Auto Place and Route with Altium Designer

When designing a PCB, in order to improve efficiency, we need to learn how to automatically place and route our projects. In this tutorial, we will introduce the auto place and route in Altium Designer.

Auto Placing Components

1. Select the components to be placed automatically in the PCB, generally according to the circuit module.

Auto Routing

First, open the Altium Designer software, then open your own PCB file.

The final step is to manually modify the routing. Although the auto routing is efficient, there may be deviations in the thickness and direction of some lines, which we need to check and correct manually.
