Default alternative for lm386 in a Noise Generator

I'm trying to make a random noise for my circuit. It uses an LM386 audio amplifier in the end to boost the signal. But unfotunately this is not available in my simulation software. So I'm looking for a alternative either for LM386 or the whole noise generator circiut. The requirement is just to obtain a random signal that could mask an original triangular wave such that it appears as a random noise to an outside observer.

I hope I get a response soon.........

Do you mean a white noise generator ? Use a reverse biased B-E junction of a small signal transistor. One transistor, one resistor + a supply of at least 12 volt's or so. Any OpAmp to follow to boost level.
Or is it something else you mean
