5.28 The Verilog code in Figure P5.9 represents a 3-bit linear-feedback shift register (LFSR) This type of circuit generates a counting sequence of pseudo-random numbers that repeats after 2" - 1 clock cycles, where n is the number of flip-flops in the LFSR. Synthesize a circuit to implement the LFSR in a chip. Draw a diagram of the circuit. Simulate the circuit's behavior by loading the pattern 001 into the LFSR and then enabling the register to count. What is...
