Advanced Driver Assistance Systems (ADAS) are intended to prevent deaths and injuries by reducing accidents. Exemplary ADAS applications include: pedestrian detection/avoidance, lane departure warning/correction; traffic sign recognition; automatic emergency braking, and; blind-spot detection. This FAQ starts with an overview of the “levels of driving automation” and its relation to ADAS. It then reviews the role […]
FAQ
Why voice over 5G relies heavily on LTE
Mobile phones are still phones. 5G devices need the ability to fall back to LTE when network support isn’t available. Here’s how and why.
Bug Hunt! Spiraling in on formal coverage closure
By Ping Yeung Ph.D., Principal Engineer, Siemens EDA Many companies have used formal verification to verify complex SoCs [1][2] and safety-critical designs. Using formal verification to confirm design functionalities and uncover functional bugs is emerging as an efficient verification approach. Although formal verification will not handle the complexity of a design at the SoC level, […]
All about multi-flex cable carriers used on robotic arms
Contributed by Jody Muelaner Good cable management is vital to the accurate and reliable operation of an industrial robot. Cables that catch and snag will affect the accuracy of a robot. Over time they will result in unplanned maintenance and excessive downtime. Robotic cell integrators have identified cable issues as the most significant cause of […]
Distributed power architectures and distributed power control
Distributed power architectures (DPAs) are many and varied. DPAs, including the dynamic bus architecture and the intermediate bus architecture, are evolving as a result of new power demands from FPGAs, CPUs, GPUs, ASICs. And the concept of a DPA has extended into distributed power control architectures (DPCAs) being developed for electric vehicle charging stations, renewable […]
What are ASILs and how do they work?
Automotive Safety Integrity Levels (ASILs) are a risk classification framework based on the ISO 26262 standard for Functional Safety for Road Vehicles. ISO 26262 is the adaptation of the IEC 61508 standards to address the specific needs of electrical or electronic (E/E) systems within road vehicles. This FAQ reviews the current status of the ASIL […]
VSWR and impedance, Part 6: Microstrip and stripline
Understanding the role and implications of impedance in RF transmission lines and antennas is vital to successful system performance. The traditional matching approaches are still in wide use, but new application requirements and advances in components, modeling and simulation, and manufacturing precision have also provided new ways to address the matching problem. Q: What is […]
VSWR and impedance, Part 5: Making a match
Understanding the role and implications of impedance in RF transmission lines and antennas is vital to successful system performance. The importance of impedance matching, minimizing reflections, and keeping a low VSWR means these topics have been studied extensively, ranging from analytical perspectives through many physical designs and implementations. This section looks at some matching techniques. […]
Solid-state EV batteries – are we there yet?
The short answer is ‘no.’ We might be getting closer, but there’s still no guarantee that we’ll get there soon. Some automakers are looking at 2024 for the introduction of solid-state batteries in EVs, but others don’t see that happening until 2030. Expectations are high but unfulfilled. This FAQ reviews the anticipated benefits of solid-state […]
Negotiate through 1/f noise challenges towards sample sizes into the 100s of years
Measuring and determining 1/f voltage noise over a multiple-year sample requires an operational amplifier and effective 1/f knowledge. This article shows how to identify and determine the actual op amp 1/f voltage noise across a sample size of years and explains why the 1/f voltage noise is a non-issue at higher frequencies. After many years […]
