Method for checking the correlation of circuit board components

A method of inspecting a circuit component, and more particularly to a method of inspecting the correlation of a circuit board component.

With the rapid development of computers, the design of many products has gradually been introduced into Computer Aided Design (CAD). In addition to speeding up the design speed of the product, the introduction of computer-aided design can also effectively record this design and apply it to the improvement of the new version.

In the case of board development assistant software, it is often necessary to set various components in the board configuration process. For example, components such as capacitors, resistors, or chipsets. In order to allow developers and users to easily identify the types of components, various components are marked. Due to the variety of components, the combination of different components will cause memory problems for developers.

In the prior art, the developer can only select different components one by one from the component library for assembly configuration. However, there is a corresponding dependency relationship between the components, so once the developer selects the wrong component, it will cause the loss of the motherboard during manufacturing. Therefore, it is an important issue for developers of computer-aided design programs to solve the problem of finding compatible components from a wide variety of components.

In view of the above problems, it is a primary object of the present invention to provide an inspection method for correlating circuit board components for finding the correlation of circuit components in a circuit board auxiliary design software.

In order to achieve the above object, the method for checking the correlation of the circuit board components disclosed in the present invention includes the steps of: enabling a monitoring program for capturing and recording coordinate values of each component on the circuit board; obtaining a mouse from the monitoring program The coordinate value of the cursor; after selecting at least one component, the trigger signal is sent to the monitoring program by the mouse; the monitoring program searches the geometric image database for the component image of the selected component; if the selected image is present in the geometric image database The component image of the component is loaded into the associated lookup table, and other elements associated with the selected component are found from the associated lookup table; other components found from the associated lookup table are sequentially loaded into the result In the menu.

The present invention provides an inspection method for the relevance of circuit board components used in computer-aided design software. After the developer selects the electronic components, the monitoring program looks for other electronic components that match according to the selected electronic components. As a result, developers will save time searching for electronic components while reducing the risk of mis-planting.

The features and implementations of the present invention are described in detail below with reference to the preferred embodiments.

The monitoring program of the present invention can be applied to different computer-aided design software, such as Auto CAD, Pro/E or Solid works. The computer system 100 to which the present invention is applied includes, as shown in FIG. 1 , which is a schematic diagram of the architecture of the present invention: a storage unit 110, a processing unit 120, a display unit 130, an input device 140, and a computer-aided design software 150. The monitor 160 is associated with the lookup table 170. The storage unit 110 is configured to store the computer auxiliary device and the monitoring program 160. The processing unit 120 simultaneously loads the monitor program 160 when the computer aided design software 150 is executed. The processing unit 120 plots the result of executing the computer aided design software 150 on the display unit 130. The input device 140 is used to input various operation signals to the computer aided design software 150. The type of input device 140 may be: a mouse, a keyboard, or a tablet or the like.

In order to clearly illustrate the operation of the present invention, please refer to "Fig. 2", which is a schematic diagram of the operational flow of the present invention. The method of checking the correlation of circuit board components includes the following steps:

Step S210: When the circuit board auxiliary design software is running, the monitoring program is enabled to capture and record the coordinate value of each component on the circuit board;

Step S220: obtaining a cursor coordinate value of the mouse by the monitoring program;

Step S230: After selecting at least one component, the trigger signal is sent to the monitoring program by the mouse, wherein the comparison is performed according to the cursor coordinate value of the mouse and the coordinate value of the component;

Step S240: The monitoring program searches the geometric image database for the component image of the selected component;

Step S250: If the component image of the selected component exists in the geometric image database, load the associated lookup table, and find other components related to the selected component from the associated lookup table;

Step S260: sequentially loading other components found in the associated lookup table into the result menu;

Step S270: If the component image of the selected component does not exist in the geometric image database, a warning window is displayed to display that there is no corresponding component.

When the computer aided design software 150 is activated, the monitoring program 160 of the present invention can be loaded simultaneously. After the monitor program 160 is loaded, the board file file 310 currently opened by the computer aid design software 150 is checked, and the coordinate value of each component on the board in the board file file 310 is recorded. In addition, the monitoring program 160 simultaneously monitors the current coordinate value of the cursor of the mouse (corresponding to steps S210-S220).

The way in which the mouse selects the component is based on the comparison of the cursor coordinate value of the mouse in the display unit 130 with the coordinate value of the component (corresponding to step S230). For example, select the mouse cursor to select the component, and at the same time the mouse cursor will fall in the area of the component; or drag the mouse to circle the component so that the range selected by the mouse can contain multiple For the components, please refer to "3A" and "3B", which are schematic diagrams of the selected components and the selected components. In the "Fig. 3A", the display unit 130 displays the board file file 310 as an explanation. After completing the action of selecting the components of the board file file 310, the monitoring program 160 receives the presence or absence of a trigger signal from the mouse. When the mouse sends a trigger signal, the monitor 160 acquires the component image of the selected component. The trigger signal can be implemented by pressing a left button, a right button or a scroll wheel of the mouse according to a specific combination of pressing. For example, the trigger signal can be pressed by the right button and the sliding of the wheel.

