VHDL standard packages and types


The following packages should be installed along with the VHDL

compiler and simulator. The packages that you need,

except for "standard", must be specifically accessed by each of

your source files with statements such as:



library IEEE;

use IEEE.std_logic_1164.all;

use IEEE.std_logic_textio.all;

use IEEE.std_logic_arith.all;

use IEEE.numeric_bit.all;

use IEEE.numeric_std.all;

use IEEE.std_logic_signed.all;

use IEEE.std_logic_unsigned.all;

use IEEE.math_real.all;

use IEEE.math_complex.all;



library STD;
