Question

Write a behavioral module for a full-adder in Verilog. Draw the block diagram for an 8-bit unsigned adder. Draw the block diagram for an 8-bit unsigned multiplier. Use 8-bit ripple-carry adders instead of full adders in your diagram. Use bus notation where appropriate. To simplify your diagram, you may only use one AND gate per row. The implicit notation here is that (A[7:0] AND B[0]) implies that B[0] is AND'ed bitwise with A[7:0]. Write major bus names on your diagram. For the 8-bit unsigned multiplier, give the minimum and maximum value of the input operands and the minimum and maximum value of the output product. How many bits are needed at the output of the multiplier to ensure that all possible products can be fully represented?

Explanation / Answer

module full_adder(a,b,cin,sum,cout);
input a,b,cin;
output reg sum,cout;

always@(*) begin

{cout,sum}=a+b+cin;

end
endmodule
