the target component properties in the drawing are consistent with the first target instruction requirements.

[0046] Specifically, before exporting the BOM from the EDA tool, perform a standard library check to verify whether the device attributes in the drawing are consistent with the system end, and whether there are any devices that are disabled or restricted. You can also compare BOMs between different versions, use the EDM system to compare, and export the differences into Excel documents.

[0047] The device library provided in this application can also display models, and you can view the device's supply information, electrical parameters, detailed documents, and model previews.

[0048] This application can also submit materials related to circuit components in the device library. The attributes / additional documents of the circuit components that need to be submitted include but are not limited to the following attributes / additions: SCH circuit components, PCB circuit components, test documents, failure cases, etc., characteristic parameters of circuit components, such as current, voltage, power consumption, input and output characteristic parameters, etc. Among them, the parameters related to the circuit components are extracted, such as BOM, material and circuit component version information, and the circuit component thumbnails can be automatically extracted through the EDA client tool to obtain the complete data structure information of the circuit components, which is used for subsequent version management of circuit components, circuit component difference comparison, circuit component replacement and update and other extended functions. The device library provided by this application can also issue reminders for device models or circuit component models, including task reminders: push messages to the relevant responsible persons of the pending tasks of the task nodes; release reminders: after the device model or circuit component model is added and the change process is completed, the message is pushed on the model management system side.

[0049] After the multi-end review process is completed, this application will store the circuit component library, schematic library, and package library files in a shared folder on the server. It supports two calling methods to call the symbol library to the EDA tool. The first is to call it in the Capture / HDL / AD integrated library end, and the second is to call the circuit component in Allegro Design Entry. The latter query, retrieval, and preview are more intuitive, efficient, and easy to modify, which is convenient for automatically extracting parameters related to circuit components through customized development programs, such as BOM, material and circuit component version information, preview circuit diagrams, etc.

[0050] The device library provided in this application can also support parameter management of circuit components, associated documents (design specifications, failure cases, test reports, simulation reports, EDA schematics, etc.), and management of versions of circuit components. Different versions can be compared and traced.

[0051] The EDA design resource library management method provided in this application can provide the creation, import, storage and full life cycle maintenance of general attributes at the component level, circuit component level and circuit level. General attributes include power consumption parameters, power supply parameters, heat dissipation requirements, 3D models, cost factors, rule constraints, key performance and reliability data. Attribute dictionary management is also provided, and users can customize the general attributes at the component level, circuit component level and circuit level, including addition, deletion and modification, and assign permissions to such operations respectively. General attributes include but are not limited to power consumption parameters, power supply parameters, heat dissipation requirements, 3D models, cost factors, rule constraints, key performance and reliability data. The EDA design resource library management method provided in this application supports the centralized management of design rules by the server, supports the addition, deletion, modification, query and association of design rules, and is convenient for viewing on the client. It also supports entry-based, data-based and configurable design rule data maintenance management. It supports free combination of rule sets, can configure rule sets for different products, and can define inspections of different risk levels. It can define mandatory inspection items and optional inspection items, support Checklist to be uploaded in the form of documents, and perform rule disassembly, and support regular backup of rule database. Supports previewing and viewing of rule base content item by item.

[0052] The device library provided by this application is very open and extensible, allowing users to customize new networks and devices, and also allowing users to develop scripts to expand rules, so that the system has more review possibilities, and can quickly implement review rules based on the EDA API, or can be independent of EDA to add algorithms for design review. Weixin PCB inspection software can be independent of the tool, configure rules and manage rule sets separately, and can configure appropriate review rules for different product features and different process routes.

[0053] This application can be reviewed by multiple roles. The review tool is divided into three roles: system administrator, rule administrator and ordinary user. The system administrator can define user permissions and has the highest permissions. The rule administrator can edit the rule base and set the inspection items and parameters in each rule base. The rule administrator can also modify the global name matching rules (including the identification of devices and networks). If you do not actively log in, you are an ordinary user. Ordinary users can only set design-related parameters and view inspection results. The inspection results can output statistics and report functions, and there are two types of statistical reports for single inspection results.

[0054] The EDA design resource library management method provided in this application can standardize the management of EDA design tool graphic symbols, the management of CBB circuit modules, centrally share device symbol library resources, 3D model libraries, and uniformly maintain the integrity, consistency, and effectiveness of device information, avoid redundant data, achieve effective sharing, avoid waste of resources, and at the same time improve the accuracy and reuse rate of design graphics and design data. Relying on complete model and parameter information, further improve the automation of design review, the automation of standardized drawing, and the automation of archiving. Based on the CPU department, a design library management demonstration platform will be established, and after it is mature and online, it will be promoted to other departments and other product applications, ensuring the one-time success rate of products from the source and improving product design efficiency and reliability.
