I created a core instance of XADC with XADC Wizard (3.0) and I instantiated it like this:
...
component temperatureMonitor
port (
daddr_in: in std_logic_vector(6 downto 0);
dclk_in: in std_logic;
den_in: in std_logic;
di_in: in std_logic_vector(15 downto 0);
dwe_in: in std_logic;
busy_out: out std_logic;
channel_out: out std_logic_vector(4 downto 0);
do_out: out std_logic_vector(15 downto 0);
drdy_out: out std_logic;
eoc_out: out std_logic;
eos_out: out std_logic;
ot_out: out std_logic;
alarm_out: out std_logic;
vp_in: in std_logic;
vn_in: in std_logic
);
end component;
...
temperature_monitor_instance: temperatureMonitor
port map (
daddr_in => monitorAddress,
dclk_in => Clock36M,
den_in => monitorDen,
di_in => monitorDataIn,
dwe_in => logicZero,
busy_out => open,
channel_out => open,
do_out => monitorDataOut,
drdy_out => monitorDrdy,
eoc_out => monitorEoc,
eos_out => open,
ot_out => monitorOverTamperatureAlarm,
alarm_out => open,
vp_in => logicZero,
vn_in => logicZero
);
...
When implementing the design with Vivado 2014.2 I get this error:
[Place 30-99] Placer failed with error: 'There are more instances than sites for type XADC'
Please review all ERROR, CRITICAL WARNING, and WARNING messages during placement to understand the cause for failure.
The target device is xc7a200tfbg484-3.
Any ideas what am I doing wrong?
