Abstract
Electronic design automation systems and methods are presented for top-down timing budget flow in master-clone scenarios. In some embodiments, different instances of a master-clone block within an integrated circuit design are associated with different constraint files. The different constraint files are based on the different connections of each instance with elements of the integrated circuit design as well as the shared structure of the master-clone block. A top-down timing budget flow may then be generated based on the differing constraint files, and the integrated circuit design may be modified based on this analysis prior to generation of physical devices based on the design.
