Hello,
I’ve a question. I want to constraint the sum of an array elements. For example:

rand int array[1000];

I want the sum of all elements to be 2345. Anyone has a method to do this using a constraint block in a UVM class

Thanks in advance

Use

constraint c_sum {array.sum() < 2345;}

You may want to use int unsigned if you do not want to consider negative numbers in the array.

Thanks Dave very much. Can this be used for an array of real values ?

rand real array[1000];

No. Real variables cannot be randomized, array or no array.
