Presented by: Richard Mellitz The purpose is to tie it together: signals, noise power, and performance. This is a primer on how signal integrity (SI) simulations work. The context is differential signaling with data rates greater than 25 Gb/s. Examples include 100 Gb/s NRZ signaling and relations to PAM. Reviews include SI assumptions such as linear time invariance (LTI), summing noise power, superposition, and statistical convolution. A variety of other impairments such as jitter, semiconductor noise, etc. will not be covered for simplicity.
