Conversion method for file format of circuit board view program

Abstract

The invention discloses a conversion method for the file format of a circuit board view program, wherein the original binary data file exported by the circuit board view program is converted into a file supported by a new version. The conversion method comprises the following steps: because of newly adding a functional module and an element data logic organization, physically storing a structural change, and binding the matched data logical structure with a data physical storage structure to form a dynamic linking file; loading a binary data file provided with the data logical structure and the data physical storage structure; automatically matching the corresponding logic structure through a data logic and a physic structure mapping in a middle layer, and realizing the data loading and show of the file by the logical structure structurally matched with the data physical storage structure from the dynamic linking file of the corresponding version number to generate a view file if the physical storage structure of the binary data file does not accord with the logical structure of the current version.

Description

technical field [0001] The invention relates to a file conversion method, in particular to a file format conversion method of a circuit board viewing program. Background technique [0002] In the process of developing electronic products, circuit board data files need to be processed frequently. The factory area usually uses text format circuit board data files (Computer-aided design, referred to as CAD), but due to the huge consumption of resources (for example, graphing calculators require high-level processors or large-capacity memory, large-size text data leads to network transmission efficiency Low), it is really a big burden for factories that frequently upload, download, and use text data CAD with high frequency. Therefore, in order to achieve efficient, fast, sustainable and smooth processing of circuit board files, another manufacturer has proposed a circuit board viewing program (Board Viewer). Since the circuit board viewing program does not require a large amou...

Problems solved by technology

Every upgrade of the data structure of the circuit board viewing program requires re-conversion of the original binary data file, which seriously affects the ease of use and maintainability of the binary data file, and it is very likely to become a circuit board based on binary data applications. The stumbling block to the comprehensive promotion of viewing programs and related derivative systems
