IMPLEMENTING ENHANCED NET ROUTING CONGESTION RESOLUTION OF NON-RECTANGULAR OR RECTANGULAR HIERARCHICAL MACROS

摘要

A method, system and computer program product are provided for implementing enhanced net routing for congestion resolution of non-rectangular or rectangular hierarchical macro designs of an integrated circuit chip. Congested macro nets near a macro boundary are identified. Wiring channels are reserved outside the macro boundary, allowing congested macro nets to be routed outside the physical boundary of the macro while still being logically contained within the macro.

1. A computer-implemented method for implementing enhanced net routing for congestion resolution of non-rectangular or rectangular hierarchical macro designs of an integrated circuit chip comprising:
a computer system performing method steps of: identifying congested macro nets near a macro boundary; and reserving wiring channels outside the macro boundary, allowing congested macro nets to be routed outside the physical boundary of the macro while still being logically contained within the macro; said reserved wiring channels implementing the identified congested macro nets near said macro boundary.
