There is no tool which name is Cadence.
There are many simulators working in Cadence ADE.
Do you mean Cadence Spectre ?
Your purpose is just exercise of designing circuits using BJT ?
If so, use "$CDS_INST_DIR/tools/dfII/samples/artist/models/spectre/rfModels.scs".
You can find other model files in "$CDS_INST_DIR/tools/dfII/samples/artist/models/spectre"
If you want to do exercise of both circuit simulation and physical design using PDK, use gpdk180 or gpdk90 which Cadence provide as example of CMOS PDK.
