Fully parametrizable combinatorial parallel LFSR/CRC module - alexforencich/verilog-lfsr

Implements an unrolled LFSR next state Testing. Running the included testbenches Thanks. In web I found that I need to tap 64,63,62,61 bit for 64 bit LFSR. Also, I am new to verilog and this stuff and have very little knowledge. I want to drive a benchmark code using this lfsr. So what I want basically to design an lfsr that gives 64 bit output.

Module Declaration module top_module( input clk, input reset, // Active-high synchronous reset to 32'h1 output [31:0] q ); If the taps positions are carefully chosen, the LFSR can be made to be "maximum-length". A maximum-length LFSR of n bits cycles through 2 n-1 states before repeating (the all-zero state is never reached). The following diagram shows a 5-bit maximal-length Galois LFSR with taps at bit positions 5 and 3. 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.

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.

After that, the LFSR changes value at each clock cycle but never reaches 0, so it goes through only 255 8bit values (out of 256 possible combinations of a 8bit output) before starting again. Now, instead of outputting the full eight bits, we could output just one bit (i.e. choose any of the flip-flops to make the output, keep the other seven internal).

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.

large number of initial values are possible), then the generated numbers can be considered as random numbers for practical purposes.

HDL generation was correct and has not changed. Thanks for Rick Collins for bringing that to my attention. Updated 05/22/2000 - version 1.00 fixes the HDL code generation - looks good now.
