Arria V Avalon-MM Hard IP for PCIe PLL lock

Is there a pin from the Avalon-MM Arria V Hard IP for PCI Experess that I can monitor the serdes_pll_locked signal or someother downstream signal I can infer the pll lock state. I am getting an occasional reset from the PCIe core(during and ESD event). I have mostly ruled out the reset going into the part and would like to determine if my clock is remaining stable.

I am using quartus version 18.1.0 and the part is an 5AGXMB7G4F35I5.

    Hello,

    You can create another pin connected to the serder_pll_locked or coreclkout_hip clock signal with platform designer to monitor the pll locked signal.
