Question: design a combinational circuit that adds two 4 - bit binary numbers A 3 A 2 A 1 A 0 and B 3 B 2

design a combinational circuit that adds two 4-bit binary numbers A3A2A1A0
and B3B2B1B0 with a carry-in Ci and generates a 4-bit sum S3S2S1S0 and a carry-out Co. Figure 1 shows
the block diagram of this 4-bit binary adder.
Use Logisim to design this circuit using AND, OR, and XOR gates.
Complete table 1.
Table 1. Test cases for the 4-bit binary adder
Try the given test cases in Table 1 in Logisim and check the correctness of your design.
