Abstract
A system is provided to perform slack apportionment for an integrated circuit. The system includes a time calculation module and a slack apportion module. The time calculation module determines an arrival time corresponding to a target pin in signal communication with a signal path. The slack apportion module determines a total slack associated with the signal path and determines a slack threshold value that is equal to a portion of the total slack. The time calculation module further determines an apportioned arrival time associated with the signal path based on the arrival time and a delay offset value. The slack apportion module further determines a residual slack apportionment value based on a residual slack and the number of macros associated with the signal path. Accordingly, the time calculation module determines a modified apportioned arrival time based on the residual slack apportionment value and the apportioned arrival time.
