Hi,
From image i can see that your top-level design name is PAUL but your entity name is ANDGATE.
We need to have entity name and name for top-level design same. change you entity name to PAUL instead of andgate.
Example : file name top.vhd set as top level entity.
entity TOP is
port ( ... );
end TOP;
architecture my_design of TOP is
begin
...
end my_design;
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
Best Regards,
Anand
