Abstract

See full text

A method and system to route connections of sub-networks in a design of an integrated circuit and a computer program product are described. The system includes a memory device to store instructions to route the connections of the sub-networks, and a processor to execute the instructions to determine a baseline route for each of the connections of each of the sub-networks, identify noise critical sub-networks in the integrated circuit design based on congestion, set a mean threshold length (MTL), segment the connections of the noise critical sub-networks based on the MTL, and re-route the baseline route based on segmenting. The MTL indicates a maximum length of each segment of each connection, each segment includes a different wirecode which is different from a wirecode of an adjacent segment, and each wirecode defines a width, a metal layer, and a spacing for each segment.
