Range names

prefix ( discrete_range )

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.

SIGNAL r15 : bit_vector( 0 TO 31 ) ;
CONSTANT data : bit_vector(31 DOWNTO 0);
 
r15( 0 TO 7 ) ;
data( 24 DOWNTO 1 ) ;
data( 24 TO 25 ) ;
