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