2 to 4 Decoder in Verilog HDL - GeeksforGeeks
https://www.geeksforgeeks.org/2-to-4-decoder-in-verilog-hdl/
A decoder is a combinational logic circuit that converts binary information from n input lines to a maximum of 2^n unique output lines. Below is an example of a 2-to-4 decoder implemented in Verilog.
Example: 2-to-4 Decoder
module decoder24_behaviour(en, a, b, y);
input en, a, b;
output reg [3:0] y;

always @(en or a or b) begin
if (en == 0) begin
case ({a, b})
2'b00: y = 4'b1110;
2'b01: y = 4'b1101;
2'b10: y = 4'b1011;
2'b11: y = 4'b0111;
default: y = 4'bxxxx;
endcase
end else begin
y = 4'b1111;
end
end
endmodule
Testbench for the Decoder
To test the above decoder, you can use the following testbench:
module tb;
reg a, b, en;
wire [3:0] y;

decoder24_behaviour dut(en, a, b, y);

initial begin
$monitor("en=%b a=%b b=%b y=%b", en, a, b, y);
en = 1; a = 1'bx; b = 1'bx; #5;
en = 0; a = 0; b = 0; #5;
en = 0; a = 0; b = 1; #5;
en = 0; a = 1; b = 0; #5;
en = 0; a = 1; b = 1; #5;
$finish;
end
endmodule

2 to 4 Decoder in Verilog HDL - GeeksforGeeks
A decoder is a combinational logic circuit that has ‘n’ input signal lines and 2n output lines. In the 2:4 decoder, we have 2 input lines and 4 output lines. In addition, we provide ‘enable‘ to the input to ensure the decoder is functioning whenever enable is 1 and it is turned off when enable is 0. The truth table, logic … See more

Decoder - VLSI Verify
The decoder behaves exactly opposite of the encoder. They decode already coded input to its decoded form. The ‘N’(=n) input coded lines decode to ‘M’(=2^n) decoded output lines.

How to design a parameterized decoder in Verilog & SystemVerilog?
To design a parameterized decoder in Verilog and SystemVerilog, we can use a logic block to handle any arbitrary number of input bits. This implementation is more concise and efficient compared to using a case statement, especially when the number of input bits is large. parameter EncodeWidth = 4; parameter DecodeWidth = 2 ** EncodeWidth;

How do I use I in Verilog?
For verilog move the 'i' outside the always,make it local to the module integer i; always @( * ) for (i=0... I personally prefer out[i] = (in < i); which makes more clear that in<i returns a one bit value. Beware that for large IN_W this may produce huge amounts of logic.

How does a 4-bit counter work?
The 4-bit counter starts incrementing from 4'b0000 to 4'h1111 and then rolls over back to 4'b0000. It will keep counting as long as it is provided with a running clock and reset is held high. The rollover happens when the most significant bit of the final addition gets discarded.
