Gaussian Noise Generator (GNG) Verilog IP Core

Introduction

The Gaussian Noise Generator core generates white Gaussian noise of standard normal distribution, which can be used to measure BER to extremely low BER levels (~$10^{-15}$). The core uses a 64-bit combined Tausworthe generator and an approximation of the inverse normal cumulative distribution function, which obtains a PDF that is Gaussian to up to 9.1 $\sigma$.
