By a "Flattened PCell" do you mean that you have an instance that's been flattened? If so, the CDF parameters on the device from the PDK library aren't really relevant - you've lost that information when you flattened the instance, and you don't have the data to restore it. Or do you mean that you have somehow messed with the device in the PDK and you can't instantiate it any more as a PCell? (how did you do that?). If so, reinstalling the PDK would make sense. Your question isn't really very clear right now - I'm not sure what you're actually asking! Andrew
