Growing Complexity Adds To Auto IC Safety Challenges


The automotive industry is working to streamline, automate and tame verification of automotive electronic control units, SoCs and other chips used in vehicles, many of which are becoming so complex and intertwined that progress is getting bogged down. Modern cars may have up to 100 ECUs, which control such vehicle functions as engine, powertrain, transmission, brakes, suspension, entertainme... » read more

Have Processor Counts Stalled?


Survey data suggests that additional microprocessor cores are not being added into SoCs, but you have to dig into the numbers to find out what is really going on. The reasons are complicated. They include everything from software programming models to market shifts and new use cases. So while the survey numbers appear to be flat, market and technology dynamics could have a big impact in resh... » read more

Data Strategy Shifting Again In Cars


Carmakers are modifying their data processing strategies to include more processing at or near the source of data, reducing the amount of data that needs to be moved around within a vehicle to both improve response time and free up compute resources. These moves are a world away from the initial idea that terabytes of streaming data would be processed in the cloud and sent back to the vehicl... » read more

Auto Power Becoming Much More Complex


Rising electronics content in automobiles is putting increased focus on automotive power delivery networks (PDNs). Safety implications mean that thorough power design and verification, along with novel power isolation techniques, are needed at the vehicle level, involving both electrical and mechanical considerations. The electronic takeover can be measured by the percentage that electronic ... » read more

PowerPR Virtualization: A Critical Feature For Automotive GPUs


What is GPU virtualization? Conceptually, virtualization is the capability of a device to host one or more virtual machines (VMs) that each behave like actual independent machines with their own operating system (OS), all running on the same underlying device hardware. In regard to GPUs, this means the capability to support multiple concurrently running operating systems, each capable of submit... » read more

Automotive E/E Architectures Are Key To Continued Innovation


Modern vehicles commonly are described as “computers-on-wheels” due to the recent explosion of computing power and electronic features manufacturers are equipping in their vehicles. The world’s first automobiles were relatively simple, and entirely mechanically operated. The first automotive electrical components were not even available until the 1930s, when manufacturers began offering v... » read more

Selecting an Approach to Build Flexible, Cost-Effective ECU Production Test Systems


Electronic control units (ECUs) were invented in the 1970s. At that time, people needed to improve fuel economy due to the oil crisis, which meant finding a way to make engines run cleaner and pollute less. Engines used a mechanical device called a distributor to control spark timing and a carburetor to control the fuel mixture. This mechanical system had minimal tuning and adjustment capabilit... » read more

TATA Motors Builds HIL Test System For Hybrid Vehicle Simulation Using NI Tools


The Challenge: Developing a scalable, flexible, and universal hardware-in-the-loop (HIL) platform to validate the integration of multiple electronic control units (ECUs) for a parallel hybrid vehicle. The Solution: Using the scalability of the PXI platform and the out-of-the-box functionality of NI VeriStand software to build a test system that could test six interconnected vehicle ECUs toge... » read more

Ethernet In Cars


The automobile is encountering possibly the biggest changes in its technological progression since the invention of the internal combustion engine nearly 150 years ago. Increasing levels of autonomy will reshape how we think about cars and car travel. It won’t be just a matter of getting from point A to point B while doing very little else — we will be able to keep on doing what we want whi... » read more

Self-Driving Cars Rattle Supply Chain


Automotive compute workloads are consolidating as carmakers push toward autonomous vehicles, but the changes necessary to make this all work are causing huge disruptions in an industry that has fine-tuned its supply chain over more than a century. Consolidation is essential for a variety of reasons, including efficiency of the computations, complexity management, and lower deployment costs. ... » read more
