guys i wanna write a 4-bit complementary 2-bit multiplier circuit in verilog code

Question

module multiplier ();

reg signed [3 : 0] number1;
reg signed [3 : 0] number2;

wire signed [7 : 0] result;

assign result = number1 * number2;

//test bench

initial begin
// -4 * 3
number1 = 4'b1100; //-4
number2 = 4'b0011; //3

// 5 * 6
#1000
number1 = 4'b0101; //5
number2 = 4'b0110; //6

end

endmodule

Answer 1

What language is that?From where you can learn it?

Answer 2

Verilog.

Answer 3

Verilog is that a powerful lang Coder ?what kind of programs you can build with it?

Answer 4

We create circuits, make fulladder,half adder,multipliers with verilog code

Answer 5

It has warnings like memory warnings

Answer 6

@Coder don't you wanna put your test bench and design code in separate files first

Answer 7

Coder what are the errors you get when you run it?

Answer 8

If it is a warning it should work. But if it is an error that's another thing Coder

Answer 9

It's on xilinx. It has warnings so test bech won't run successfully

Answer 10

Coder could you try just with wire instead of wire signed and in the test bench take the - off and try it if it works

Answer 11

Also try to use just reg instead of reg signed. This just to debug and see what my cause the problem
