well you can make a not-gate chain ... that works fine and was the first thing i was testing when going into building this adder. I found 2 more porblems: it can't be extended infinitly - i think -because it loses 1 signal strength every bit :/ that has to do with another bug these comparators have where you can't have the back inputs all the same strength. another thing i'm experiencing is that it sometimes just wouldn't work... not in single cases but in some designs. I tried to build another version of my first adder and it did not work. I'm pretty sure it is not timing as i counted the ticks and also tried every other timing... I don't really know why thats happening and how it could work. I definetly have to do more testing.
