Innovations In High-Frequency Electromagnetic Simulation
By Rick Petersson - 07 May, 2021 - Comments: 0

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

Steep Spike For Chip Complexity And Unknowns
By Ed Sperling - 05 May, 2021 - Comments: 0

Cramming more and different kinds of processors and memories onto a die or into a package is causing the number of unknowns and the complexity of those designs to skyrocket. There are good reasons for combining all of these different devices into an SoC or advanced package. They increase functionality and can offer big improvements in performance and power that are no longer available just b... » read more

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

Next-Gen Design Challenges
By Ed Sperling - 20 Apr, 2021 - Comments: 0

As more heterogeneous chips and different types of circuitry are designed into one system, that all needs to be simulated, verified and validated before tape-out. Aveek Sarkar, vice president of engineering at Synopsys, talks with Semiconductor Engineering about the intersection of scale complexity and systemic complexity, the rising number of corners, and the reduced margin with which to buffe... » read more

Faster Than Moore’s Law: Exponential Innovation In Electromagnetic Simulation
By Larry Williams - 13 Apr, 2021 - Comments: 0

Moore’s Law is the most iconic statement of exponential technology advancement, doubling transistor count and hence functional performance every 24 months. Many pundits [1-3] have observed that while technology advancement is exponential, human expectations are linear. We often fail to anticipate when a technology may arrive in short order. Electromagnetic simulation has delivered exponential... » read more

OVP Guide To Using Processor Models

The OVP simulation technology from Open Virtual Platforms (OVP) and Imperas Software Limited enables very high performance simulation, debug and analysis of virtual platforms containing multiple processor and peripheral models. The OVP technology is extensible, provides the ability to create new models of processors and other platform components by writing C/C++ code that uses application progr... » read more

Modeling PCBs For Common Causes Of Failure
By Theresa Duncan - 11 Feb, 2021 - Comments: 0

By Theresa Duncan and Michael Blattau When designing printed circuit boards (PCBs), keep in mind the major causes of electronic failure: thermal cycling, vibration, and mechanical shock and drop. You can perform a variety of physical tests to determine how and why electronics fail, however, a much faster and cost-effective solution is PCB modeling and simulation. When simulation is used i... » read more

Optimizing Power Supply
By Cadence - 10 Feb, 2021 - Comments: 0

Any electrical engineer knows providing power to your board is a key feature in PCB design. While most boards can be functional, their true quality shines when the perfect level of power to components is achieved. Building and designing better power supplies is the best way to ensure the end-product has full life-cycle potential. But how do we ensure we can convert a (potentially variable) i... » read more
