Please some help with this code, I dont know where is the problem, is 
giving me these errors:


Error: Node instance "TLong" instantiates undefined entity "OneShot"
Error: Node instance "TShort" instantiates undefined entity "OneShot"

here is the code...

library ieee;
use ieee.std_logic_1164.all;
use IEEE.STD_LOGIC_UNSIGNED.ALL;
entity TimerCircuits is 
port (LongTrig, ShortTrig, Clk: in std_logic;
TS,TL : buffer std_logic);
end entity TimerCircuits;
architecture TimerBehavior of TimerCircuits is 
component OneShot is 
port (enable, Clk : in std_logic;
    Duration : in integer range 0 to 25 ;
    QOut : buffer std_logic );
end component OneShot;
signal SetCountLong, SetCountShort: integer range 0 to 25; 
SetCountLong <= 25;
SetCountShort <=4;
TLong:OneShot port map (enable=>LongTrig, Clk=>Clk, Duration=>SetCountLong, QOut=>TL);
TShort:OneShot port map (enable=>ShortTrig, Clk=>Clk, Duration=>SetCountShort, QOut=>TS);
end architecture TimerBehavior;

The entity "OneShot" is not known here in this module. You must 
implement an entity "OneShot" and include it in the build process.

What toolchain give you that error?

Next time try this:

  VHDL code
