I am writing a ALU with register reading and writing. I have already done all parts except the certain wire that what to set writedata again as the ALUresut and save into one certain register.

Thank you for help.

module lab3B(RegWrite, clock, Read1, Read2, WriteReg, WriteData,

OpcodeField, ALUOp, Zero, ALUResult);

input [4:0] Read1;

input [4:0] Read2;

input [4:0] WriteReg;

input [63:0] WriteData;

input RegWrite;

input clock;

input [10:0] OpcodeField;

input [1:0] ALUOp;

wire [63:0] A;

wire [63:0] B;

wire [63:0] ALUResult;

output Zero;

lab3A RegisterFile(Read1, Read2, WriteReg, WriteData, RegWrite, clock, A, B);

lab2C ALUFile (ALUOp, OpcodeField, A, B, ALUResult, Zero);

endmodule

module lab3A(Read1,

Read2,

WriteReg,

WriteData,

RegWrite,

clock,

A,

B

);

input [4:0] Read1;

input [4:0] Read2;

input [4:0] WriteReg;

input [63:0] WriteData;

input RegWrite;

input clock;

output [63:0] A;

output [63:0] B;

reg [63:0] RF[0:31];//

assign A = RF[Read1];

assign B = RF[Read2];

always@(posedge clock) begin

if(RegWrite) RF[WriteReg]

end

endmodule

module lab2C(ALUOp, OpcodeField, A, B, ALUResult, Zero);

input [1:0] ALUOp;

input [10:0] OpcodeField;

input [63:0] A;

input [63:0] B;

output [63:0] ALUResult;

output Zero;

wire [3:0] ALUOperation;

lab2B ALUControl(ALUOp,OpcodeField,ALUOperation);

lab2A ALU(ALUOperation,A,B,ALUResult,Zero);

endmodule
