View source for How to use SPICE models in Spectre

For the AMI 0.5um process, the SPICE model parameters are given for each fabrication run from the [http://www.mosis.com/cgi-bin/cgiwrap/umosis/swp/params/ami-c5 Wafer Electrical Test Data].  One example run is [http://www.mosis.com/cgi-bin/cgiwrap/umosis/swp/params/ami-c5/t99j-params.txt T99J] on Dec 22, 2009.  To incorporate this model into Spectre using the NCSU Cadence Design Kit (CDK), follow the steps given below:

# 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!):