Next, the monitoring program 160 will begin searching for the component image of the selected component from the geometric image database 180. If the component image of the selected component exists in the geometric image database 180, the association lookup table 170 is loaded, and other components related to the selected component are found from the association lookup table 170 (corresponding to steps S240 to S250). ). Corresponding relationships of other components that each component can match are stored in the geometric image database 180.

After finding other components in the association lookup table 170, the found components are sequentially loaded into the result menu 330. The result menu 330 can be a combo box, a tree, or a list.

For example, because of the number of pins of the network control chip A, the capacitor B, the resistor C, the amplifier D, and the memory E can be matched. Therefore, in the association lookup table 170, the recording network control chip A can be matched to the capacitor B, the resistor C, the amplifier D, and the memory E. The following pull-type menu and the foregoing network control chip A are taken as an example, and the components that can match the network control chip A (the capacitance B, the resistance C, the amplifier D, and the memory E are respectively found from the associated lookup table 170). Then, the capacitor B, the resistor C, the amplifier D and the memory E are successively listed in the pull-down menu. Please refer to "Figure 4", which is a schematic diagram of the pull-down menu.

If the component image of the selected component does not exist in the geometric image database 180, a warning window is displayed to display that there is no corresponding component (corresponding to step S270).

In addition to this embodiment, the present invention can also produce a multi-layered results menu 330 for displaying layers of the same type of elements layer by layer. In this embodiment, the following steps are included, and please refer to "Figure 5":

Step S210: When the circuit board auxiliary design software is running, the monitoring program 160 is enabled to capture and record the coordinate value of each component on the circuit board;

Step S220: obtaining a cursor coordinate value of the mouse by the monitoring program;

Step S230: After selecting at least one component, the trigger signal is sent to the monitoring program by the mouse, wherein the comparison is performed according to the cursor coordinate value of the mouse and the coordinate value of the component;

Step S240: The monitoring program searches the geometric image database for the component image of the selected component;

Step S250: If the component image of the selected component exists in the geometric image database, load the associated lookup table, and find other components related to the selected component from the associated lookup table;

Step S260: sequentially loading other components found in the associated lookup table into the result menu;

Step S261: respectively displayed in the result menu according to the type of the component;

Step S262: Click any element in the current result menu;

Step S263: generating another result menu, and loading the selected component into the newly generated result menu according to the component number of the component;

Step S270: If the component image of the selected component does not exist in the geometric image database, a warning window is displayed to display that there is no corresponding component.

In order to clearly explain the order of the result menus 330 of this embodiment, the first layer result menu 331 and the second layer result menu 332 are sequentially defined in accordance with the order of generation of the result menu 330. However, the number of results menus is not limited to this description, but is described here.

In the above example, the capacitor B, the resistor C, the amplifier D and the memory E matched with the network control chip A are displayed in the first layer result menu 331. When the user clicks on any of the components from the results menu 330, the monitoring program 160 looks up the various item numbers in the associated lookup table 170 that match the component. For example, the capacitor B further includes: a capacitor B-1, a capacitor B-2, a capacitor B-3, and a capacitor B-4. The resistor C further includes a resistor C-1, a resistor C-2, and a resistor C-3.

After the user selects the capacitor B, the monitoring program 160 displays the material numbers of the capacitor B-1, the capacitor B-2, the capacitor B-3 and the capacitor B-4 in the second layer result menu 332, please refer to the "number" Figure 6A shows. Similarly, when the user clicks on the resistor C, the monitoring program 160 displays the resistor C-1, the resistor C-2 and the resistor C-3 in the second layer result menu 332.

The foregoing examples are illustrated by clicking on a single component and finding a matching component. The following is a description of a plurality of components. When the user circles the capacitor I, the capacitor J, the resistor K, the resistor L and the amplifier M, the monitoring program 160 firstly outputs the capacitor I, the capacitor J, the resistor K, the resistor L and the amplifier in the first layer result menu 331. M. When the user clicks on the capacitance I of the first level result menu 331, the monitoring program 160 looks for a matching capacitor in the associated lookup table 170. Assume that the material of the capacitor matching the capacitor I is: capacitor I-1, capacitor I-2 and capacitor I-3. The monitor 160 will generate a second layer result menu 332 and load the capacitor I-1, capacitor I-2 and capacitor I-3 into the results menu, as shown in Figure 6B.

In addition to the display component type and the corresponding item number component, the monitoring program 160 can also obtain the remarks of the component of each item number and the circled component from the association lookup table 170. Since the components are matched, they may be used through special transfers or designs. Therefore, in order to enable other developers to know the technology, the user can store this message in the remarks of the association lookup table 170. When the user clicks on a component with a different item number, the monitoring program 160 will generate a third layer result menu 333 for displaying the corresponding remarks, please refer to "6C".

The present invention provides an inspection method for the correlation of circuit board components used in the computer aided design software 150. After the developer selects the electronic component, the monitoring program 160 looks for other electronic components that match according to the selected electronic component. As a result, developers will save time searching for electronic components while reducing the risk of mis-planting.
