Description
Technical Field
The embodiment of the invention relates to the technical field of electronic information, in particular to an intelligent PCB BOM generation method and system.
Background
In electronic circuit design, management of component libraries and management of BOM (Bill of Material) have been two problems that hardware engineers are more troublesome. Most engineers use the AD function of the Altium designer to generate the BOM, but the output BOM lacks some other key information, such as the part number, the quantity, the packaging information and the model number, besides the part number, the quantity, the packaging information and the model number, and cannot be purchased, and the requirement of the standardized BOM format of the company cannot be met. Therefore, the engineer also needs to spend a lot of time to arrange the BOM, add models, manufacturers, etc., and finally copy the BOM to the standardized BOM table template one by one, which is costly in time, e.g., 200 device lists, which generally takes more than 4h (excluding the time for modifying, checking devices, changing schematic diagrams and rearranging the BOM in the middle).
In order to solve the above problems, many enterprises adopt the following processing methods:
the method I is characterized in that parameter information is added into a principle diagram library (or an integration library), and parameter information is added to each component when the principle diagram library (schlib) is manufactured. The most important problem of this method is that the maintainability is poor, for example, the resistor may have thousands or even tens of thousands of different materials due to different resistances, accuracies, models and manufacturers, if the maintenance is performed in this way, an equal number of devices need to be added in schlib, attributes are added to each device, and the process is quite complicated and occupies a large amount of storage space. Similarly, how to share these device libraries is a problem, and most companies put these schlibs or intlibs on a network disk or in a shared folder, so that engineers manually update (copy and paste), which makes it difficult to ensure real-time data and keep information synchronized with the ERP system of the company. Information in a research and development material packaging library is often updated, information in an ERP material management system is not updated, so that purchased materials are inconsistent with research and development designed materials, and finally generated BOMs need to be compared with information in the ERP material management system to complete a final BOM table.
The method II comprises the steps of generating a BOM by using the self-carried function of AD software, then self-researching BOM conversion small software, and combining material parameter information of an ERP-like material management module to generate an enterprise standardized BOM table, wherein although the problem that non-standardized BOM is converted into standardized BOM is solved to a certain extent, the material parameter information of the ERP-like material management module can be synchronized, a process is added in the middle of generation of standardized BOM, and in order to enable software to recognize original BOM, a searched keyword needs to be maintained in component parameters in advance, and the mode improves certain working efficiency but still does not reach the intelligent level.

The ERP system is a highly integrated system applied in the whole company. Data is highly shared among all service systems, and all source data only needs to be input in a certain system once, so that the consistency of the data is ensured. ERP software under the C/S architecture. Namely, the Client and Server structure, reasonably distributes the operating functions of the system to the Client side and the Server side.
The ERP system in the embodiment of the invention adopts an SAP system and provides an SQL Server raw material database. And setting user information and user authority of the access server, wherein the user with the corresponding authority allows corresponding operation. Only one deployment is required.
The ERP system is commonly used by SAP (Germany) system, Oracle (America), domestic ERP systems such as Utility friend, butterfly, Dingjie, forward navigation and the like, and the software systems can also directly or secondarily develop small software to provide an SQL Server database to realize the invention.
And S120, inputting and maintaining material parameter information in the ERP system, and automatically generating an SQL Server database file.
All material parameter information is accurately input and maintained in the SAP material library according to a certain rule, wherein the material parameter information comprises a material name, a material number, specification description, a model, a manufacturer, SCH symbols (consistent with the name in Schlib), PCB packaging (consistent with the name in Pcblib), SCH symbol paths, PCB packaging paths, inventory quantity, Datasheet, design cases, device states, a shelf life, suppliers, prices and the like, and is shown in figure 3.

And S130, inputting and maintaining a PCB component library file at the server side, wherein the PCB component library file comprises SchLib, PcbLib and DbLib files.
The DbLib is one of AD various types of libraries, is called Database Library, and has the idea that a Database (table) is used as a core, and data entries are associated with corresponding schematic diagram symbols and PCB packaging, namely the schematic diagram symbols (or PCB packaging symbols) of a general device can correspond to materials of various types. Such as a resistor symbol, can correspond to a plurality of models. User information and user authority for accessing the server can be set, and users with corresponding authority are allowed to perform corresponding operations. The PCB component library file can be designed and stored on other storage media according to enterprise management requirements.
And S140, establishing and maintaining an enterprise standardized BOM table template warehouse manufactured by using a BOM template library of the AD software at the server side.
In this embodiment, the PCB design software adopts AD software, and cadence and PADS design software, etc. can also replace the functions implemented by the AD software of the present invention.

When the AD is used for designing a schematic diagram, the DbLib library is called directly like loading a common packaging library, information in the DbLib library is material information in an enterprise SAP system, and type selection, data search, component classification and the like can be directly carried out in the DbLib.
And S180, after the schematic diagram design or the PCB design is finished, synchronously updating the information of all the components selected by the design and the component material information of the ERP system.
After the schematic diagram or the PCB is designed, if circuits in other schematic diagrams are used, the final schematic diagram needs to be synchronized with the material information in the ERP system in order to prevent the material information in the ERP system from being changed. Clicking the AD software menu command to keep synchronization with the SQL Server Database, specifically operating, and executing the Tools > > updateParameter From Database command in the schematic diagram editing environment to complete the updating of all device parameters. By executing the Tools > > Update From Libraries command in the schematic editing environment, complete updating of all devices, including parameters, models, packaging, schematic symbols, etc., can be accomplished. The purpose of this step is: the method mainly avoids the situation that the circuit parameters are inconsistent with an SQL Server database, SchLib and PcbLib when the existing circuit is shifted.
