charge pump output current noise (A^2/Hz) is SSB or DSB?

hi, i ran a pss/pnoise simulation of my charge pump in steady state,

the mmsim version is  14.10.708_lnx86
    /home/eda/tools/vendors/mmsim/14.10.708_lnx86/tools/bin/spectre -64  \
        input.scs +escchars +log ../psf/spectre.out -format psfxl -raw  \
        ../psf ++aps +mt=8 -proc 6 +lqtimeout 900 -maxw 5 -maxn 5  \
        -ahdllibdir  \

the cadence version is 6.1.6-64b
\o Program:             @(#)$CDS: virtuoso version 6.1.6-64b 09/01/2015 22:56 (sjfnl132) $
\o Hierarchy:           /home/eda/tools/vendors/opus/6.1.6.500.132_lnx86/tools.lnx86/dfII/
\o Sub version:         sub-version  IC6.1.6-64b.500.13.2  (64-bit addresses)


the simulation command is
noise type = source.

simulatorOptions options reltol=1e-3 vabstol=1e-6 iabstol=1e-12 temp=55.0 \
    tnom=27 scalem=1.0 scale=1.0 gmin=1e-12 rforce=1 maxnotes=5 maxwarns=5 \
    digits=5 cols=80 pivrel=1e-3 sensfile="../psf/sens.output" \
    checklimitdest=psf
pss  pss  fund=100M  harms=20  errpreset=conservative  tstab=2u

+       stop=66.65M  dec=10  maxsideband=20  oprobe=V32  separatenoise=yes

my question is, on the output current noise power. (A^2/Hz), is this reported

noise SSB or DSB?

i am seeing the chip noise being 6dB lower from my simulation. which would make sense if the reported number was DSB.

thanks alot.
