Association internal signal - internal pin?

Can i associate an input of my entity that it is not a top level entity of my project to an internal pin of my board?

In particular i must use the sram of my cyclone ii , i want to create an entity sram in which i have an input chip enable, i want that this signal is the real chip enable of the sram.

Can i do it with the association of this input to the pin of my board?

And, how can i do it?

I seem that it is possible only for the top level entity.

    Yes it's only possible from the top level entity. If you want that signal to reach another entity, you'll have to connect it through the hierarchy. Declare it as a port in your entity, and in the instantiotion in the top level file, connect it to the pin.
