Abstract

Modifying a hierarchical circuit design includes accessing hierarchical circuit data in a hierarchical circuit design comprising top level block data and lower level block data; performing timing analysis on a selected portion of the hierarchical circuit data to determine whether timing closure is achieved; and in the event that timing closure is not achieved, determining, within a top level design process, an optimization move on the selected portion of the hierarchical circuit data; wherein the selected portion of the hierarchical circuit data includes a selected portion of the top level block data and a selected portion of the lower level block data.
