Description

Method and device for improving PCB design efficiency

technical field

The invention relates to the technical field of computers, in particular to a method and a device for improving PCB (printed circuit board) design efficiency.

Background technique

The PCB design needs to be realized according to the corresponding circuit schematic diagram. Taking an ordinary communication system user board as an example, the schematic diagram generally has 50 to 100 pages. There are 3,000 to 5,000 devices in one pack. At present, only the netlist is the only information transfer in the process from the schematic diagram to the PCB design, and the netlist only includes device packaging information and connection information, but does not include any device layout information, that is, does not include device location information. This makes the initial layout of thousands of devices in the PCB completely overlapped or randomly arranged in the process of PCB design according to the netlist. For this reason, PCB designers need to invest more time and workload in layout design of each device.

The more advanced method currently in the industry is to define a Room (unit) for each page of the schematic diagram, and the group of devices can be moved in the PCB according to this Room. However, the initial layout of each device in this Room is still random or arranged in the order of the package name or completely overlapped. Then when designing the PCB, it is necessary to carefully check the schematic diagram for each device to understand its role in this module, and then determine its layout position in the module. In this way, it still takes a lot of time Carry out the layout design of each device contained in the PCB.

In short, the methods adopted in the above-mentioned prior art all fail to effectively utilize the location information of the devices in the schematic diagram, resulting in the failure of many efficient layout methods to be used, resulting in long layout design time and heavy workload, and Therefore, it will also lead to an increase in the error rate of PCB design.

Detailed ways

The invention mainly brings the position information of devices in the PCB schematic diagram into PCB design, so that the PCB design is realized based on the position information of each device in the PCB schematic diagram, thereby doubling the efficiency of PCB layout design.

In the PCB, if the relative position of each device is the same as that of the device in the schematic diagram. As an ordinary PCB design engineer, it is easy to understand the relationship between them and the required layout position only by looking at the relative positions of the devices in the PCB diagram. In this way, the layout of more than 95% of the devices can be completed almost without using the schematic diagram when the PCB is laid out, which greatly improves the design efficiency. Although the PCB package size of a device may be quite different from the size of the mark in the schematic diagram, the inconsistency of the device size will not affect the PCB design engineer's analysis of the relationship between the devices.

The concrete realization mode of the method for improving PCB design efficiency described in the present invention is as shown in Figure 1, specifically comprises the following steps:

Step 1: Determine the position information of each device included in the PCB according to the schematic diagram of the PCB to be designed; the position information includes the page number information of each device and the coordinate information in the page number;

In this step, the position information of each device in the PCB schematic diagram is automatically obtained from the electronic file of the PCB schematic diagram, that is, the page number information where each device is located and the specific information in the corresponding page are obtained by analyzing the electronic file. coordinate information.

Step 2: After obtaining the position information, it is also necessary to generate a layout information file that can be recognized by the PCB design tool according to the position information, so as to import the obtained position information into the PCB design file;

The format of the generated layout information file is related to the PCB design tool used during PCB design.

Step 3: according to the determined location information of the components included in the PCB, arrange the components in the PCB design tool;

That is, the PCB design tool imports the layout information file generated according to the position information of each device included in the determined PCB into the corresponding PCB design file;

The essence of the import process of the layout information file is to arrange and display the components contained in the PCB based on the position information of the schematic diagram in the PCB design file.

Step 4: Design the corresponding PCB for each device after the layout is completed;

Specifically: After the PCB design tool arranges the components contained in the PCB on the PCB design page according to the position information of the components in the imported PCB design file, the PCB designer performs corresponding PCB design for each component arranged on the PCB design page ;

Obviously, for PCB design files based on the location information provided by the schematic diagram, PCB designers no longer need to check the schematic diagram frequently, and the workload of re-invested layout design adjustments will be greatly reduced, thereby effectively improving the efficiency of PCB design. It also reduces the error rate of PCB design.

Of course, to generate corresponding PCB design files based on PCB design tools, it is not enough to only have the import of the above-mentioned position information, and the connection relationship information between each device is also required. The present invention mainly adds PCB design files on the basis of generating PCB design files The import process of position information is specified, so there are no restrictions on other elements included in the generated PCB design file.

As shown in Figure 2, the present invention also provides a device for improving PCB design efficiency, including:

Position information acquisition module: automatically analyze the electronic file of the schematic diagram, and obtain the page number information where each device is located and the coordinate information in each page, and then generate the position information as a PCB design tool. The identified layout information file is sent to the position information import module; on the one hand, this module can identify the electronic file of the schematic diagram, so as to obtain the corresponding position information from it; The layout information file that can be identified by the design tool, so that the position information can be successfully imported into the PCB design file to guide the layout settings of each device in the PCB design file.

Position information import module: After receiving the layout information file sent by the position information acquisition module, import it into the PCB tool, and further import it into the corresponding PCB design file, so that each device in the PCB design file is provided by the schematic diagram Position information for corresponding layout settings.

Fig. 3 and Fig. 4 and Fig. 5 respectively provide the display page of the PCB file when the present invention is not applied, and the display page of the PCB file after applying the present invention, it can be clearly seen that the principle diagram provided in Fig. 4 and Fig. 5 The layout information of all pages is imported into the PCB design file, and the display effect is obviously different from that shown in Figure 3, and it is easy to see that PCB design based on Figure 4 and Figure 5 saves a lot of time compared to PCB design based on Figure 3 and workload. As shown in Figures 4 and 5, it only takes a few minutes for the layout information of each page of the schematic to be brought into the PCB.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of changes or modifications within the technical scope disclosed in the present invention.
