Abstract
A computer-implemented method, and associated system and computer program product, for use in a design process for an integrated circuit (IC) comprises dividing a layout of a metal layer of the IC into a grid comprising a plurality of grid regions, calculating a respective weight for each grid region of the plurality of grid regions, and forming a plurality of groups based on a similarity of the respective weights. Each group of the plurality of groups respectively comprises one or more contiguous grid regions of the plurality of grid regions. The method further comprises assigning each group of the plurality of groups to a respective routing width group type of a plurality of routing width group types, and determining a location for one or more separator cells between adjacent groups of the plurality of groups that are of different routing width group types.
