Why does the Fitter report show an incorrect "OCT_100ohms" receiver termination when external termination is used for Cyclone IV devices with Quartus II software versions 15.0 and earlier?

Description

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.

Resolution

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.
