welp
finally found the real world equivalent for CCA, took me a while. That carry chain looks exactly like the CMOS chain I designed for my real world implementation.
>propagate-kill circuit
ayyyyyyyyyyyyyyyyyyyyyyyyy
I think it's kinda cool I designed this independently though, this is a pretty obscure algorithm. Found it through searching "complementary transistor carry chain".
on second thought, my implementation is slightly different with an implicit propogate instead of their generate, but essentially it all boils down to the same thing.
On further searching, later iterations in other patents referencing this get even closer to my design lol https://www.google.com/patents/US6367059

I should go grab that logism file off my old laptop for comparison. will go grab it this evening. (the logism screenshot earlier in this thread is different, modelling the MC implementation)
