VHDL gate level simulation using quartus prime lite edition, error


I've designed an adder and the related testbench. I've run the RTL simulation, and it works as I expect, however I can't run the gate level simulation.


adder.vhd


library ieee;
use ieee.std_logic_1164.all;


entity adder is
port(x : in std_logic_vector(3 downto 0);
y : in std_logic_vector(3 downto 0);
z : out std_logic_vector(4 downto 0));
end entity adder;

architecture rtl of adder is
signal c : std_logic_vector(3 downto 0);
begin
adder_gen : for i in 0 to 4 generate

half_adder_gen : if i = 0 generate
z(i) <= x(i) xor y(i);
c(i) <= (x(i) and y(i));
end generate half_adder_gen;
full_adder_gen : if 0 < i and i < 4 generate
z(i) <= x(i) xor y(i) xor c(i-1);
c(i) <= (x(i) and y(i)) or ((x(i) or y(i)) and c(i-1));
end generate full_adder_gen;
overflow_gen : if i = 4 generate
z(i) <= c(i-1);

end generate overflow_gen;
end generate;
end architecture rtl;

adder_tb.vhd


library ieee;
use ieee.std_logic_1164.all;

entity adder_tb is
end entity adder_tb;


architecture tb of adder_tb is
signal clk : std_logic;
constant period : integer := 10;

component adder is
port(x : in std_logic_vector(3 downto 0);
y : in std_logic_vector(3 downto 0);
z : out std_logic_vector(4 downto 0));
end component adder;


signal x, y : std_logic_vector(3 downto 0);
signal z : std_logic_vector(4 downto 0);

begin

adder_comp : adder
port map(x => x, y => y, z => z);

clk_process : process

begin
clk <= '0';
wait for 5 ns;
clk <= '1';
wait for 5 ns;
end process;

inputs_submitt : process(clk)
variable counter : integer := 0;
begin

if(clk'event and clk = '1') then
if(counter mod 2 = 0) then
x <= X"A";
y <= X"B";
else
x <= X"5";
y <= X"6";
end if;
end if;
end process;


end architecture tb;

From the menu I do "processing -> start -> analysis and synthesis", it compiles fine. Then I do tool -> run simulation tool -> gate level simulation", after this ModelSim is being opened and what I get is the following error:


vsim -t 1ps +transport_int_delays +transport_path_delays -sdftyp /adder_inst=adder_vhd.sdo -L altera -L altera_lnsim -L cyclonev -L gate_work -L work -voptargs="+acc"  adder_tb
# ** Error (suppressible): (vsim-SDF-3196) Failed to find SDF file "adder_vhd.sdo".

# Error loading design
# Error: Error loading design

# Pausing macro execution
# MACRO ./adder_run_msim_gate_vhdl.do PAUSED at line 12

Any suggestions?


Update: When I run analysis and synthesis the following is the output:
