在Vivado中,可以使用以下代码实例化一个ILA:
```vhdl
library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;
entity my_design is
port (
clk : in std_logic;
reset : in std_logic;
data_in : in std_logic_vector(7 downto 0)
);
end entity my_design;
architecture rtl of my_design is
component ila
port (
clk : in std_logic;
probe0 : in std_logic_vector(7 downto 0);
probe1 : in std_logic_vector(7 downto 0);
probe2 : in std_logic_vector(7 downto 0);
probe3 : in std_logic_vector(7 downto 0)
);
end component;
begin
-- Instantiate ILA
ila_inst : ila
port map (
clk => clk,
probe0 => data_in,
probe1 => (others => '0'),
probe2 => (others => '0'),
probe3 => (others => '0')
);
-- Your design code here
end architecture rtl;
```
在上面的代码中,我们首先声明了一个名为`my_design`的实体,该实体具有三个端口:`clk`,`reset`和`data_in`。然后在该实体的体系结构中,我们声明了一个名为`ila_inst`的实例,并将其与`ila`组件相关联。在实例化过程中,我们将`clk`和`data_in`分别连接到`ila`组件的`clk`和`probe0`端口。`probe1`,`probe2`和`probe3`端口被连接到一个全0的向量上,因为我们不需要使用它们。最后,在`my_design`的体系结构中,我们可以编写我们的设计代码。
