How do I report powered-down transceivers and PLLs in Quartus Prime Standard?

I have an issue which looks like an xcvr_fpll_a10_0 may not be powered or is shut down. How can I confirm that all the PLLs are in fact powered on in Quartus?

Hi,

Unfortunately clkusr is a must requirement. clkusr provided clock to transceiver channel to perform power on calibration during FPGA power up stage before FPGA enter user mode.

In your case, the transceiver channel may already gone wild and malfunction during power up stage due to missing clock before you can perform any transceiver operation (be it loopback test or anything) after FPGA enter user mode.

So, I don't think it will works and whatever test result on transceiver is not reliable as well.

Thanks.

How do I force the transceiver to restart calibration? My PCS has the reconfiguration avalon interface attached to an avalon master.
