Sometimes I need to design single layer PCB boards to decrease the cost of production , I know that some PCB layout softwares have the ability to autoroute single layers and to solve the unconnectable nets by placing jumpers (as you know that single layer boards usually can't be autorouted all of its netlist without jumpers), I wonder if Protel DXP 2004 has this ability(Placing automatically jumpers for unrouted nets by autorouting).
I installed PowerPcb but I am wonder How can I autoroute my single layer board with jumpers (its help sayed that the autorouter of blazeroute uses 2 layers, the top for only jumpers which deals with it like vias with some constrain 'like only straight lines and with lenght limit'),but I tried to do that with no success , Do you know how?
