Abstract
Methods, computer program products, and systems for interactively configuring the display of connectivity of a schematic diagram based on an integrated circuit ('IC') design are provided. Using a set of criteria, the schematic diagram can be configured to reduce visual congestion caused by interconnections among circuit elements in the IC design. The criteria include interconnections having a specific number of fan-outs, interconnections connecting ports of specific types, interconnections connecting selected types of circuit elements, and interconnections connecting circuit elements with specific names. The amount of clutter caused by individual nets can also be reduced based on the total congestion score associated with each net. The total congestion score is calculated based on the number of bends that a net makes, the number of crossovers that a net makes, and the number of pixels required to draw the net. Configuration of the connectivity in a schematic diagram is performed through a graphical user interface on a display device, which is connected to a computer system.
