Hello Yoni,
I do not believe you can do this directly. Although, you can create a
pseudo-random bit stream to drive a 1 volt piecewise linear voltage
source. Then drive your circuit with a dependant source that the piecewise
source controls and scale the voltage to the appropriate I/O level. I have
seen this method used by a number of SPICE users.
Good luck
