I create a  verilogA file to save some signals into a file during my simulation. It works.

Then I try to run Monte Carlo simulation. It turns out that everytime when a new run starts, my old data from previous run are all overwritten by the verilogA block. ('cause the file name is the same during monte carlo runs.)

So anybody knows how to append the data to a existing file? instead of overwrite it...

Thanks a lot.
