Abstract
Some embodiments provide a method of routing nets within a region of an integrated-circuit ('IC') layout. The method uses a first set of lines to partition the IC region into a plurality of sub-regions. In addition, the method uses a second set of lines to measure congestion of routes for the nets within the IC region. According to this method, at least some of the lines in the second set are different from the lines in the first set.
