edit: I just reinstalled lattice diamond and the updates, Active-hdl was installed automatically, but the simulation still gives me the same error. when i change library machXO3; use machXO3.all; to library machXO2; use machXO2.all; it compiles..
I'm trying to write a test bench for a simple implementation of OSCH, but I am not being able to get the testbench to work.
I managed to get it to work a few months ago but I lost the file I was working on.
this is the vhdl code I have:
library  ieee;
use  ieee.std_logic_1164.all;
-- For Main Clock --
library machXO3;
use machXO3.all;
--------------------
entity Clock is
     port (stdby : in std_logic;
           osc_int: out std_logic
           );
end Clock;
architecture Clock_behav of Clock is
    COMPONENT OSCH
    -- synthesis translate_off
        GENERIC (NOM_FREQ: string := "2.56");
    -- synthesis translate_on
        PORT (STDBY : IN std_logic;
              OSC : OUT std_logic
                );
    END COMPONENT;
begin
    Clock: OSCH
    -- synthesis translate_off
    GENERIC MAP( NOM_FREQ => "2.56" )
    -- synthesis translate_on
    PORT MAP (  STDBY => stdby,
                OSC => osc_int
    );
end Clock_behav;
This is the testbench, most of it was generated by lattice-diamond I only added stdby <= '0';
LIBRARY ieee;
USE ieee.std_logic_1164.ALL;
USE ieee.numeric_std.ALL;
ENTITY testbench IS
END testbench;
ARCHITECTURE behavior OF testbench IS 
    COMPONENT Clock
    PORT(
        stdby : IN std_logic;          
        osc_int : OUT std_logic
        );
    END COMPONENT;
    SIGNAL stdby :  std_logic;
    SIGNAL osc_int :  std_logic;
BEGIN
-- Please check and add your generic clause manually
    uut: Clock PORT MAP(
        stdby => stdby,
        osc_int => osc_int
    );
    stdby <= '0';
-- *** Test Bench - User Defined Section ***
   tb : PROCESS
   BEGIN
      --wait; -- will wait forever
   END PROCESS;
-- *** End Test Bench - User Defined Section ***
END;
Lattice-diamond is telling me that everything is okay, but when I run everything in Active-hdl, to simulate, I get these errors:
# Error: COMP96_0059: Main.vhd : (5, 1): Library "machXO3" not found.
