The myth about ground
Zhiping Yang, Google
GROUND is widely used in high-speed circuit modeling and simulation. However, there are a lot of misconceptions and misunderstandings about ground in the high-speed circuit industry. Does ideal ground really exist? If not, why do we use it in simulations? Should we connect the reference node of S-parameter model to ideal ground? Is ground bounce real and well defined? Should we put partial inductance and resistance on the ground net? What can we do or can not do with S-parameter model? These questions are commonly asked by high-speed circuit designers. Answers from different people may be quite different and even contradictory. In this presentation, these questions will be answered with some simple, but powerful examples. At the end, the audience should have a better understanding about the ground and how to use it in high-speed simulations.
