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 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


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

Achieving Physical Reliability Of Electronics With Digital Design


By John Parry and G.A. (Wendy) Luiten With today’s powerful computational resources, digital design is increasingly used earlier in the design cycle to predict zero-hour nominal performance and to assess reliability. The methodology presented in this article uses a combination of simulation and testing to assess design performance, providing more reliability and increased productivity. ... » read more

Verification’s Inflection Point


Functional verification is nearing an inflection point, brought on by rising complexity and the many tentacles that are intermixing it with other disciplines. New abstractions or different ways to approach the problems are needed. Being a verification engineer is no longer enough, except for those whose concerns is block-level verification. Most of the time and effort spent in verification i... » read more

RISC-V Verification Challenges Spread


The RISC-V ecosystem is struggling to keep pace with rapid innovation and customization, which is increasing the amount of verification work required for each design and spreading that work out across more engineers at more companies. The historical assumption is that verification represents 60% to 80% or more of SoC project effort in terms of cost and time for a mature, mainstream processor... » read more

10X Faster Electromagnetic 3D Simulation


Virtual prototypes are essential to optimize the signal integrity performance of their high-performance electronics products. Today, engineering teams are pushing to get fast electromagnetic (EM) simulations of printed circuit boards (PCB) and 3D chip packages in just a few hours with the highest level of accuracy. The state of the art in EM simulation has come a long way: Back in 2000 it wa... » read more

Simulating The Hyperloop


When SpaceX held the first Hyperloop Design Weekend Competition in Texas in January 2016, a team of five students from the Universitat Politècnica de València (UPV) in Spain, calling themselves Hyperloop UPV, won awards for Best Overall Concept Design and Best Propulsion System. The overall concept was to use magnetic levitation to give their Hyperloop vehicle a frictionless ride through t... » read more

HPC Appliance Boosts Simulation Performance


High-performance computing (HPC) resources can provide a substantial boost to simulation, but an HPC cluster can be complex and difficult to manage. By deploying a managed HPC cluster for ARA, the client was able to eliminate internal maintenance and support overhead, while improving productivity and reliability for their Ansys workloads.

System Simulation For RF Link Budget Analysis


This white paper examines how a more rigorous link budget analysis of an entire system can be determined through simulation, and how performing link budget analysis enables designers to address losses, gains, and power levels to meet the operational requirements of the radio communications system.
