How to use functions in packages on testbench code.

eg:

package my_function is

function to_max(a, b : integer) return integer is

variable output :integer;

begin

if (a > b)then

output := a;

return output ;

else

output := b;

return output;

end if;

end package my_functions

library ieee

library work

use work.my_functions.all

entity test_program is

port (

x,y : in integer;

y : out integer

);

architecture beh of test_program is

begin

y =to_max(x,y) ;

end architecture beh;

not synthesizable code but this is just a guide. hope it helps
