Components from Packages

Component declarations may be made inside packages
- Components do not have to be declared in the architecture body

PACKAGE my_stuff IS
   COMPONENT and_gate
      PORT (in1, in2 : IN BIT;
            out1 : OUT BIT);
   END COMPONENT;
END PACKAGE my_stuff;


USE Work.my_stuff.ALL;
ARCHITECTURE test OF test_entity IS
     SIGNAL S1, S2, S3 : BIT;
BEGIN
   Gate1 : and_gate
     PORT MAP (S1, S2, S3);
END test;
