Abstract
A method of limiting the routing resources of an integrated circuit (IC) that are available for use when routing multi-fanout nets can include selecting a multi-fanout net comprising a source and a plurality of loads and identifying each region of the IC which does not include at least one of the plurality of loads. Each of the regions can have a defined geometry. A type of routing resource can be selected which has a physical orientation with respect to the IC that corresponds to the geometry of the regions of the IC. Each routing resource of the selected type that is located within a region of the IC which does not include at least one of the plurality of loads can be excluded from consideration when routing the multi-fanout net.
