convert boolean to std_logic

[manolis kaliorakis]

Hello to all,

I am a beginner in using vhdl. I want to convert a signal boolean to
std_logic. How could I achieve this?
I am using these libraries:

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;

Thanks in advance

KJ note: Do not use the following libraries, use ieee.numeric_std
instead

use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;

You have to create your own function...here it is

function To_Std_Logic(L: BOOLEAN) return std_ulogic is
begin
if L then
return('1');
else
return('0');
end if;
end function To_Std_Logic;
