The layout of latches in a common clock domain is efficiently optimized to
shrink the physical size of the domain while maintaining timing
requirements. The latches are placed in a first layout preferably using
quadratic placement, and a star object is built representing an interim
clock structure. The latches are weighted based on wire distance from a
source of the star object, and then re-placed using the weighting. The
weighted placement and repartitioning may be iteratively repeated until a
target number of bins is reached. The boundary of the latches in the
final global placement is used to define a movebound for further detailed
placement.
