This example demonstrates an adding circuit for binary numbers, which internally realizes the interconnection to And and to Xor in the final sum.
a b c s t 1 0 1 0 1 0 1 1 0 2 1 1 0 1 3 0 0 0 0 4
t is the pick-up instant of the next bit(s) in the simulation. The simulation stop time should be 5 seconds.
