I'm interested in the paper of Ken,"Predicting the Phase Noise and Jitter of PLL-Based Frequency Synthesizers". but I am a beginner of  this area, I want to repeat the experiment in this paper.What I need? I already have Spectre, but not SpectreRF.
Can I do behavioral simulation by spectre without changing ken's code in his paper?
If I can, How about the flow?
Thanks a lot!
