In reply to Muthuvenkatesh:

This is invalid. “if(tr[1].exists())” you are calling the method which is not existed in transaction class. Several things that you need to do:

  1. transaction tr: This is dynamic array, you need create this array with specified number of elements.
    For example:

tr = new[10]; // 10 elements are created
  1. To check element is created or not, you can compare with null.

if(tr[1] != null)
  $display("class is available");
else
  $display("class is not available");

Note: If you use associated array, it provides you a method “exists” to check that current element is existed in array or not.
