Understanding SerDes Signal Integrity Challenges
By Bill Fuller - 13 Apr, 2017 - Comments: 0

Signal integrity (SI) can perhaps best be defined as a set of measures of the quality of electrical signals, which are subject to the effects of noise, distortion and loss. Additional signal integrity issues include jitter, ringing, crosstalk, ground bounce and power supply noise. There are multiple factors that can negatively influence signal integrity, thereby causing errors and system fai... » read more

Creating Reliable SoCs For Safe ADAS Applications
By Ravi Ravikumar - 13 Apr, 2017 - Comments: 0

Every major automaker is in the process of bringing out autonomous vehicles with ADAS (advanced driver assistance systems). In addition to processors and embedded software, ADAS requires a variety of sensors – ultrasonic, camera, RADAR (radio detection and ranging), LIDAR (light detection and ranging), GPS and IR (infrared) – that are used to recognize signs, people, animals, other vehicles... » read more

Working With Custom Checkers In Dynamic Simulation Of Low Power Designs
By Progyna Khondkar - 13 Apr, 2017 - Comments: 0

Power-aware simulators can provide a wide range of automated assertions in the form of dynamic sequence checkers that cover every possible PA dynamic verification scenario. However, design specific PA verification complexities may arise from adoption of one or a multiple of power dissipation reduction techniques, from a multitude of design features — like UPF strategies — as well as from ta... » read more

Rethinking Computing For The AI Age
By Govind Wathan - 13 Apr, 2017 - Comments: 0

Cisco estimates that global cloud IP traffic will nearly quadruple in the next five years. Information consumption is exploding with artificial intelligence (AI) embedded into all devices and experiences surrounding us. However, we do not want that to come at a cost of our security and privacy. Talk about pressure. On you. Today, much of computing is done in the cloud for things that you are... » read more

Why You Need ASIL Certified Processor IP For Automotive Safety Applications
By Angela Raucher - 13 Apr, 2017 - Comments: 1

As the electronics content in automotive safety-related systems continues to grow, there are also an increasing number of new entrants into the automotive semiconductor market. To achieve automotive safety certification, specialized hardware and software is required. With this competitive pressure and consumer demand for safer vehicles, it is more important than ever to focus on cost savings an... » read more

Smart Antennas Come Into View
By Ann Mutschler - 09 Mar, 2017 - Comments: 1

Antennas are getting smarter, particularly in light of their increasing complexity, along with the intricacies of the environments — existing and new — they play in. There are interesting ways in which antennas are being integrated into the latest vehicles, some examples of which are in-vehicle approaches that range from a single antenna in the infotainment (behind the screen in front of... » read more

HBM2: It’s All About The PHY
By Bill Fuller - 09 Mar, 2017 - Comments: 0

HBM DRAM is currently used in graphics, high-performance computing (HPC), server, networking and client applications. HBM, says JEDEC HBM Task Group Chairman Barry Wagner, provides a “compelling solution” to reduce the IO power and memory footprint for the most demanding applications. Recent examples of second-generation HBM deployment include NVIDIA’s Quadro GP100 GPU which is paired wit... » read more

10nm And 7nm Routability – How Is Your CAD Flow Doing?
By Tobias Bjerregaard - 09 Mar, 2017 - Comments: 0

At DesignCon in January, I was a panelist at a panel session entitled “Power Integrity For 10nm/7nm SoCs - Overcoming Physical Design Challenges And TAT.” I was on the panel together with Arvind Vel, Sr. Director Applications Engineering, ANSYS, Inc. and Ruggero Castagnetti, Distinguished Engineer, Broadcom Limited. This topic is of course extremely broad, but it was interesting getting fee... » read more

New USB Audio Class For USB Type-C Digital Headsets
By Morten Christiansen - 09 Mar, 2017 - Comments: 0

The ¼” phone jack was invented more than 100 years ago to connect people using a new invention called the “telephone.” Today, the modern variant - the 3.5mm phone jack - is widely used. As modern mobile phones are used for more than phone calls and do not have room for multiple connectors, a new approach for audio connectivity is needed, so product designers are retiring the 3.5mm jack. ... » read more

Correlating Software Execution With Switching Activity To Save Power In SoC Designs
By Russell Klein - 09 Mar, 2017 - Comments: 0

There is probably no more pointless waste of energy than lighting and heating a room that is empty. The obvious optimization: notice that no one is there and turn off the lights. It works the same on an SoC or embedded system. To save energy, system developers are adding the ability turn off the parts of the system that are not being used. Big energy savings but with no compromise to functional... » read more
