Understanding Grounding Concepts In EM Simulators
By Dr. John M. Dunn, AWR Corporation
The misunderstanding of how ground is implemented in circuit simulation is one
of the most common misuses of electromagnetic (EM) simulators and their results. Ground in EM simulators and how to correctly choose among various grounding options are topics of special importance to designers using the results in a circuit simulator. Before it can be understood how ground is used in EM simulators, it is first necessary to understand how it works in circuit simulation. This article demonstrates how flexibility in selecting ground can help the engineer characterize board, package, and interconnect performance. Several specific examples at the board, package, and chip level are discussed. The article concludes with circuit tricks that can be used to aid in ground studies.
