In this lecture you are going to learn how to using the routing and autorouting tool in Altium Designer. So once we have all the components on the board and placed, we then proceed to route the components and then also we auto-route the board to save time and effort routing.
In electronic design, wire routing, commonly called simply routing, is a step in the design of printed circuit boards (PCBs) and integrated circuits (ICs). It builds on a preceding step, called placement, which determines the location of each active element of an IC or component on a PCB. After placement, the routing step adds wires needed to properly connect the placed components while obeying all design rules for the IC.
