I want to do monte carlo simulation on width and tickness of an
interconnect. How can i simulate interconnect in spice and variation
on that?

You will have to model the interconnection as a network of R and C
(and also possible L and G) elements like the "professional" layout
extractors does. If a device design guide is available for the process
you are using, there should be some guidelines on how to calculate the
parasitic resistance and capacitance to other layers. I have not seen
any process with statistical data on interconnects. Since you model an
interconnect with resistors and capacitors, it would be possible to
create the model circuit such that a variance can be applied. Problem
is just to get the data and what probability density function to use.
I don't know if metal process variation is gaussian.

If you are using spectre simulator there is a chapter dedicated to
Monte-carlo in the advanced analysis user manual.
