Problems solved by technology

After different EDA software is imported into ODB++, problems such as lack of copper skin and vias can be solved, but because it is a standard that is biased towards PCB processing files, the electrical properties of the components (such as the model name of the capacitor and the name of the capacitor package) are adjusted. Due to the differences of different PCB design software and the non-standard design, there may be problems. In this case, if you want to modify the electrical properties of the imported ODB++ file, it is not convenient or fundamental to modify the original PCB file in the original EDA software. it works

specific Embodiment

[0051] Taking the Sigrity PI simulation platform of CADENCE manufacturer as an example (applicable to PI simulation platforms of other EDA software vendors), other software PCB design tools output standard ODB++ files. According to the third-party BOM information in the PCB file or provided independently, there are mainly three columns: the label of the component, the name of the package-related information, and the value (this column is missing)), in order to facilitate the identification of different capacitors in the PI platform later Combine the package name and value in the above figure, and the following programs will use these three columns as processing objects. Finally, organize the numbers into a file named reflist.txt.

[0052] Use the program to process the table and the components file under the subdirectory (…\layers\comp_+_top\…\layers\comp_+_bot\) in the odb++ file. Finally, process the bom table and components file through the program, modify the correspondin...

Abstract

The invention discloses an ODB++ file modification method and device and a readable storage medium. The method comprises: S1: acquiring a BOM list of a third party, which is in a PCB file or is independently provided, wherein the list comprises a label column of components, a packaging column of the components and a numerical column of the components; S2: forming a model base name column by the packaging column of the components and the numerical column of the components in the BOM list, and covering the original packaging column with the formed column to form an update list file; and S3: according to the update list file, modifying corresponding contents of a Components file in an ODB++ file and carrying out storage. The invention solves the problem that ODB++ files designed by differentEDA software are called by a third-party PI (Power Integrity) simulation platform, component information is wrong or turned over. Therefore, the modified ODB++ file is applicable to all PCB PI simulation platforms, convenient to use and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of power integrity simulation, in particular to an ODB++ file modification method, device and readable storage medium. Background technique [0002] ODB++ is an extensible ASCII format that holds all engineering data necessary for PCB fabrication and assembly in a single database. A single file can contain graphics, drilling information, routing, components, netlists, specifications, drawings, engineering process definitions, reporting functions, ECO and DFM results, and more. Operators can refine and correct DFMs to update their original CAD databases and try to identify any routing issues before the design reaches the assembly stage. ODB++ is a bidirectional format, allowing data to be uploaded and downloaded. ODB++ databases are similar to the databases of most CAD systems. Once the data reaches the board shop in ASCII form, fabricators can implement value-added process operations such as etch compensa...
