random number generation with LabVIEW FPGA

Hello,
 
I would like to implement some random number generation in LabVIEW FPGA. In fact, I need to generate a PWM signal with a fixed duty-cycle but with a frequency randomly varying for each period of my signal between 18kHz and 22kHz.
That's why I would like to generate a random number on the FPGA, and use it to calculate my random frequency.
Did someone already do something like that ? Is some algorithm (like the Random Number function for LabVIEW Windows) already exísting ?
Thanks in advance for the help,
 
Laurent

Hi Laurent,

Check out this DevZone article:

You should be able to extract the Uniform generator out of there pretty easily.
