Error in Pnoise Analysis

    I am simulating a VCO for its phase noise. After running Pss and
    Pnoise analysis when i open direct plot>main form to plot phase noise
    i get following message in icfb window.
    Results pnoise_corr are not available for
    "...../VCO_jazz/simulation/VCO_top/spectre/schematic". Use results()
    for a list of available results."

    When i type results() in icfb window it gives:

    (designParamVals pss_td pss_fd output instance
    pnoise variables model
    )

    It open main form and i am able to plot phase noise, but even if i
    make lot of changes in my circuit like replacing noisy components by
    their ideal counterparts phase noise plot doesn't changes at all. So i
    guess there is some problem and plot which i am getting is not the
    correct one.

    I would really appreciate if someone could help me get out of this.

    Thanks,
    Abhishek
