Debugging Combinational Multiplier
A 3x3 combinational multiplier computes the 6-bit product of two 3-bit unsigned integers. Custom multipliers require precise alignment of partial products to ensure correct accumulation.
Expected behavior:
The output P must exactly equal the arithmetic product of inputs A and B.
Simulation shows P = 9 for prime inputs A = 3 and B = 5. The expected output is 15. Another test case with prime inputs A = 7 and B = 5 outputs 21 instead of 35. The output is systematically incorrect for specific input combinations where the third bit is high. Inspect the circuit and correct the fault.
Constraints
- Do not modify the logic generating the first two partial products.
- Ensure the final product
Premains a 6-bit unsigned value. - Only standard combinational logic gates and wiring may be used.
