Automatic Routing—PCB Wizard 3 includes an advanced automatic router that is able to route single-layer and double-layer boards. Available with a brand new 'rip-up and retry' algorithm rather than the 'single-pass' method used in previous versions, PCB Wizard 3 achieves extremely high completion rates by going back and re-routing nets to make space for connections that could not be routed on a previous pass. Note that the Standard edition supports single-sided routing only.
