Part 1 1bit verilog code
Form the 4-bit RCA, using the one-bit full adder from Part
1.
Apply logic levels 0 and 1 to the inputs of the circuit, satisfying
every entry of the truth
table, and recording the output values.
To achieve this, apply B[3:0] = 0000 and Carry-In = 0 while
changing A[3:0] from 0000
to 1111 as the first step. Compare all 16 Sum and Carry-Out outputs
against the expected
outputs at each entry.
In the next step, repeat the same experiment by changing A[3:0]
from 0000 to 1111 for
each B[3:0] from 0001 to 1111 while keeping Carry-In = 0 (the
remaining 15x16 = 240
cases). Again compare the Sum and Carry-Out outputs against
expected outputs for each
case with truth table.
