About monte carlo analysis

Hi all,
I want to simulate the offset of a comparator and want to follow the way mentioned in this document:
http://www.designers-guide.org/Analysis/comparator.pdf
However, i don't know how to store the comparator's results into a file. I used the sampler found in designer's guide community, the link is:
http://www.designers-guide.org/VerilogAMS/functional-blocks/smplr/sampler.vams
But the problem is the content of the file will be replaced each time when one run of Monte Carlo analysis is finished so that I can only get the comparator's results for the last run of Monte Carlo analysis.
I am just wondering how to store all comparator's results.
Thank you

It depends on what simulator you use.
What simulator do you use ?
Show me netlist regarding analysis statements including monte carlo analysis.

The simulator I use is Cadence Spectre

Set "savefamilyplots=yes" in montecarlo analysis statement.

Show me netlist regarding analysis statements including monte carlo analysis.
If you see result's data by using "Results Browser", there are many result's data.
Do you use correct data which include all trial data in monte carlo ?

I have solved my problem by modifying the sentence of "file = $fopen(filename)" to "file = $fopen(filename, "a")" in the VerilogA for sampler. In such a way that I can get all Monte Carlo simulation results
