Series Termination with Calibration in Cyclone V

Hello,

The problem is that both is assigned to the same rzq. One calibration sets need a rzq by itself. It is only generating 1 calibrated termination control sets. When you fanout the termination control sets, the Quartus disallow it, because it doesn't have separate results. If all the pins should be using the same calibrated termination control set, then assign them to the same rzq. If 2 sets of pins using different calibrated termination control set, then you need separate rzq and calibration IP.

Hope this helps.

Thanks.
