Create a new model file under "$CDK_DIR/models/spectre/nom" such as "ami06_t99j.m".
In the first line of the file, type "simulator lang=spice".
From the Wafer Electrical Test Data report (for T99J), copy the SPICE model parameters and paste them to the end of the new model file.
SPICE model parameters consist of two models: NMOS and PMOS. For each model, which is identifiable by the ".MODEL" keyword, name the model accordingly to how it is used by the transistor cells in Virtuoso. For the NCSU CDK in AMI 0.6um process, the NMOS model is named "ami06N", and the PMOS model is named "ami06P". The model statement lines should like something like the following:
.MODEL ami06N NMOS ( ...
.MODEL ami06P PMOS ( ...
As an example, the SPICE model file is given below for the T99J run (note, I found this model to be faulty -- DO NOT USE!):

Notes:
1. The Spectre parser has two modes. By default, Spectre is configured to expect Spice netlists unless told otherwise. When it reads simulator lang=spectre , it switches off Spice compatibility.
2. To switch back to accepting Spice netlists, use simulator lang=spice .When Spectre includes one file from another using the include statement, it automatically switches to Spice mode at the beginning of the new file, and returns to the previously active mode when it finishes reading it. For this reason, all Spectre netlists must begin with a lang=spectre statement.
