VerilogA tunning for multilevel state capability

There is a verilogA model of a ferroelectric tunnel junctions (FTJ) device available that only supports two states. I want to adjust the characteristic variables in the verilogA code and tune the model to reproduce the multi-level (4 states. These four states have to be maapped to 4 conductance states measured in the lab. I want to learn how this work is done by you with the regular meetings as well as the having the documentation besides the tuned verilogA code reproducing the targeted 4 states. There is one-week deadline, I am wondering if you are willing to do this project.
