Due to a problem in the Quartus® II software versions 15.0 and earlier, the Fitter will incorrectly report a termination of "OCT_100ohms" on Cyclone® IV GX device receiver input pins when it has been disabled in the Quartus II software.
When disabled in the Quartus II software, the Fitter report\'s termination value is incorrect and can be ignored. The on-chip termination will disabled as intended.
This problem is scheduled to be fixed in a future release of the Quartus II software.
