CAN YOU HELP ME IN MY VERILOG HDL CODE, THERE ARE SOME MISTAKES
// Company: METU-NCC // Engineer: Your name goes here // Create Date: Date goes here // Design Name: Full Adder // Module Name: fulladd - Logicfunc // Project Name: Lab 1 // Target Devices: Cyclone III EP3C16F484C6 // Description: Full adder Verilog design // Dependencies: List code modules called by this module none here. // Revision: // Revision 0.01 - File Created // Additional Comments: Information to make the code easier to follow. //Structural Approach// module fulladd (A,B,Cin,S,Cout); output S,Cout; input A,B,Cin; wire w1,w2,w3; xor G1(w1,Cin,A,B); or G2(w1,A,B), G3(w2,A,Cin), G4(w3,B,Cin); endmodule G5(Cout,w1,w2,w3); endmodule
