Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic automation, and in particular, relates to a PCB independent network checking method and device, computer equipment and a storage medium. BACKGROUND

[0002] With the increasing complexity of PCB (Printed Circuit Board) design, more and more devices are on the PCB, and the volume of components is getting smaller. For PCB design, the PCB schematic diagram is generally designed first, and then the PCB schematic diagram is synchronized to the PCB design file.

[0003] In the PCB schematic diagram making, when connecting the device pins with lines, it is difficult to avoid not connecting due to the schematic diagram connection points or other lines blocking, etc. For example, as shown in FIG. 1, in the design, it is hoped that the pin 1 and the pin 2 are connected with the pins of another device at the same time, and the actual made schematic diagram is as shown in FIG. 2. Figure 1 In the making diagram, line 1 is connected with line 2, and line 1 and line 2 are not connected with line 3, which obviously does not meet the design requirements, but it is difficult to see that line 3 is not connected with line 1 and line 2 by naked eyes. Figure 1

[0004] In addition, since the pin 1 and the pin 2 in the making diagram have formed a network connection and have connectivity, the design process will not report an error. When the PCB schematic diagram is synchronized to the PCB design file, since the PCB package diagram itself has network connectivity, the error will not be checked in the PCB design file process, and there is a certain checking omission.

[0005] In order to ensure the accuracy of the schematic diagram, the existing technology generally adopts the way of manually moving the schematic diagram connection line by manual work to check whether the connection line is disconnected to ensure that the made schematic diagram is consistent with the actual requirements. Specifically, line 3 is moved, since line 3 is not connected with line 1 and line 2, the result shown in the checking diagram in FIG. 3 is obtained, and the problem is found. Figure 1

[0006] In the existing technology, the way of manually checking the schematic diagram connection line by manual work is needed to determine whether the line connection is correct, which has a large workload, low efficiency, and is easy to cause missed detection due to manual negligence. SUMMARY

[0064] In order to make the above objectives, features and advantages of the present application more apparent, further specific embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0065] First, the terms are defined and explained:

[0066] PCB: Printed Circuit Board, printed circuit board; is an important electronic component, is the support of electronic components, is the carrier of electrical connection between electronic components.

[0067] PCB package diagram: PCB-Package, indicating the parameters of components (such as length and width, size of pads, spacing, etc.) diagram, used to call when drawing PCB.

[0068] PCB network: PCBNet, the network formed by the mutual connection of component pins, determines a connection relationship.

[0069] Network name: give the name of this connection relationship, that is, the network name, the default with the same network name has a connection relationship.

[0070] Independent network: IndependentNet, abbreviated as INDNet, refers to the connection of two or more pins on a single PCB package diagram to form a network, and the network is not connected to other PCB package diagram pins, that is, the network of only the pins of the PCB package diagram are interconnected.

[0071] Script: is an extension of batch files, is a kind of program saved in pure text.

[0072] In one embodiment, as shown in Figure 2 A PCB independent network checking method is provided. The method can be applied to the PCB design stage to check the PCB independent network to find the specific location of the pin connected by the independent network. The method can be executed by a PCB independent network checking device, which can be implemented in software and / or hardware and integrated into a PCB design device or a third-party electronic device.

[0073] In this embodiment, the method can include the following steps:

[0074] Step 101, determine the PCB package diagram contained in the to-be-inspected PCB.

[0075] Step 102, determine the pins corresponding to each PCB package diagram.

[0076] Wherein, the to-be-inspected PCB refers to the PCB to be checked for the PCB independent network. The PCB contains multiple PCB package diagrams, and each PCB package diagram includes multiple pins.

[0077] It should be noted that in the PCB design, multiple PCB package diagrams in the same PCB have a unique corresponding package identifier; the pins in the same PCB package diagram have a unique corresponding pin identifier. However, different PCB package diagrams can contain pins with the same pin identifier. Wherein, the package identifier can be the name or serial number of the PCB package diagram, which can serve as a unique identifier; the pin identifier can be the serial number of the pin in the corresponding PCB package diagram, which can serve as a unique identifier within the corresponding PCB package diagram.

