I have 4 DDR address lines that go to one RPAK that has four individual resistors. All of the resistors are tied to 0.75 volts one side. When I select one of the address lines, all four are selected because it is routing through the 0.75V power plane. Is there anyway to stop "Select Net" from routing through a ground plane? Is there an easy way to cut a trace when the design is in BoardSim? Any help would be appreciated.
Have you defined the 0.75V net as power supply net (Setup -> Power Supplies…)? You can also unroute a net from Edit -> Unroute Routed Nets…
