Description

Method and device for realizing automatic comparison of software line difference

Technical Field

The software principle design part of the Cadence company comprises two types of software, namely concept hdl which is an original tool of Cadence and capture of orcad which is purchased later. Both types of software do not have a circuit diagram difference comparison tool, but nowadays more and more companies use a capture, the circuit diagram comparison tool of the capture is also designed by engineers, and the concept hdl has no more mature circuit comparison tool because the use range is relatively small. For the current increasingly complex product design, the difference of the circuit diagram is compared with the work with large workload and high error rate. The rapid line comparison can enable an engineer to check defects and fill up leakage through software after each modification, and verify whether the difference of the lines meets the design requirement. When teams work cooperatively, if a project which is responsible for by other people is taken over or is responsible for by other people, the mastering of the whole project change by the line change part is very important. If the changed difference part can be classified and displayed through an automatic comparison software, the work can be performed easily, and the improvement on the work efficiency can be increased.

At present, Cadence concept hdl has no mature line difference comparison tool, and the current line comparison mainly depends on manual inspection and comparison by people.

In one embodiment according to the present invention, the line contrast method is implemented by programming via C # programming language, which is an object-oriented high-level programming language published by microsoft that runs on top of NET Framework. In some embodiments, the method can be implemented by parallel multi-process processing, because the number of components in a project is large, and at most, the number of components is ten thousand, and the direct sequential execution of the C # program is very inefficient. Therefore, in one embodiment according to the invention, data can be processed in a multi-thread manner in parallel by calling the task.run () method, and the execution efficiency of software is greatly improved.

The bill of material file and netlist file output by Cadence software are documents that can be converted into csv format, where csv is comma separated value file format, and its files store table data (numbers and text) in plain text form. In one embodiment of the invention, after the bill of material file and the netlist file derived from Cadence concept hdl are converted into the document in the csv format, the document is divided into a plurality of small files according to the names of the components. Because the device names are unique in a project, the device names are adopted to split the whole bill of material file and the netlist file, the whole part is broken into parts, repeated files cannot be generated, and resource waste caused by attribute comparison between a certain device and other devices every time is avoided. In one embodiment, as shown in fig. 1, a bill of material file and a netlist file derived from Cadence concept hdl may be named according to the bit number of each component, and then the bill of material file is named according to the bit number of each component and stored in an a folder, where the file contents are the material number and the loading mode attribute of the component. And naming the netlist file according to the bit number of the component and storing the name into a C folder, wherein the file content is the connection network name of each pin of the component. The other engineering bill of materials file and netlist file are processed according to the above method and finally stored in B, D folders respectively.

A. In one embodiment, as shown in fig. 1, the file in the folder a is used as a project to be compared, and the folder B is used as a reference, the file in the folder a is sequentially moved to the folder B for traversal, if files with the same file name exist, whether the file attributes of the components in the file content are consistent is compared, and the difference points of the files in the folder a relative to the files in the folder B are stored in a final detection document; similarly, the B folder is used as a project to be compared, the A folder is used as a reference, the A folder is sequentially moved into the A folder for traversing according to the files in the B folder, and the difference points in the B folder relative to the files in the A folder are also output to the detection document. C. And D folders respectively store netlist files of two projects, the C folder is used as a project to be compared, the D folder is used as a reference, the D folder is sequentially traversed under the C folder according to files in the C folder, if the D folder does not have files with the same name, the D folder is represented as a newly added component, if the D folder has the same files, the material number values of the components in the file contents and the connection network names of all pins are compared to determine whether the material number values and the connection network names of all the pins are consistent, and difference points in the compared C folder relative to the D file are output to a detection document. Similarly, the D folder is used as a project to be compared, the C folder is used as a reference, the comparison is carried out, and after the comparison is finished, the difference points in the D folder relative to the files in the C folder are also output to the detection document. The detection document can be in the form of an Excel document, and the difference points among the projects are clearly and intuitively displayed for a user.
