White Paper Explains Grounding Concepts in EM Simulators
February 18, 2010
One of the most misunderstood concepts with electromagnetic (EM) and circuit simulators and their results is how "ground" is defined and used within them. This white paper, written by EM expert Dr. John Dunn, demonstrates the importance of correctly selecting and assigning "ground" within EM simulators and how it is essential for successfully predicting the performance of board, package, and their associated interconnects. Specific examples at the board, package, and chip level are discussed as well as tips that can be used at the circuit level to aid ground studies.
