Description
Due to a bug in Quartus® II software version 14.1, the fitter report displays "unused" in the Termination column of Intel Arria 10 devices when both of the following conditions are true:
- Applying the LVDS I/O standard to the dedicated REFCLK pins
- Setting the dedicated REFCLK pin XCVR_A10_REFCLK_TERM_TRISTATE = TRISTATE_OFF .qsf assignment
The fitter report should display tristate_off.
Resolution
This problem is rebuilt in v15.0.
