Shift Register Verilog. At each clock cycle the content of the register shifts to the right and s in enters into the leftmost bit or the msb bit. We will now consider a shift register.
Verilog shift register basic concepts characteristics. Verilog n bit bidirectional shift register in digital electronics a shift register is a cascade of flip flops where the output pin q of one flop is connected to the data input pin d of the next. Load reg depth zeros end else if enable begin data reg data reg reg depth 2 0 data in.
Because all flops work on the same clock the bit array stored in the shift register will shift by one position.
Our shift register has an s in input entering on its left hand side. The whole design also has and output that we are c calling s out. The shift register which allows serial input one bit after the other through a single data line and produces a serial output is known as the serial in serial out shift register. A single bit shift register can be implemented in verilog using concatenation.
