What time period are you referring to? Just to clarify, the destruction of Carthage in 146 B.C. did not really spell the end of Carthaginian civilization; most of the other Phoenician/Punic cities survived, while the Numidian kings seem to have adopted Carthaginian administrative, economic, and religious institutions among other things. The Romans themselves eventually built another Carthage in the first century B.C., and it stood until the Umayyads razed it in 698 A.D. As late as the fifth century A.D., as we know from Saint Augustine, many North Africans continued to speak Punic and identify themselves as Canaanites. I am otherwise unaware of any more recent attempts to culturally "revive" Carthage. According to Wikipedia, the area is now a suburb of Tunis. :)
