  • Hi Abhishek,

     

     Following is solution for a test-bench. I would recommend that you have an associative array (in case you are not utilizing all the elements). Just a thought why you would need such a huge array. Maybe you can revisit you are design and think of alternate ways instead of declaring a fixed array.  Also would recommend using bit instead of reg (2-state versus 4-state)
