The refclock_status output signal on the Agilex™ 7 F-Tile Reference and System PLL Clocks FPGA IP in Quartus® Prime Pro Edition Software version 23.2 is non-functional.
You should not use the refclock_status output signal. If you want to know the status of your System PLL reference clock, you can infer this by monitoring whether the out_systempll_synthlock_[n] tx_pll_locked[n], tx_ready[n], and rx_ready[n] signals assert high.
This problem is fixed beginning with the Quartus® Prime Pro Edition Software version 23.3.
