用verilog设计一个8位正整数全加器

很高兴为您解答这个问题！可以使用如下的verilog代码来设计一个8位正整数全加器：

module full_adder(
    input A,
    input B,
    input carry_in,
    output sum,
    output carry_out
);

assign sum = A ^ B ^ carry_in;
assign carry_out = (A & B) | (carry_in & (A ^ B));

endmodule

module eight_bit_adder(
    input [7:0] A,
    input [7:0] B,
    input carry_in,
    output [7:0] sum,
    output carry_out
);

wire [7:0] s;

full_adder fa0(A[0], B[0], carry_in, s[0], co0);
full_adder fa1(A[1], B[1], co0, s[1], co1);
full_adder fa2(A[2], B[2], co1, s[2], co2);
full_adder fa3(A[3], B[3], co2, s[3], co3);
full_adder fa4(A[4], B[4], co3, s[4], co4);
full_adder fa5(A[5], B[5], co4, s[5], co5);
full_adder fa6(A[6], B[6], co5, s[6], co6);
full_adder fa7(A[7], B[7], co6, s[7], carry_out);

assign sum = s;

endmodule
