Array Methods

SystemVerilog provides following build in methods to help with usage of arrays. This methods can be used with fixed, dynamic, queues, and associative arrays.

Method	Description
sum	Returns sum of all array elements.
product	Returns product of all array elements.
and	Returns bitwise AND (&) of all array elements.
or	Returns bitwise OR (\|) of all array elements.
xor	Returns bitwise XOR (^) of all array elements.
min	Returns array element which is minimum of all elements.
max	Returns array element which is maximum of all elements.
unique	Returns all elements with unique values.

Example : Array Methods


  1 module array_methods();
  2 
  3 int data [0:9] = '{1,2,3,6,5,7,8,9,9,2};
  4 int queue [$];
  5 
  6 initial begin
  7   queue = data.min;
  8   $display("Min size element is %0d",queue.pop_front());
  9   queue = data.max;
 10   $display("Max size element is %0d",queue.pop_front());
 11   $display("Sum of array %0d",data.sum);
 12   $display("Product of array %0d",data.product);
 13   $display("XOR of array %0d",data.xor);
 14   $display("AND of array %0d",data.and);
 15   $display("OR  of array %0d",data.or);
 16 end
 17 
 18 endmodule
