Abstract
A method, system, and computer usable program product for latch clustering with proximity to local clock buffers (LCBs) where an algorithm is used to cluster a plurality of latches into a first plurality of groups in an integrated circuit. A number of groups in the first plurality of groups of clustered latches is determined. A plurality of LCBs are added where a number of added LCBs is the same as the number of groups in the first plurality of groups. A cluster radius for a subset of the first plurality of groups of clustered latches is determined, a group in the subset having a cluster radius that is a maximum cluster radius in the subset. The plurality of latches are reclustered into a second plurality of groups responsive to the maximum cluster radius exceeding a radius threshold, the second plurality of groups exceeding the first plurality of groups by one.
