Thanks for the reply pletz.
Is there anyway to prevent the dangling ports from appearing in the pin planner. It´s just that i have to pass my part of the design onto another group and it just looks a bit untidy that they appear there when there are not really inputs and outputs. I tried simply deleting them but they reappear after the next compilation.
I understand that they are nothing to worry about but would be interested to know if there is a simple way to prevent them from appearing in the pin planner.
Manya thanks again,
