Hi,
I tried your layout and everything works fine.
Please find below the TB, with a correct stimuli process, and attached a snapshot of the simulation.
Remember that you have to ADD YOUR STIMULI in the Testbench template.
library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;
use work.components_pnml.all;
use work.definitions_pnml.all;
entity tb_pNML_custom_XORNEW is
end tb_pNML_custom_XORNEW;
architecture Behavioural of tb_pNML_custom_XORNEW is
signal CLK : std_logic;
signal O :std_logic;
signal O_param : param_data := (others => 0.0);
signal X :std_logic;
signal X_param : param_data := (others => 0.0);
signal Y :std_logic;
signal Y_param : param_data := (others => 0.0);
component pNML_custom_XORNEW is
port(
O: out std_logic;
O_param: out param_data := (others => 0.0);
X: in std_logic;
X_param: in param_data := (others => 0.0);
Y: in std_logic;
Y_param: in param_data := (others => 0.0);
CLK: in std_logic);
end component;
begin
DUT : pNML_custom_XORNEW port map(O => O, O_param => O_param,
X => X, X_param => X_param,
Y => Y, Y_param => Y_param,
CLK => CLK);
clock_proc:process
begin
CLK<='0';
wait for t_clock * 1 sec;
CLK<='1';
wait for t_clock * 1 sec;
end process clock_proc;
input_proc: process
begin
--insert your input stimuli here
x<='0';
y<='0';
wait for 5 us;
x<='0';
y<='1';
wait for 5 us;
x<='1';
y<='1';
wait for 5 us;
x<='1';
y<='0';
wait for 50 us;
end process input_proc;
end Behavioural;
