How Many Sensors For Autonomous Driving?
By John Koon - 01 Jun, 2023 - Comments: 0

With the cost of sensors ranging from $15 to $1,000, carmakers are beginning to question how many sensors are needed for vehicles to be fully autonomous at least part of the time. Those sensors are used to collect data about the surrounding environment, and they include image, lidar, radar, ultrasonic, and thermal sensors. One type of sensor is not sufficient, because each has its limitation... » read more

Accelerating Development of Software Defined Vehicles with Virtual ECUs
By Synopsys - 31 May, 2023 - Comments: 0

The automotive industry is going through a revolution. To adapt to new customer demands such as convenience, safety, autonomy, and electrification, the automotive industry is moving to software-driven vehicles. These require new, more powerful electrical/electronic (E/E) architectures and significantly increase the vehicle software content. They also force the industry to move from lengthy deve... » read more

Machine Vision Plus AI/ML Adds Vast New Opportunities
By John Koon - 17 May, 2023 - Comments: 0

Traditional technology companies and startups are racing to combine machine vision with AI/ML, enabling it to "see" far more than just pixel data from sensors, and opening up new opportunities across a wide swath of applications. In recent years, startups have been able to raise billions of dollars as new MV ideas come to light in markets ranging from transportation and manufacturing to heal... » read more

LPDDR Flash In Automotive
By Ed Sperling - 15 May, 2023 - Comments: 0

New automotive architectures are raising challenges for how to utilize memory effectively and efficiently. An LPDDR interface for flash allows different processors to utilize multiple banks of flash memory, which in turn reduces latency and interference. Sandeep Krishnegawda, vice president of marketing and applications at Infineon, talks about the new zonal controllers in automotive design and... » read more

Designing Crash-Proof Autonomous Vehicles
By John Koon - 10 May, 2023 - Comments: 0

Autonomous vehicles keep crashing into things, even though ADAS technology promises to make driving safer because machines can think and react faster than human drivers. Humans rely on seeing and hearing to assess driving conditions. When drivers detect objects in front of the vehicle, the automatic reaction is to slam on the brakes or swerve to avoid them. Quite often drivers cannot react q... » read more

Pinpointing Timing Delays Can Improve Chip Reliability
By Anne Meixner - 09 May, 2023 - Comments: 0

Growing pressure to improve IC reliability in safety- and mission-critical applications is fueling demand for custom automated test pattern generation (ATPG) to detect small timing delays, and for chip telemetry circuits that can assess timing margin over a chip's lifetime. Knowing the timing margin in signal paths has become an essential component in that reliability. Timing relationships a... » read more

3D Structures Challenge Wire Bond Inspection
By Karen Heyman - 09 May, 2023 - Comments: 1

Adding more layers in packages is making it difficult, and sometimes impossible, to inspect wire bonds that are deep within the different layers. Wire bonds may seem like old technology, but it remains the bonding approach of choice for a broad swath of applications. This is particularly evident in automotive, industrial, and many consumer applications, where the majority of chips are not de... » read more

How Safe Is Safe Enough?
By Frank Schirrmeister - 04 May, 2023 - Comments: 1

That was the overarching question a group of 180 experts discussed last week at the ISO 26262 & SOTIF conference for four days during #FuSaWeek2023 in Berlin. "How Safe is Safe Enough" is also the title of Prof. Koopman's book from September 2022. I mentioned him in my blog "Are We Too Hard On Artificial Intelligence For Autonomous Driving?" Prof. Koopman was referenced often in Berlin, and... » read more

Going Virtual In Automotive Electronics Development
By Filip Thoen - 04 May, 2023 - Comments: 0

Developing the electrical/electronic (E/E) systems in automobiles and other vehicles has always been challenging due to the rough environmental conditions experienced on the road and the high expectations for safety and reliability. In recent years, these challenges have been exacerbated by several industry trends. They have triggered a revolution in how electronic control units (ECUs) are desi... » read more

Hardware-Based Cybersecurity For Software-Defined Vehicles
By Lee Harrison - 04 May, 2023 - Comments: 0

As vehicle technology advances, so does the complexity of the electrical/electronic systems within these smart vehicles. A software-defined vehicle (SDV) relies on centralized compute and an advanced software stack to control most of its functionality, from engine performance to infotainment systems. SDVs are becoming more important as automakers look to improve vehicle performance, reduce emis... » read more
