EDA Quartus13.0使用 1位全加器仿真.docx
要在Quartus中仿真全加器,您可以按照以下步骤进行操作:
1. 打开Quartus软件并创建一个新的工程。
2. 添加一个新的VHDL文件,该文件将包含全加器的代码。您可以使用以下代码:
```
library ieee;
use ieee.std_logic_1164.all;
entity full_adder is
port (
a, b, cin : in std_logic;
sum, cout : out std_logic
);
end full_adder;
architecture behavior of full_adder is
begin
sum <= a xor b xor cin;
cout <= (a and b) or (cin and (a xor b));
end behavior;
```
3. 添加一个新的测试台(testbench)文件,该文件将包含用于测试全加器的代码。以下是一个简单的测试台代码:
```
library ieee;
use ieee.std_logic_1164.all;
entity full_adder_tb is
end full_adder_tb;
architecture behavior of full_adder_tb is
component full_adder is
port (
a, b, cin : in std_logic;
sum, cout : out std_logic
);
end component;
signal a, b, cin, sum, cout : std_logic;
begin
uut : full_adder port map (a => a, b => b, cin => cin, sum => sum, cout => cout);
stim_proc : process
begin
a <= '0'; b <= '0'; cin <= '0'; wait for 10 ns;
a <= '0'; b <= '0'; cin <= '1'; wait for 10 ns;
a <= '0'; b <= '1'; cin <= '0'; wait for 10 ns;
a <= '0'; b <= '1'; cin <= '1'; wait for 10 ns;
a <= '1'; b <= '0'; cin <= '0'; wait for 10 ns;
a <= '1'; b <= '0'; cin <= '1'; wait for 10 ns;
a <= '1'; b <= '1'; cin <= '0'; wait for 10 ns;
a <= '1'; b <= '1'; cin <= '1'; wait for 10 ns;
wait;
end process;
result_proc : process
begin
wait for 80 ns;
assert sum = '0' and cout = '0' report "Test failed for case 1" severity error;
wait for 10 ns;
assert sum = '1' and cout = '0' report "Test failed for case 2" severity error;
wait for 10 ns;
assert sum = '1' and cout = '0' report "Test failed for case 3" severity error;
wait for 10 ns;
assert sum = '0' and cout = '1' report "Test failed for case 4" severity error;
wait for 10 ns;
assert sum = '1' and cout = '0' report "Test failed for case 5" severity error;
wait for 10 ns;
assert sum = '0' and cout = '1' report "Test failed for case 6" severity error;
wait for 10 ns;
assert sum = '0' and cout = '1' report "Test failed for case 7" severity error;
wait for 10 ns;
assert sum = '1' and cout = '1' report "Test failed for case 8" severity error;
wait;
end process;
end behavior;
```
4. 在仿真设置中添加测试台文件和全加器文件,然后运行仿真。
此时,您将能够看到仿真结果,以验证全加器的正确性。
