Unplaced IO pins

Greatrebel

Hi All, When I used checkDesign command in Encounter, I found there were a lot of unplaced IO pins. The number of unplaced IO pins is equal to the number of ports in my top-level design. I am wondering how to fix those unplaced IO pins or just leave them alone if it is not a big issue for P&R. Thanks in advanced

     Those unplaced pins are still there after routing, but I did not get an error for routing. The number of unplaced pins is not equal to the number of signal IOs but the port number of top module, since some ports have more than one bit.Does these unplaced pins really need to be clean out?

    Thanks
