Question

using multisim with screen shots Part 8: Create a separate schematic using your newly created 4 bit adder with carry. Verify the operation using at least 4 different input test cases. In at least two test cases, use numbers that make the final Cout active. Note the results and determine the total number of gates needed for your adder.

Answer 1

The student must use Multisim to simulate a 4-bit adder circuit, verify its functionality with different inputs, and calculate the total number of logic gates involved.

Step-by-step explanation:

The question pertains to verifying the operation of a 4-bit adder with carry using the Multisim software. In this case, the student is expected to create a schematic of the 4-bit adder and test its functionality through different input test cases, especially focusing on cases where the final carry out (Cout) is active.

To verify the operation of the adder, the student needs to simulate at least 4 different combinations of input bits and note the outputs, ensuring that the cases cover different scenarios, including when the carry out is expected to be active. Additionally, the question also requires determining the total number of gates used in the adder circuit, which includes counting all individual logic gates such as AND, OR, XOR, and NOT gates that make up the adder.
