LFSR is a shift register whose random state at the output depends on the feedback polynomial. So it can count maximum 2n-1 states and produce pseudo-random number of the output. By using FPGA, comparing 8 and 16 bit LFSR on the basis of memory, gates. Index Terms-LFSR, FPGA, Verilog HDL, pseudo-random number, TRNG, PRNG. I. INTRODUCTION

Link: http://simplefpga.blogspot.co.uk/2013/02/random-number-generator-in-verilog-fpga.html • An LFSR generates periodic sequence – must start in a non-zero state, • The maximum-length of an LFSR sequence is 2n-1 – does not generate all 0s pattern (gets stuck in that state) • The characteristic polynomial of an LFSR generating a maximum-length sequence is a primitive polynomial • A maximum-length sequence is pseudo-random: LFSR stands for linear feedback shift register. Although they are widely used in random electronics projects but they are quiet often neglected by the engineers community. LFSR is comprised of a series of D-flip flops, depending on the size of the LFSR. Some of the states and especially the last one is feed back to the… Labels: LFSR verilog Code.

Basically, the idea behind an LFSR is that given a current register state, I’ll call it a “fill”, you can compute the next state via a linear combination of the bits in the current state. This page contains SystemVerilog tutorial, SystemVerilog Syntax, SystemVerilog Quick Reference, DPI, SystemVerilog Assertions, Writing Testbenches in SystemVerilog, Lot of SystemVerilog Examples and SystemVerilog in One Day Tutorial. It’s 8 bits, so the tool selects 8-bit LFSR with polynomial coefficients taken from the table in .

Parameters Parameters are very handy. I would recommend using them frequently. I tried implementing LFSR using Verilog , but I am unable to get the output properly, please check the verilog code for both module and test bench below:- //LFSR.v `timescale 1ns / 1ps mod Pattern generators like LFSR (Linear Feed Back Shift Registers) can produce random patterns with low hardware requirements and is preferred choice for testing. It is categorized under pseudo-random test pattern generators which can produce a random pattern for every clock cycle applied to it.

LFSR is a shift register whose random state at the output depends on the feedback polynomial. So it can count maximum 2n-1 states and produce pseudo-random number of the output.
