Method for checking consistency of schematic diagram and PCB production data

Abstract

The invention discloses a method for checking consistency of a schematic diagram and PCB production data. The method comprises steps as follows: making a standard template of a PCB design software schematic diagram netlist file; making a standard template of an ODB++processing data netlist file; extracting a PCB design software schematic diagram netlist, and extracting a processing data netlist; analyzing the netlists, and storing connecting relation description information, device type information, abidance device information, connection node number, connection nodes and a terminator protocol in a list manner; comparing theschematic diagram netlist file with the processing data netlist file according to a defined data storage protocol; generating a report file according to a comparison result. According to the method, the problems of network loss, short circuit and the like caused by negligence, software bug and the like in a PCB design process are solved, time cost consumed by a designer for connecting relation correction is saved, and the method is better than a currently utilized IPC (inter-process communication) netlist comparison method in the aspects of accuracy and efficiency.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method for verifying the consistency of schematic diagrams and PCB production data. Background technique [0002] The process of conventional PCB printed board design and processing is the process from schematic diagram input to printed board output, from logical description to physical realization. The schematic diagram is a file output by the user, which includes hardware function description, device BOM (bill of materials), and is converted into electronic PCB design data through the network. After completing the PCB design data and inspection, data processing before processing is required. However, in the electronic version In the two processes of PCB data design and pre-process data processing, the hardware connection relationship may cause hardware connection errors due to the designer's professional level, operational errors, and software bugs. Usually, t...

Problems solved by technology

The schematic diagram is a file output by the user, which includes hardware function description, device BOM (bill of materials), and is converted into electronic PCB design data through the network. After completing the PCB design data and inspection, data processing before processing is required. However, in the electronic version In the two processes of PCB data design and pre-process data processing, the hardware connection relationship may cause hardware connection errors due to the professional level of the designer, operational errors, software bugs, etc.

Usually these two processes are difficult to control, and the schematic diagram cannot be traced to the PCB process process, which may lead to omissions in the intermediate process, resulting in production scrap

In the industry, similar quality accidents occur frequently, leading to serious accidents such as project delays and functional failures

The current commonly used method is IPC network comparison, but the limitation is that the content of IPC comparison is the PCB design data network and PCB production data network, which cannot cover the schematic diagram link
