Sometimes high-speed signal nets have series resistors between the driver and receiver pins. The resistor divides the trace to create two physical nets on both sides of the resistor. HyperLynx DRC combines the two physical nets creating an electrical net. When a net is divided by a series component, HyperLynx DRC automatically combines the segments to create an electrical net. All the other physical nets except constant nets are identical to the associated electrical nets.
