hello
I am studying the use of VIO in a simple program. Enter a binary number by VIO and turn on that number in the leds of the fpga. But i get this error
[DRC 23-20] Rule violation (MDRV-1) Multiple Driver Nets - Net PROBE_IN0[0] has multiple drivers: i_7/O, U_VIO/inst/PROBE_OUT_ALL_INST/G_PROBE_OUT[0].PROBE_OUT0_INST/Probe_out_reg[0]/Q.
program top
entity LEDS_VIO is
end entity;
architecture Behavioral of LEDS_VIO is
signal Entrada : std_logic_vector(7 downto 0);
signal Salida : std_logic_vector(7 downto 0);
signal clk : std_logic;
component LEDS is
port
(
clk : std_logic;
Entrada : in std_logic_vector(7 downto 0);
Salida : out std_logic_vector(7 downto 0)
);
end component;
component vio_0 is
port
(
CLK : IN STD_LOGIC;
PROBE_IN0 : IN STD_LOGIC_VECTOR(7 DOWNTO 0);
PROBE_OUT0 : OUT STD_LOGIC_VECTOR(7 DOWNTO 0)
);
end component;
begin
U_VIO : vio_0
port map
(
CLK => clk,
PROBE_IN0(7 downto 0) => Entrada,
PROBE_OUT0(7 downto 0) => Salida
);
u_LEDS: LEDS port map
(Entrada => Entrada,
Salida => Salida,
clk => clk
);
end Behavioral;
other part of the program
entity LEDS is
Port ( clk : in std_logic;
Entrada : in STD_LOGIC_VECTOR (7 downto 0);
Salida : out STD_LOGIC_VECTOR (7 downto 0));
end LEDS;
architecture Behavioral of LEDS is
begin
Salida <= Entrada;
end Behavioral;
thanks for the help
