When a module is invoked, Verilog creates a unique object from the template. Each object has its own name, variables, parameters, and I/O interface. The process of creating objects from a module template is called instantiation, and the objects are called instances. Each instance is a complete, independent and concurrently active copy of a module. -

LFSR (typically in the idle mode) such that the receiver can easily recover the state of the transmitter’s scrambler. Rather than exhaustively searching for alignment, the receiver’s ‘n’-bit descrambling LFSR is simply “primed” with the first ‘n’ bits received from the line. -
A linear feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state. The most commonly used linear function of single bits is XOR. Thus, an LFSR is most often a shift register whose input bit is driven by the exclusive-or (XOR) of some bits of the overall shift register value.

The implemented LFSR is coded for maximal length (2 N -1), where N is the number of bits in the LFSR. The VHDL entity can be instantiated with an LFSR bit width of 2 to 32. The parallel "seed" input port (same length as the bit width) can be used to start the LFSR sequence at a certain position in the pseudo-random sequence. -

May 12, 2019 · Linear-feedback shift register (LFSR) design in vhdl. May 12, 2019 By EG Projects. 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.

LFSR: produces an 11-bit pseudo-random number by setting the Least-Significant-Bit to the XOR of the two Most-Significant-Bits, thus accomplishing the feedback part of this module. Since this is a shift register, we use the 50MHz clock to initiate a shift and change the binary number currently being held. -
