noise/jitter analysis of CDR in cadence

Dear sir,

I am designing a 5Gbs clock and data recovery using TSMC 0.18um library. I would like to generate an eye diagram and find p-p/rms jitter of my circuit. All of my circuits are using the TSMC tech lib.

Simulator version: MMSIM_12.11.284_lnx86 , IC51.41.15 . 

Subcircuits in my CDR: PD, FD, LCVCO, LPF, BUFFER. (Referenceless CDR

Input source: analogLib -> vsource -> bit. (A 5Gbs random data

I run transient analysis before but the pp clock jitter I got is extremely small(1.8ps) which seems extremely wrong comparing to others work .

Question:

1. Is transient analysis the only way to get the eye diagram? If so, should I turn on the transient noise and noise contribution? how to set these thing?

2. Should i perform other analysis at the same time when I run transient analysis?(ex: pnoise ...etc

I am confused about noise analysis in cadence while I know maybe some noise model already included in TSMC library

Thank you
