The VHDL and Verilog code creates any N-Bit wide LFSR that you desire. It uses polynomials (which is the math behind the LFSR) to create the maximum possible LFSR length for each bit width. Therefore, for 3 bits, it takes 2 3-1=7 clocks to run through all possible combinations, for 4 bits: 2 4-1=15, for 5 bits: 2 5-1=31, etc. I based this on an XNOR implementation to allow the FPGA to start up in an all-zero state on the LFSR.

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…

Register-transfer level (RTL) models are quite popular in the industry as these can be easily synthesised using latest electronic design automation (EDA) tools. Long LFSR can be used as ‘ pseudo-random number generator ’. These random numbers are generated based on initial values to LFSR. The sequences of random number can be predicted if the initial value is known. the LFSR is designed and the outputs of the LFSR are connected to the ASIC’s inputs – one LFSR output for each ASIC input. Figure 3 shows how the LFSR outputs are multiplexed with the ASIC inputs so that the ASIC application logic can be verilog lfsr This will shifts the contents from MSB to LSB. module lfsr #(parameter LFSR_WIDTH = 8, TAP0 = 0, TAP1 = 2, TAP2 = 3, TAP3 = 4) (input clk, Most efficient way is to generate 'pseudo'-random numbers using LFSR when you want a h/w block to generate random numbers in your design (used mainly in DFT).

If the flip-flops have a set, use it. If not place inverters before and after the flip-flop to fake a set.
