Project 2 Recursion, test issues

Is there any problem with the testing Program?

i finished it all, no compatible issues and everything is 0.

for example i added the second circuit, bit wise OR 4_4 that is also zero.
what should i do?
is there another place i can send my project?

In Regards, Lior

You probably have some issues with the locations of the I/O pins in the blackbox design of the circuit. Did you manage to fix it already, or do you still need help?

Yes the problem was that i loaded project 1 as a library, fixed, thanks
