Arrays

Arrays are groups of elements, all of the same type !

type WORD is array (3 downto 0) of std_logic ;

index position

B_bus

What are the possible values for each element of the array ?

signal B_bus : WORD ;

type DATA is array (3 downto 0) of integer range 0 to 9 ;

Remember to specify the integer range, to limit width of synthesized module !

signal B_bus : DATA ;
