Top module name : SHIFTER (File name : SHIFTER.v) 2. Input pins: SHIFT [3:0], IN [15:0], SIGN, RIGHT. 3. Output pins: OUT [15:0]. 4. Input signals generated from test pattern are latched in one cycle and are synchronized at clock rising edge. 5. The SHIFT signal describes the shift number. The shift range is 0 to 15. 6. When the signal RIGHT is high, it shifts input data to right. On the other hand, it shifts input data to left. 7. When the signal SIGN is high, the input data is a signed number and it shifts with sign extension. However, the input data is an unsigned number if the signal SIGN is low. 8. You can only use following gates in Table I and need to include the delay information (Tplh, Tphl) in your design.
