Electromagnetic Simulation And 3D-IC Interposers

By Matt Commens, Juliano Mologni, and Pete Gasperini Today’s 3D integrated circuit (3D-IC) technology is the culmination of 40 years of research in universities and laboratories scattered across the globe. Beginning with dynamic random-access memory (DRAM) deployments that appeared on the market a decade ago, 3D-IC has since expanded its reach. It is now decisively beginning to achieve the... » read more

The Foundations Of Computational Electromagnetics

Maxwell’s Equations can be expressed in multiple variants – there are integral and differential versions in both frequency and time domains, along with quasi-static and full-wave forms. Their elegance is evident upon sight yet for only the simplest systems are there known solutions. Thus, without assumptions to simplify the math and/or system under study, it is frequently impossible to full... » read more

The Physics Of Ports And Associated Ground For EM Simulators Serving RF Designs

The use of ports in electromagnetic (EM) simulators has evolved and matured over the years to make real-world design simulations practical. Having a foundational understanding of ports provides an intuitive skill in their proper selection and use in conjunction with circuit simulation. In this white paper, we examine ports common to EM simulators, which are the most common simulators for microw... » read more

The Impact Of Multiphysics On Production Electronic Design

For many electronic design professionals, it has become clear that the industry is transitioning through an inflection point that is shifting some of the ground rules of design. The increase in the speed and integration density in today’s systems are blurring the lines between chip design and traditional board or system design. This finds its fullest expression in multi-die, 3D integrated ... » read more

Innovations In High-Frequency Electromagnetic Simulation

High-frequency electromagnetic simulation has evolved from “wow, now I can see how electromagnetic fields behave” to needing to know how various EM fields interact in large, complex systems. During that time, I have been an R&D engineer and I have managed a team implementing various solver technologies. We’ve been presented with plenty of challenges as electronics have continued to pr... » read more
