RMS JITTER IN Phase locked loop

I am trying to calculate rms jitter for PLL. Will abs_jitter command in cadence calculator after selecting the clock suffice. The result, I get is absolute jitter. Is it the same as rms Jitter.

please advise

not sure, but it sounds like "absolute jitter" might mean peak to peak jitter, which is which you would deived by 2 to get peak jitter, and then again by (2)^1/2 to get RMS.
