For numeric types integer(X) yields the rounded value of the real variable X as an '1'); type Bit_vector is array (Natural range <>) of Bit; type Boolean is (false, 

3. * From Aldec: Active-HDL (simulation). Number and Character Representations in VHDL. Integers: For Integers default range in  XST accepts the following VHDL basic types: Enumerated As an example, " type MSB is range 8 to 15;" means any integer greater than 7 or less than 16.

subtype delay_length is time range 0 fs to time'high; \$\begingroup\$ The range of integer is -2*31+1 to 2**31-1. It depends on your optimizer to recognize if bits 4 to 31 are unused in your case. I recommend type unsigned(3 downto 0) to store values. \$\endgroup\$ – Paebbels Nov 5 '17 at 16:58 range permet d'indiquer l'intervalle 'HIGH indique la plus grande valeur du type INTEGER, c'est un attribut de type; Les types entiers servent à définir des indices de tableaux et de boucles.

VHDL interger range 怎么用？ 我想问一下，signale:integerrange0to8;是不是指随便怎么编，e的取值总是在0到8的范围里面，可能超过8吗？ 谢谢各位了！

Vhdl integer range

Value set is range 1 to integer'HIGH; SUBTYPE positive IS integer RANGE 1 TO integer'HIGH; real Value set is range of real (impl. dependent range); TYPE real IS RANGE -2_147_483_647.0 TO 2_147_483_647.0 ; Synthesis tools will infer an appropriate number of bits for enumerated and integer subtypes, depending on the range.

Composite types type barr is array (1 to 5) of bit; type v is array (integer range <>) of real; subtype farr is x ( 0 to 127); signal y : v(10 downto 0); attributes: v'length 

또한 정수형은 합성이 가능하며 범위를 지정하지 않을 경우 32비트가 된다. Convertir integer a std_logic_vector. Si estamos trabajando con integer, muchas veces será necesario traducirlos al tipo base std_logic_vector o traducir desde el tipo base a integer. En ese caso VHDL proporciona en las librerías funciones de conversión, a través de la librería numeric_std. Il faut donc définir une surcharge Synthesis tools will infer an appropriate number of bits for enumerated and integer subtypes, depending on the range.
