If your project is called micop, your toplevel need to have the same name.  

Whether it is HDL or schematic, make sure your toplevel also has the name micop.  Success, Ton

Dude, 

 your toplevel name must be same name of your file, for example, if mine file name is micop.v the code have to be like:  module micop (input x, output y);  assign x = y; endmodule   By  Full Altera in Brazil

If your project has many files it is good to right click on the top level file and execute the "set as top level" command. 

 This eliminates problems if you changed the name of the file that contains the top level.
