use LFSR source in hspice

I usually create the pattern by using C++ routine and save it to a file which i then read as a source. Not sure how HSPICE would like it.
This way simulation is faster then making specialized schematic for the source(less transistors to play with)

Hi

Here is a Random-(Pseudo Random) generator:
It is a java applet that generates analog and VHDL signal patterns.
I have extracted it from my web Archives.
I think you may could not find it on the net.
The credits are of Mihai Munteanu.
