VHDL-AMS - hAMSter

I am working in hAMSter, A VHDL AMS tool. I would like to know , whether I will be able to represent a random signal, whose data I have, as a SIGNAL to be processed in a hAMSter program. The hAMSter program is developed and it is working, only thing is I should send my random data from a dat file in to the hAMSter program by some file I/o process as a "SIGNAL" or some entity. Is it possible.
