There are projects that produce white noise, and from more than one type of device.
Some use an NPN with emitter-to-base operated in zener mode, or a zener diode, or a cheap noisy op amp. This method may or may not be available in simulator programs.
There are also commercial chips whose purpose is to generate white noise. An internet search will turn up some. One of these could be among the list of available devices in a simulator.
