Cyclone III On-Chip Termination

Hi, I was wondering if anyone had a tutorial or instructions on how to enable the on-chip termination for the Cyclone III? On the Altera website, they mention that it can be done via assignment...

So do I have to add the pin names to my design (in the top entity), even though I'm not actually using them in the code?

What are you talking about? On-chíp termination (not reasonable with unused signals, I think) or weak pull-up resistors? The latter can be globally enabled for all unused pins which is the default setting with newer chips.

Cyclone III has only limited OCT capabilities by the way. So you should better clarify, what you mean.
