- Add an additional reset input, this should be an active low input. - Add the necessary code to implement this /reset feature.

The following outlines the process of adding the reset feature :- Add an additional input reset (call it r). Add an input pin (label as /Reset) Add to the existing always@ procedural block as a trigger, another sensitivity for the negative edge of the block input r Using if - test the Boolean status of the block input r. If statement is true, use another non-blocking assignment to assign 0 to r, the non-blocking assignment is also used in line 7.
