摘要

Today let's drop the manual PCB design work and look at DesignSpark's automatic routing tools. If you've never used an automatic PCB track router ("autorouter") before, today is the day. We'll start by introducing the autorouter and then we'll see how to configure and use it. A PCB autorouter can route some or all of your circuit board for you using a set of predefined rules. Most autorouters, including DesignSpark's, use shape based multipass technology which gives them a better chance to completely route a board. Grid based autorouters use a grid where only 1 trace or feature could occupy each location at a time but this makes it difficult to route complex boards with a lot of traces. However, a shaped based autorouter uses the actual copper shapes on the board to determine where to route the traces which allows the autorouter to pack the traces as tight as possible in a given area. The DesignSpark autorouter is also a multipass router which means it will try and route a board repeatedly until all of the routing errors are gone or the number of tries has been exhausted.
