Need help with the Code and Testbench, can someone please assist me, THANK YOU!!

Design a 16-bit Shifter unit with A, B, Type and Direction as inputs and ShiftOut as output. The value of A should be shifted or rotated by the value specified in B. The "Direction" bit is used to determine whether to shift/rotate left(0) or right(1). The "Op_Type" bit is used to determine whether to Shift(0) or Rotate(1) the data. This 16-bit Shifter has the following entity declaration: The "Direction" bit is used to determine whether to shift/rotate left (0) or right (1). The "Op_Type" bit is used to determine whether to shift(0) or rotate(1) The value of A should be shifted by the value specified in B. The shifted bits are replaced by 0 . Write a test bench that verifies the functionality of your design; make sure to have all possible operations of this unit in your test bench. Below table describes this unit's behavior: Report: VHDL code and waveforms
