Abstract: A system for processing a netlist description of a circuit to generate a display of a schematic diagram including representations of cells and nets first determines positions of the cell instance representations within the schematic diagram and then displays the schematic diagram, including the cell instance representations but no representations of the nets. When a user requests a zoom in operation to display a smaller portion of the schematic diagram at a scale at which net representations can be viewed, the system determines routes for representations of nets that are to reside in that portion of the schematic diagram and then displays those net representations upon zooming in to that portion of the schematic diagram. When the user requests a pan operation to shift the display to another portion of the schematic diagram, the system determines routes for representations of nets that are to reside in that other portion of the schematic diagram and then displays those net representations upon panning to that other portion of the schematic diagram.