[0078] In this embodiment, by determining the PCB package diagram contained in the to-be-inspected PCB and recording the package identifier of each PCB package diagram, for each PCB package diagram, further determine the pins corresponding to the PCB package diagram, i.e. the pins contained in the PCB package diagram, record the pin identifier of each pin, and at the same time, establish the corresponding relationship between the pin identifier and the package identifier, so that in the subsequent process of checking the PCB independent network, the corresponding PCB package diagram of the pin of the independent network can be determined according to the above-mentioned corresponding relationship, and then the specific location of the pin can be quickly located when the independent network is processed subsequently, facilitating subsequent processing and improving the efficiency of subsequent processing.

[0079] Step 103, obtain the connection information of each pin; the connection information includes the PCB package diagram connected to the pin line.

[0080] Step 104, when the PCB package graph in the connection information only contains the PCB package graph to which the pin belongs, it is determined that the network corresponding to the pin is an independent network.

[0081] In this embodiment, for each PCB package graph, each pin in the PCB package graph is sequentially traversed, for each pin, the line connected by the pin is determined, and then the PCB package graph connected by the line is acquired, and the set of all PCB package graphs connected by the line connected by the pin is taken as the connection information of the pin.

[0082] In a specific implementation, when a pin has no connected line, it can be considered that the PCB package graph in the connection information of the pin is empty, and it is determined that the network corresponding to the pin is a single-ended network.

[0083] Exemplarily, as shown in Figure 3 , Figure 3 a schematic diagram of a to-be-inspected PCB provided in this embodiment; the to-be-inspected PCB includes a PCB package graph U1 and a PCB package graph U2; the PCB package graph U1 includes eight pins, and the corresponding pin identifiers are Pin1-Pin8 respectively; the PCB package graph U2 includes four pins, and the corresponding pin identifiers are Pin1-Pin4 respectively.

[0084] Taking the pin Pin1 of the PCB package graph U1 as an example, the pin Pin1 has no connected line, and therefore, it is determined that the network corresponding to the pin Pin1 is a single-ended network.

[0085] Alternatively, when the other end of the line connected by a pin is not connected to a pin of any PCB package graph, it can also be considered that the PCB package graph in the connection information of the pin is empty, and it is determined that the network corresponding to the pin is a single-ended network.

[0086] Exemplarily, taking the pin Pin2 of the PCB package graph U1 in Figure 3 as an example, the pin Pin2 is connected to a line, but the other end of the line is not connected to a pin of any PCB package graph, and therefore, it is determined that the network corresponding to the pin Pin2 is a single-ended network.

[0087] It can be understood that a single-ended network, also known as a single-point network, refers to a network in which only one pin of one package is connected, and the network is not connected to the pin of the same package and other pins of other packages.

[0088] When the other end of the line connected by a pin is connected to a pin of a PCB package graph other than the PCB package graph to which the pin belongs, it is considered that the PCB package graph in the connection information of the pin is the other PCB package graph, and it is determined that the network corresponding to the pin is a non-independent network.

[0089] Exemplarily, taking the pin Pin3 of the PCB package graph U1 in Figure 3For example, the pin Pin5 of the PCB package U1 in the figure is taken as an example. The other end of the line of the pin Pin5 is connected to the pin Pin2 of the PCB package U2. Therefore, the network corresponding to the pin Pin5 is a non-independent network.

[0090] Alternatively, when the other end of the line connected by a pin is connected to other pins of the PCB package to which the pin belongs and to pins of other PCB packages outside the PCB package to which the pin belongs, the PCB package in the connection information of the pin is considered to be the set of the PCB package to which the pin belongs and the other PCB packages, and it is determined that the network corresponding to the pin is a non-independent network.

