This article shows you how the Allegro module reuse skills are, the content is concise and easy to understand, can definitely brighten your eyes, through the detailed introduction of this article, I hope you can get something.

Requirement analysis: when using Allegro software for PCB Layout design, when there are many identical modules in the circuit diagram, the operation method of module reuse can significantly improve the work efficiency and make the PCB layout look beautiful as a whole. Let's talk about this method.

Specific methods and instructions:

1. As shown in the figure, the circuits of the two circuit modules in the schematic diagram are the same. For these many identical circuit modules, as long as one of them is done well in PCB, the rest of the same modules can be completed quickly by means of reuse. For those complex modules, the advantage of reuse will be more obvious.

2. Export the device information of the same module in the schematic, and then put all the devices belonging to a module together when placing the device. After placing the device, you only need to select one of the modules for layout and routing, then select Setup-Application Mode-Placement Edit, and then select the finished module. Right-click after selection, and select Place Replicate Create.

3. Set the filter to add via and other information: select other cline, via and shape, and then right-click Done.

Right-click Done after you have selected everything.

4, click the left button will appear a prompt to save the form, the saved file is mdd format, that is, the module definition file, so a module is done.

5, after clicking place replicate create, the elements of the module will be highlighted, and some will not be highlighted-not selected, at this time, you need to select the relevant elements in the right panel, and then select (box selection) in front of the module until all are selected. Via and line cannot be selected. Select other module devices, if less, Allegro will report the devices that cannot be matched, if more, Allegro will ignore the extra devices and only match the devices in the module file.

6, right-click, and then done the command, click the left button, pop-up dialog box, enter the name of the module1.mdd file.

7, use .mdd file for module reuse; in placement edit mode, select all the devices of another module, right-click, right-click after selection, select Place replicate apply, and then select the just saved file name, you can see that the layout and wiring information are exactly the same as before.

The above is what the module reuse skills of Allegro are like. Have you learned any knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
