====== Range names ======
===== Definition =====
==== slice_name ====
''[[.:bnf#prefix]] ( [[.:bnf#discrete_range]] )''

===== Example =====
Different slices are addressed.
  * The first slice addresses the range //0// to //7// of //r15// .
  * The second slice addresses the range //24// to //1// of //data// .
  * The third slice is invalid as the direction of indication in the declaration is opposed to that in the slice.

CONSTANT data : bit_vector(31 DOWNTO 0);

r15( 0 TO 7 ) ;
