Consistent Test Reuse Across MIL, SIL, And HIL In A Model-Driven Development Workflow


This paper presents a standards-based, systematic, and automated generative MDD/XIL workflow that helps automotive developers develop their production ECU V&V suites early during software modeling and re-use them throughout the overall systems engineering project. The test cases developed during design can be re-used through to production ECU testing and ultimately for automated regression V&V ... » read more

Auto Displays: Bigger, Brighter, More Numerous


Displays are rapidly becoming more critical to the central brains in automobiles, accelerating the adoption and evolution of this technology to handle multiple types of audio, visual, and other data traffic coming into and flowing throughout the vehicle. These changes are having a broad impact on the entire design-through-manufacturing flow for display chip architectures. In the past, these ... » read more

Big Changes Ahead For Connected Vehicles


Carmakers are reworking their electronic architectures so they can tap into a growing number of external services and internal options, similar to the way a data center taps into various services over its internal network. In the past, this has been largely confined to internal services such as on-board Internet connectivity, and external traffic routing and music. The current vision is to g... » read more

The Case For FPGAs In Cars


Field-programmable gate arrays (FPGAs) thrive in rapidly evolving new markets before being replaced by hard-wired ASICs, but in automotive that crossover is likely to happen significantly later than in the past. Historically, FPGAs have held temporary positions until volumes increased enough to cost-reduce the FPGAs out in favor of a hardened version. With automobiles, there are so many chan... » read more

Security Concerns Rise For Connected Autos


The auto industry is transforming itself toward a future in which the automobile increasingly will be connected using V2X and 5G. Driver assistance will improve, and ultimately cars will be guided by AI and machine learning. But all of this will be closely watched by hackers, looking for an opening and a potentially large and untraceable payout. The replacement of mechanical functionality wi... » read more

Auto OEMs Face New Competitive Threats


Automotive design and manufacturing are undergoing a fundamental shift to the left as cars increasingly are electrified and chips take over more functions formerly done by mechanical parts, setting the stage for massive disruption across a supply chain that has been in place for decades. The success of Tesla — a company that had never actually built a chip or a car — was both a surprise ... » read more

Functional Safety For Fail-Operational Systems


Functional safety issues have long been an important part of product development wherever machine operations that are potentially dangerous for humans are carried out unattended. However, in terms of electrical and electronic systems, the need has been limited to a few industries such as medical technology and aerospace. Apart from that, the functional safety concepts were only used for niche p... » read more

Safeguarding Automotive Electronics


Modern automobiles can have up to 100 Electronic Control Units (ECUs) depending on their class, make, and model, with the number of ECUs rising even higher in the case of electric vehicles. An ECU is an embedded system in the car’s electronics. They are used to control all the vehicle's functions, including engine, powertrain, transmission, brakes, suspension, dashboard, entertainment system ... » read more

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
