A computer readable media for use with a computer system having a processor coupled to a memory via a bus, the computer readable media having computer readable code stored thereon, which when executed by the computer system, cause the computer system to perform a method for implementing a graphical user interface for depicting loose fly line interconnections between multiple blocks of an integrated circuit netlist, the method comprising:
- a) accessing an input file containing identifications of a plurality of blocks of cells of said integrated circuit netlist, each block representing circuit components to be realized in physical form;
- b) presenting a view of the plurality blocks to a user, the view provided by a computer display;
- c) graphically depicting connection relationships between the plurality of blocks;
- and
- d) altering the depiction of the connection relationships between the plurality of blocks in accordance with a number of logical elements connected between the plurality of blocks to show connectivity relationships of the integrated circuit netlist, wherein the depiction of step c) can be adjusted to different hierarchical levels to show the connection relationships at a higher level or a lower level.
