This shift register has a few key features: Can be enabled or disbled by driving en pin of the design Can shift to the left as well as right when dir is driven If rstn is pulled low, it will reset the shift register and output will become 0 Input data value of the shift register can be controlled by d pin. The design is instantiated into the top module and the inputs are driven with different values. The design behavior for each of the inputs can be observed at the output pin out. The time when it shifts its direction is highlighted in yellow. The time when data input pin remains constant is highlighted in blue.
