I am supposed to create 4 bit full adder verilog code in vivado.But when I try to test in the.It give me z and x output.Which part of code I have to change to get an output in simulation module myfulladder( input A, input B, input CIN, output S, output COUT ); assign S = A^B^CIN; assign COUT = (A&B) (CIN&(A^B)); This is the one bit full adder verilog code I have check the for this code and everything is correct. Module fourbitadder( input 3:0 A, input 3:0 B, input C0, output 3:0 S, output C4 ); wire C1,C2,C3; myfulladder fa0 (A0,B0,C0,S0,C1); myfulladder fa1 (A1,B1,C1,S1,C2); myfulladder fa2 (A2,B2,C2,S2,C3); myfulladder fa3 (A3,B3,C3,S3,C4); endmodule Test bench module test4bit( ); reg 3:0 A; reg 3:0 B; reg C0; wire 3:0 S; wire C4; fourbitadder dut(A,B,C0,S,C4); initial begin A = 4'b0011;B=4'b0011;C0 = 1'b0; #10; A = 4'b1011;B=4'b0111;C0 = 1'b1; #10; A = 4'b1111;B=4'b1111;C0 = 1'b1; #10; end endmodule.Oct 23, 2010 Verilog Serial Adder in Behavioral Description. All variables and given/known data My homework is to design a Serial Adder in Verilog using a shift register module, a full adder module, and a D Flip-Flop module.
