$CDS_TOP_DIR is the root directory of cadence. alternatively you can use $MMSIM_HOME/doc/spectreRF/spectreRF.pdf, since $MMSIM_HOME is $CDS_TOP_DIR/MMSIM. for your post related to pll simulation, see $MMSIM_HOME/doc/spectreRFvol2/spectreRFvol2.pdf

then it means you are using old version of MMSIM. contact your admin and update to at least MMSIM62, then you can use the tool described here:

try adding the following libraries to your cds.lib (if they exist)

$CDS_TOP_DIR/IC/tools/dfII/samples/artist/pllLib
$CDS_TOP_DIR/IC/tools/dfII/samples/artist/pllMMLib
