Referencing Efinix VHDL Libraries

The Efinity® software includes VHDL libraries for Trion and Titanium primitives. You use the library and use VHDL language constructs to reference these libraries:

library efxphysicallib;
use efxphysicallib.efxcomponents.all;

The following code shows how to reference the Efinix library:

Referring to the Efinix Library

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
library efxphysicallib;
use efxphysicallib.efxcomponents.all;

entity LUT4_VHDL is
   port
   (
      din : in std_logic_vector(3 downto 0);
      dout : out std_logic
   );
end entity LUT4_VHDL;
 
architecture Behavioral of LUT4_VHDL is
begin

 EFX_LUT4_inst : EFX_LUT4
   generic map (
      LUTMASK => x"8888"
   )
   port map (
      I0 => din(0),
      I1 => din(1),
      I2 => din(2),
      I3 => din(3),
      O => dout
   );

end architecture Behavioral;
