Just a little doubt regarding what are the sources considered in PNoise jitter analysis(only random or random+deterministic?).And how much accuracy can I expect if I calculate jitter using EyeDiagram function in Cadence Calculator?

PNoise jitter analysis is a type of noise analysis and so only considers random noise sources. I don't have experience with the EyeDiagram function but the accuracy of a jitter measurement in the eye diagram will proabably also depend on the accuracy settings (conservative/moderate/liberal) of the transient simulation.
