High-Capacity Power Signoff Using Big Data

As designs increase in complexity to cater to the insatiable need for more compute power spurred by different AI applications ranging from data centers to self-driving cars, designers are constantly faced with the challenge of meeting the elusive PPA (Power Performance and Area) targets.

PPA over-design has repercussions resulting in increased product cost as well as potential missed schedules with no guarantee of product success. Advanced SoCs pack more functionality and performance which result in higher power density. Traditional approaches of uniformly over-designing the power grid which has worked in the past is no longer an option with routing resources becoming severely constrained. To add to these woes, there are hundreds of combinations of PVT corners to solve for along with the increasing number of applications.  Continue reading

Driving Towards Autonomous Cars and ADAS – The Future is Now

Remote Sensing System of Vehicle. various cameras and sensors of autonomous vehicles ADASRead any automotive-related article and I’m sure it discusses autonomous cars and Advanced Driver Assistance Systems (ADAS)  – the benefits, the challenges and what the future may hold. More and more auto makers are moving towards autonomous developing vehicles, but many of the systems that will eventually be integrated into these vehicles to make them fully autonomous are being developed today. In fact, you probably have some of them in the car you are driving now — Collision Mitigation Braking,  Lane Departure Warning, Blind Spot Warning, and Lane Keeping Assistance to name a few. These ADAS applications present a new set of challenges and require a multi-disciplinary development approach. You can read more about these development areas in a blog written by my colleague, Sandeep Sovani.

The Great Mobility Revolution – Planes, Trains and Automobiles

For most of human history, our mode of mobility was feet — our own feet, or those of some domesticated animal. Whenever we wanted to go somewhere, we walked or used horses. These quadrupeds remained the dominant mode of inter-city and intra-city transport for over two thousand years. Then in the mid-nineteenth century, the mode of inter-city transport changed over from horses to railways. Another half a century later the horse also disappeared from cities and towns as intra-city transport was taken over by automobiles. In the mid-twentieth century airplanes became the dominant mode of inter-city travel in North America, with railways continuing in addition to airplanes in Europe and Asia.

And that’s where we are today — stuck with trains, planes and automobiles for nearly a century. But not for long. Continue reading

Fast-Tracking ADAS and Autonomous Vehicles Development with Simulation

autonomous vehiclesA revolution is underway in the transportation industry. The rise of autonomous vehicles will transform the industry and society itself as much as the nineteenth century shift from horse-carriages to automobiles did.

However, developing autonomous vehicle technology is a formidable challenge. It requires ambitious new developments in sensing technologies, machine learning and artificial intelligence, that are not only unprecedented in the automotive industry, but in all other industries as well.

Driving Toward the Future with AUTOSAR Compliant Software

autosar complianceToday’s automotive systems are more complex, smarter and more autonomous than ever before, featuring functionality that no one could have imagined 10 years ago. Advanced sensors and electronics control everything from a vehicle’s speed and position to its entertainment and communications technologies. Radar, cameras and other sophisticated electronics are increasingly being incorporated into consumer vehicles.

In fact, today, more than 60 percent of a car’s cost comes from its advanced electronics and software systems. Since many of the functions guided by electronic systems are mission-critical, it’s essential that all automotive systems work together with complete reliability. The tens of millions of lines of software code that control these systems must be flawless. Continue reading

Design of Advanced Driver Assistance Systems – A CPS Approach

An automobile is the biggest and most complex connected device used by consumers today. Advanced driver assistance systems (ADAS) is one of the fastest growing automotive applications. Stringent government requirements on automotive safety, fuel consumption and technology-focused consumer preferences are fueling the growth of ADAS. Driven primarily by safety, ADAS capabilities were first implemented in premium vehicles as key differentiators to enhance the user experience and protect the vehicle and its occupants. It started with features like parking assistance, adaptive breaking systems (ABS), adaptive cruise control and tire pressure monitoring. Continue reading
