Method and apparatus for performing optimization using Don't Care states

摘要

A method for designing a system on a target device includes determining a realization set of a signal that includes one or more representations of the signal where at least one of the representation is influenced by a Don't Care Set (DCS) and all representations are equivalent. The realization set is propagated through the system with the signal. The realization set is used to perform a plurality of separate optimizations on the logic.
