How to use pss-pnoise output noise spectrum in pll excess phase model

Hello

I ran PSS+Pnoise on LC VCO. Now i have output noise profile in sqr(v)/Hz vs offset frequency. Now i want to use this spectrum in PLL excess phase model(created in virtuoso)  to check how PLL will filter this noise.

Please can you help me how to do this. Because i am not getting any source in virtuoso which can read spectrum csv file.

With Regards
