Lfsr32

See Lfsr5 for explanations.

Build a 32-bit Galois LFSR with taps at bit positions 32, 22, 2, and 1.

module top_module(
    input clk,
    input reset,    // Active-high synchronous reset to 32'h1
    output [31:0] q
); 

    always@ (posedge clk)
        if(reset)
            q <= 32'h1;
    	else begin
            q <= {q[0], q[31:23], q[22] ^ q[0], q[21:3], q[2]^q[0], q[1] ^ q[0]};
