Stratix II Digitally Controlled Impedance

Hello, thanks for responding to my post. I probably should have said "on-chip" termination. I did a search the only the information I found was http://www.altera.com/literature/an/an384.pdf. I email a vendor about on-chip termination and they mentioned DCI (Digitally Controlled Impedance). I guess I misunderstood him. I co-worker was using on-chip termination and it seems not to be working and I was trying to help.
