spectre model files for use in verilog ams

[Vineet]

Hi -
I am trying to use spectre built-in primitives in my verilog AMS
design using Cadence Environment tools. From cdsdoc, I understand that
I have to create a primitive table in the directory in which I have my
design. And apart from the primitive table, I should also have a model
file. I am able to locate the main primitive table in
/cadence/ldv41/tools.sun4v/affirma_ams/etc/files/spec_builtin.apt, but
I cant find the model files...There are some model files in
/cadence/local/models/spectre, but they are all NMOS or PMOS models. I
was looking for resitors, capacitors, etc. Is there a specific
directory where I can find these models?
In the Spectre Simulator Circuit Reference, Component Statements
2 section, I do see the descriptions for 'physical resistor'...so does
it mean that I have to create my own model files for all these
components? But then, I have been using Spectre to simulate my
schematics, and I have never had to create model files for the
capacitors I used in those schematics...so there should be some place
where these models should be stored right...?

Vineet.