[0091] For example, the pin Pin6 of the PCB package U1 in the figure is taken as an example. The other end of the line of the pin Pin6 is connected to the pin Pin1 of the PCB package U2 and to the pin Pin7 of the PCB package U1. Therefore, the network corresponding to the pin Pin6 is a non-independent network. Figure 3 It can be understood that the non-independent network refers to a PCB network in which the pins of two or more packages are connected.

[0092] When the other end of the line connected by a pin is connected to only other pins of the PCB package to which the pin belongs, the PCB package in the connection information of the pin is considered to be the PCB package to which the pin belongs, and it is determined that the network corresponding to the pin is an independent network.

[0093] For example, the pin Pin3 of the PCB package U1 in the figure is taken as an example. The other end of the line of the pin Pin3 is connected to the pin Pin4 of the PCB package U1. Therefore, the network corresponding to the pin Pin3 is an independent network.

[0094] Figure 3 It can be understood that the independent network refers to a PCB network in which two or more pins of one package are connected.

[0095] It can be understood that the independent network refers to a PCB network in which two or more pins of one package are connected.

[0096] According to the connection information of each pin in each PCB package, the network type corresponding to each pin can be determined, and the pin can be marked according to the network type. The network type includes an independent network, a non-independent network, and a single-ended network.

[0097] It should be noted that in an optional embodiment, when the actual requirement is to check the independent network, when determining the network type corresponding to the pin according to the connection information of the pin, only the independent network type can be determined and marked.

[0098] In step 105, the information of the independent network is recorded.

[0099] ​In the embodiment, information of the independent network needs to be recorded so as to determine whether the independent network meets the actual design requirement.

[0100] Specifically, the information of the independent network can include:

[0101] The pin identification of the pin connected to the independent network and the package identification of the PCB package to which the pin belongs are recorded in the inspection result report according to a preset specification.

[0102] In actual application, the preset specification can be represented by an inspection result report template. When it is determined that the network corresponding to the pin is an independent network, the pin identification of each pin connected to the independent network and the package identification of the PCB package to which the pin belongs are filled in the corresponding position of the inspection result report template to obtain the inspection result report. Moreover, when the network corresponding to the pin is an independent network in subsequent inspection, it can be determined whether the independent network has been recorded in the inspection result report. If the information of the independent network has been recorded in the inspection result report, the subsequent inspection is skipped. If the information of the independent network has not been recorded in the inspection result report, the pin identification of each pin connected to the independent network and the package identification of the PCB package to which the pin belongs are filled in the obtained inspection result report.

[0103] Generally, one PCB corresponds to one inspection result report, that is, the information of the independent network in one PCB is recorded in one inspection result report. Alternatively, one PCB package corresponds to one inspection result report, that is, the information of the independent network in one PCB package is recorded in one inspection result report.

[0104] Optionally, the recording of the pin identification of the pin connected to the independent network and the package identification of the PCB package to which the pin belongs in the inspection result report according to the preset specification can further include:

[0105] The coordinate position of the pin connected to the independent network in the PCB is recorded in the inspection report.

[0106] In the embodiment, the coordinate position of each pin in the PCB can be recorded in the inspection result report in addition to the pin identification of the pin connected to the independent network, so that the pins connected to the independent network can be quickly located in subsequent processing.

[0107] Specifically, during the PCB design process, the PCB design diagram thereof can be placed in a plane rectangular coordinate system. When the independent network is determined, the coordinate position of the pin can be determined according to the position of the pin connected to the independent network in the PCB, and the coordinate position information is recorded in the corresponding area of the inspection result report.

[0108] Further, the method can further include:

[0109] The inspection result report is displayed.

[0110] In this embodiment, when the inspection result report is generated or new information about the independent network is added in the inspection result report, the inspection result report is displayed on the corresponding display interface. Alternatively, when all the pins of the PCB or the PCB package diagram corresponding to the inspection result report are checked, the inspection result report is displayed on the corresponding display interface.

