Minimizing EM/IR Impacts On IC Design Reliability And Performance


By Joel Mercier and Karen Chow As technologies and foundry process nodes continue to advance, it gets more difficult to design and verify integrated circuits (ICs). The challenges become even more apparent in 5nm and below nodes, and as the industry moves away from fin field-effect transistor (finFET) and into gate-all-around field-effect transistor (GAAFET) technologies. There are many prob... » 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

Fast And Simple Rigid-Flex PCB Bending EM Analysis Using Clarity 3D Solver


3D PCB Electromagnetic (EM) Bending Analysis Rigid-Flex PCBs have been used in many modern electronic devices (such as mobile phones, laptops, and wearables, among others), due to their form factor, light weight, and cost-effectiveness. Electromagnetic (EM) analysis of Rigid-Flex PCBs has always been a challenging task for many commercially available 3D numerical solver technologies (FEM and F... » read more

A New Vision For Memory Chip Design And Verification


Discrete memory chips are arguably the most visible reminder of the opportunities and challenges for advanced semiconductor design. They are manufactured in huge quantities, becoming key drivers for new technology nodes and new fabrication processes. Price fluctuations have a major impact on the financial health of the electronics industry, and any shortages can shut down the manufacturing line... » read more

Radar Wave Propagation Through Materials


This white paper focuses on electromagnetic (EM) wave propagation through materials. For radar systems, this is of interest when radar must pass through walls, or when designing radomes (cover casings for the radar system). In the process of designing a radome, you should always perform full EM simulation. However, the content of this white paper will help you to first estimate whether a radome... » 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

Best Practices For Efficient And Effective Planar EM Simulation


Designers of today’s complex, multi-featured communications products require accurate and fast electromagnetic (EM) simulation to deliver cost-effective, high-performance products to market in ever-shrinking windows of opportunity. The Cadence AWR AXIEM 3D planar method-of-moments (MoM) EM analysis simulator within the AWR software portfolio delivers the accuracy, capacity, and speed designer... » read more

Using Analytics To Reduce Burn-in


Silicon providers are using adaptive test flows to reduce burn-in costs, one of the many approaches aimed at stemming cost increases at advanced nodes and in advanced packages. No one likes it when their cell phone fails within the first month of ownership. But the problems are much more pressing when the key components in data warehouse servers or automobiles fail. Reliability expectations ... » read more

Preparing For Electromagnetic Crosstalk Challenges


By Magdy Abadir and Anand Raman Electromagnetic (EM) coupling/noise is not a new phenomenon, but increasing bandwidth and decreasing size, along with low-power demands of today’s electronic systems is making EM crosstalk a first order challenge. At clock frequency of 10GHz+ and data rate of 10Gbps+, parasitic inductance and inductive coupling that were previously safe to ignore are no long... » read more

SoC Electromagnetic Crosstalk: From A Tool Perspective


Most commercial electromagnetic (EM) solvers are limited by the size of the design that they can handle, or they may take a very large amount of time or memory to perform the task. These capacity, memory or runtime constraints often lead to dropping important details about the design and the surrounding environment, which in many cases can mask the effects of EM crosstalk, or can lead to the wr... » read more
