net class

The net class is normally created in a cellView using the dbCreateNet() function. A net is not derived from a dbObj, so it cannot have properties. Nets have pins (which represent connections at this level of hierarchy with upper levels of hierarchy) and instPins (which represent connections with instances, i.e. lower levels of hierarchy). These provide a means for hierarchical connectivity from the pins on an instance of the cellView to the instPins on instances in the cellView.
