PCB board design - automatic layout 2021-10-15

PCB Cabling yes pcb The most important step in design , The layout of components is correct PCB Wiring speed has an impact , If you can quickly layout various components , Can greatly improve PCB Wiring speed . The following is a summary of Altium Designer Explain the software briefly pcb How the board is automatically laid out ：

First of all, will “ test ” The project file is opened , You can see the schematic diagram and PCB. Here is to “ Brightness adjustable lamp ” Take as an example to explain PCB Quick layout method , Here's the picture ：

Follow this procedure 【Design】->【Validate Changes】->【Execute Changes】->【Close】, Import the drawn schematic diagram into PCB in , Here's the picture ：

 

 
PCB After import , stay PCB There are components in the lower right corner of the board , Then click 【Auto Route】->【ALL】.

 

 
After the above operations are completed , A dialog pops up , As shown in the figure below , Then click... In the dialog box 【Route ALL】, Then there will be “messages” Dialog box .

 

 

In the pop-up “messages” Dialog box , Close this dialog , There will be PCB Wiring diagram , As shown in the figure below ：

This is the result of automatic wiring , What we want is automatic layout , Do not wire . So click 【Tool】->【Un-Route】->【All】. Then the layout without wiring as shown in the figure appears .

 

 

If you want to apply the above automatic layout method, you need to pay attention to the following two points ：
1： This method is applicable to less components , When the quantity is large, you need to adjust it manually .
2： This method combines wiring and layout . It is necessary to remove the thread .
