5G OTA Test Not Ready For Production


5G is poised to dominate the wireless world, but over-the-air (OTA) testing of 5G beamforming antennas is still not ready for volume production. Beamforming is a critical element in the millimeter wave version of 5G, because of the limitations of ultra-high-frequency signals. Unlike 4G and its predecessors, millimeter wave technology will not penetrate objects, so signals need to be directed... » read more

Case Study—RF ASIC Validation Of A Satellite Transceiver


ASIC validation in the RF world comes with its own set of hurdles and challenges, with high-quality lab equipment, experience and know-how essential. A recently completed RF sub-system validation at S3 Semiconductors is presented in the form of a case study of the execution. The validation PCB design focussed on impedance matching and shielding RF signals from noise sources. We built up an effi... » read more

The Problem With Post-Silicon Debug


Semiconductor engineers traditionally have focused on trying to create 'perfect' GDSII at tape-out, but factors such as hardware-software interactions, increasingly heterogeneous designs, and the introduction of AI are forcing companies to rethink that approach. In the past, chipmakers typically banked on longer product cycles and multiple iterations of silicon to identify problems. This no ... » read more

AV Testing Advances Without Standards


The failure of the AV START Act in the United States Senate did more than just delay U.S. federal regulations for self-driving car technology that has yet to progress beyond the pilot-test stage. It delayed discussions that could have narrowed the almost infinite number of choices automated vehicles (AVs) must be prepared to make by creating guidelines defining what constitutes "safe" operat... » read more

What Is SOTIF?


Arteris IP’s Kurt Shuler discusses new system-level best-practices approach to automotive design that will be used for both diagnostics and forensics when something goes wrong with autonomous vehicles. https://youtu.be/nC3TkF7c0Oo » read more

Fast-Tracking Safe Autonomous Vehicles


You can't put a car on the road, a drone in the air or a robot in a warehouse without satisfying the strictest of safety standards. For an autonomous car, for example, this means driving billions of miles — a practical impossibility when time to market is critical. With ANSYS' complete solution for autonomous vehicles, you can put your machine through the required paces in a fraction of the t... » read more

Blog Review: May 9


Mentor's Doug Amos explains the differences (and similarities) between verification and validation, why switching between engines needs to be simpler, and why the limits of verification are driving a growth in validation importance. Synopsys' Melissa Kirschner provides a primer on 5G and the five technologies that will need to work in tandem to bring the promised high speeds and low latency.... » read more

Engineering Challenges for Viable Autonomous Vehicles


The rise of autonomous and electric vehicles brings with it a host of engineering implications, including an increase in the number and variety of sensors in the vehicle, increasing software and hardware complexity, massive validation and verification cycles, heightened safety and security requirements, and new demands for digital data continuity. This paper is an overview of how six interdisci... » read more

Interface DRC Can Streamline Chip-Level Interface Physical Verification


In most design companies, the chip-level physical implementation teams responsible for design floorplanning in place and route (P&R) environments also manage top-level physical verification from the early floorplanning stages through tapeout. In early floorplanning stages, blocks placed in the chip-level floorplan are usually still under development. Merging these incomplete blocks with the... » read more

Verification And Validation Brothers


At DVCon this year, Doug Amos took the stage for the [getentity id="22017" e_name="Mentor, a Siemens Business"] sponsored lunch presentation. For those of you who were there but decided to skip the lunch, expecting the traditional forced sales pitch, you made a mistake. Amos is one of those rare people who know how to inject humor, teaching and marketing into a single presentation such that the... » read more