[0111] Further, the above method can further include:

[0112] receiving a display instruction; the display instruction includes a target PCB identifier;

[0113] obtaining a target inspection result report corresponding to the target PCB from a plurality of inspection result reports;

[0114] displaying the target inspection result report.

[0115] In this embodiment, when all the pins of the PCB or the PCB package diagram corresponding to the inspection result report are checked, the inspection result report can be saved. Therefore, a plurality of inspection result reports that have been checked can be stored. When a user needs to check the independent network inspection result of a certain PCB or the independent network inspection result of a certain PCB package diagram, a related display instruction can be sent, and when the display instruction is received, a target inspection result report can be determined according to the target PCB identifier or the target package identifier of the target PCB package diagram in the display instruction, and the target inspection result report is displayed on the display interface.

[0116] Further, the above method can further include:

[0117] receiving a trigger operation on a coordinate position of a pin in the inspection result report;

[0118] marking the pin at the coordinate position in the PCB corresponding to the inspection result report.

[0119] In this embodiment, the coordinate position of the pin of the independent network is recorded in the inspection result report, and the coordinate position can be linked to the actual position of the pin in the PCB. When a trigger operation on the coordinate position of any pin in the inspection result report is received, the pin at the coordinate position can be marked in the PCB corresponding to the inspection result report. The trigger operation can be a click operation, such as a single click or a double click.

[0120] For example, when a user clicks the coordinate position of any pin in the inspection result report, the interface can jump to the PCB design diagram corresponding to the inspection result report and locate the pin at the coordinate position clicked by the user, thereby facilitating the user to perform troubleshooting and correction and the like.

[0121] In the embodiment of the application, the PCB package diagram contained in the to-be-inspected PCB is determined; the pins corresponding to each PCB package diagram are determined; the connection information of each pin is obtained; the connection information includes the PCB package diagram connected with the pin line; when the PCB package diagram in the connection information only includes the PCB package diagram to which the pin belongs, it is determined that the network corresponding to the pin is an independent network; and the information of the independent network is recorded. The independent network of the PCB can be automatically inspected, and the related information of the independent network can be automatically recorded, which is high in accuracy and efficiency.

[0122] In order to facilitate the understanding of those skilled in the art, the PCB independent network inspection method provided by the embodiment of the application will be described in detail below in combination with specific examples.

[0123] The PCB independent network inspection method provided by the embodiment of the application can be written in SKILL language, created into a script file, loaded in the software of electronic design automation (EDA), and simultaneously generate corresponding inspection controls, for example, loaded in the Allegro PCB Editor module toolbar of the Cadence software. When used, the user can automatically load and run the script file corresponding to the PCB independent network inspection method by triggering the inspection control, and the PCB package diagram in the PCB is checked one by one by running the script file, and the inspection process shown in the following figure is performed. Figure 4

[0124] Step 401, determining the PCB package diagram of the PCB; specifically, each PCB package diagram can be determined according to the package name of the PCB package diagram contained in the PCB;

[0125] Step 402, determining the pin of the PCB package diagram; specifically, each pin can be determined according to the pin serial number of the pin contained in each PCB package diagram;

[0126] Step 403, obtaining the connection information of the pin;

[0127] Step 404, determining whether the network corresponding to the pin is an independent network according to the connection information; if yes, step 405 is performed; if no, step 406 is performed;

[0128] Step 405, recording the related information of the independent network, if the related information has been recorded, ignoring and continuing to perform step 307;

[0129] Step 406, not recording and continuing to perform step 407;

[0130] Step 407, checking the next pin and returning to step 403;

[0131] Step 408, checking the next PCB package diagram and returning to step 402; ​

[0132] Step 409, check ends, output check results.

[0133] By checking the PCB package diagram in the PCB one by one, for each PCB package diagram, the pins in the PCB package diagram are checked one by one, after a PCB package diagram is checked, the next PCB package diagram is checked, until all PCB package diagrams of the PCB are checked. After checking, the check result report is output in the corresponding interface, which can be a log file.
